  • 5889 Add default telemetry endpoint

Dependencies

Upgrade

Supported Platforms

We will provide technical support for NGINX Ingress Controller on any Kubernetes platform that is currently supported by its provider and that passes the Kubernetes conformance tests. This release was fully tested on the following Kubernetes versions: 1.25-1.30.

3.6.0

25 Jun 2024

Added support for the latest generation of NGINX App Protect Web Application Firewall, v5. NGINX Ingress Controller will continue to support the NGINX App Protect v4 family to allow customers to implement new Policy Bundle workflow at their own pace. NGINX App Protect WAF v5 does not accept the JSON based policies, instead requiring users to compile a Policy Bundle outside of the NGINX Ingress Controller pod. Policy bundles contain a combination of custom Policy, signatures, and campaigns. Bundles can be compiled using either App Protect compiler, or NGINX Instance Manager. Learn more here, https://docs.nginx.com/nginx-ingress-controller/installation/integrations/app-protect-waf-v5/.

With this release, NGINX Ingress Controller is implementing a new image maintenance policy. Container images for subscribed users will be updated on a regular basis in-between releases to reduce the CVE vulnerabilities. Customers can observe the 3.6.x tag when listing images in the registry and select the latest image to update to for the current release.

3.5.0

26 Mar 2024

NGINX Ingress Controller and NGINX App Protect WAF users can can now view violations through NGINX Instance Manager Security Monitor. Security Monitor can be used to build Policy bundles, reducing reload time impacts on NGINX Ingress Controller. Read more information in NGINX App Protect WAF Bundles and Security Monitoring.

When using NGINX Plus for two version split rollouts, you can now control progressive rollouts of a new backend version without reloading NGINX using the -weight-changes-dynamic-reload command line argument.

The use-cluster-ip annotation is now available for the Ingress resource. use-cluster-ip supports service meshes and specific use cases where the backend service should be the target instead of individual backend service pods, bypassing upstream load balancing.

3.4.0

19 Dec 2023

The default_server listeners for ports 80 and 443 can now be fully customized giving you the flexibility to shift the HTTP and HTTPS default listeners to other ports as your needs require.

Traffic splits now support weights from 0 - 100 giving you the control that you expect when performing canary roll outs of your back end services.

A new capability of “upstream backup” has been introduced for NGINX Plus customers. This gives you the control to set a backup service for any path. This takes advantage of NGINX health checks and will automatically forward traffic to the backup service when all pods of the primary service stop responding.

Dynamic reloading of SSL certificates takes advantage of native NGINX functionality to dynamically load updated certificates when they are requested and thus not require a reload when certificates update.

A number of Helm enhancements have come directly from our community and range from giving greater flexibility for HPA, namespace sharing for custom sidecars, and supporting multiple image pull secrets for greater deployment flexibility.

To make sure NGINX Ingress Controller follows Helm best practices, we’ve refactored our helm chart location. You can now find our helm charts under charts\nginx-ingress.

We’ve added the functionality to define App Protect WAF bundles for VirtualServers by creating policy bundles and putting them on a mounted volume accessible from NGINX Ingress Controller.

Features

  • 4574 Graduate TransportServer and GlobalConfiguration to v1.
  • 4464 Allow default_server listeners to be customised.
  • 4526 Update use of http2 listen directive to align with deprecation.
  • 4276 Use Lease for leader election.

Upgrade

3.3.0

26 Sep 2023

Overview

With release 3.3, NGINX Ingress Controller continues to advance capabilities for an ever-demanding set of use cases that go beyond simple layer 7 routing for services running exclusively in Kubernetes.

When involved in diagnostic operations and viewing the NGINX Plus console or when viewing the enhanced NGINX Plus metrics through Prometheus, customers now enjoy the added dimension of the backend service being available to aide in identification of issues as well as observing performance.

50% of our users continue to rely heavily on the Ingress resource and its “mergeable Ingress” usage pattern, to enhance the experience for these customers we have added the path-regex annotation with support for case sensitive, case insensitive, as well as exact regex match patterns.

Prometheus continues to be the most popular metrics platform for Kubernetes users. To further enhance ease of setting up integration with Prometheus we have finalized support for the Prometheus serviceMonitor capability. Providing better scraping controls for Prometheus admins.

For our most demanding customers performing a blue / green upgrade of the Ingress Controller itself supports the ability to provide their business customers an enhanced experience with no loss of session fidelity. Support for this pattern and others has been added through Helm chart enhancement that allows two deployments to share a single ingressClass resource and duplicate the same configuration.

To accommodate these enhancements, several new values have been added to our Helm chart, as well as modifications to existing values. Due to the potential impacts of these changes we have issued a major release to the Helm chart, advancing to v1.0.0

To better align with the demands of supporting additional protocols such as MQTT and QUIC, NGINX Ingress Controller is changing how listeners are defined for HTTP traffic. You have always had controls over the ports defined for TCP/UDP traffic through the GlobalConfiguration and TransportServer objects. That same flexibility has been introduced for HTTP/S traffic and the VirtualServer. This area will continue to expand to give customers full control over NGINX listeners so they can tailor to their specific needs and policies.

Features

  • 4023 Read Prometheus key/cert from memory.
  • 4080 Expose Location Zones metrics.
  • 4127, 4200, 4223 Add path-regex annotation for ingress.
  • 4108 Add command line argument for custom TLS Passthrough port.
  • 4271 Add custom listener controls to VirtualServer.

Fixes

  • 4160 Update JWT/JWKS policy validation.
  • 4371 Improve runtime batch reloads.

3.1.1

04 May 2023

Overview

This release reverts the changes made in 3.1.0 to use sysctls to bind to lower level ports without the NET_BIND_SERVICE capability. It also adds support for serviceNameOverride in the Helm chart, that can be used to override the service name for NGINX Ingress Controller. This is useful especially during an upgrade from versions prior to 3.1.0, to avoid downtime due to the service name change. To use this feature, set the serviceNameOverride value in the Helm chart to the name of the existing service.

For example, if the existing service name is my-release-nginx-ingress, you can use --set serviceNameOverride=my-release-nginx-ingress when running the upgrade command. Here is an example upgrade command that keeps the existing service name my-release-nginx-ingress for a deployment named my-release:

helm upgrade my-release oci://ghcr.io/nginxinc/charts/nginx-ingress --version 0.17.1 --set serviceNameOverride=my-release-nginx-ingress

Fixes

  • 3737 Update VirtualServer to ignore CRL for EgressMTLS.
  • 3722 Inherit NET_BIND_SERVICE from IC to Nginx. Thanks to Valters Jansons.
  • 3798 Update VirtualServer template to generate an internal jwt auth location per policy applied.

Features

  • 3491 Egress via Ingress VirtualServer Resource.

Dependencies

  • Update NGINX version to 1.23.4.
  • Update NGINX Plus version to R29.

Helm Chart

  • 3602 Updated NGINX Service Mesh references in Helm templates. Thanks to Jared Byers.
  • 3773 Swap cpu and memory in HPA template. Thanks to Bryan Hendryx.
  • 3802 Add serviceNameOverride. Thanks to Tim N.
  • 3815 Fix GlobalConfiguration name in Helm Chart.
  • 3862 Add correct indentation to controller-leader-election configmap helm template.

Upgrade

3.1.0

29 Mar 2023

Overview

  • Beginning with release 3.1.0 the NET_BIND_SERVICE capability is no longer used, and instead relies on net.ipv4.ip_unprivileged_port_start sysctl to allow port binding. Kubernetes 1.22 or later is required for this sysctl to be classified as safe. Ensure that you are using the latest updated deployment and daemonset example yaml files available in the repo.
  • The minimum supported version of Kubernetes is now 1.22. NGINX Ingress Controller now uses sysctls to bind to lower level ports without additional privileges. This removes the need to use NET_BIND_SERVICE to bind to these ports. Thanks to Valters Jansons for making this feature possible!
  • Added support for loading pre-compiled AppProtect Policy Bundles when using the -enable-app-protect cli argument. This feature removes the need for the Ingress Controller to compile NGINX App Protect Policy when NGINX App Protect Policy is updated.
  • IngressMTLS policy now supports configuring a Certificate Revocation Lists(CRL). When using this feature requests made using a revoked certificate will be rejected. See Using a Certificate Revocation List for details on configuring this option.
  • NGINX Ingress Controller now supports running with a Read-only Root Filesystem. This improves the security posture of NGINX Ingress Controller by protecting the file system from unknown writes. See Configure root filesystem as read-only for details on configuring this option with both HELM and Manifest. Thanks to Valters Jansons for making this feature possible!
  • HELM deployments can now set custom environment variables with controller.env. Thanks to Aaron Shiels for making this possible!
  • HELM deployments can now configure a pod disruption budget allowing deployments to configure either a minimum number or a maximum unavailable number of pods. Thanks to Bryan Hendryx for making this possible!
  • NGINX Ingress Controller uses the latest OIDC reference implementation which now supports forwarding access tokens to upstreams / backends. Thanks to Shawn Kim for making this possible!
  • The default TLS secret is now optional. This improves the security posture of NGINX Ingress Controller through enabling ssl_reject_handshake. This has the impact of immediately terminating the SSL handshake and not revealing TLS or cypher settings to calls that do not match a configured hostname.

Features

  • 3034 Allow extra args to be provided to the OIDC auth endpoint. Thanks to Alan Wilkie.
  • 3474 Add access token support in the OIDC. Thanks to Shawn Kim.
  • 3326 Add support for custom environment variables on the Nginx Controller container. Thanks to Aaron Shiels.

  • 3475 Ensure leader election is correctly disabled when option is set to false in helm template.
  • 3481 Add missing OSS internal routes for integration with NSM.
  • 3541 Ensure non-ready endpoints are not added to upstreams.
  • 3583 Update keyCache path for JWKs to avoid conflict with OIDC.
  • 3607 Clear Content-Length headers for requests processed by internal JWKS routes.

2.1.0

06 January 2022

Overview

  • Support for NGINX App Protect Denial of Service protection with NGINX Ingress Controller. More information about NGINX App Protect DoS. Examples for configuring NGINX App Protect DoS with NGINX Ingress Controller can be found here.

  • Full support for gRPC services using the NGINX Ingress Controller VirtualServer and VirtualServerRoute custom resource definitions. This makes configuring and supporting gRPC services much easier, giving a simple YAML configuration and removing the need for snippets. Resource definition examples for gRPC can be found here.

  • Implementation of NGINX mandatory and persistent health checks in VirtualServer and VirtualServerRoute to further reduce interruptions to your service traffic as configuration changes continuously happen in your dynamic Kubernetes environment(s). Health checks have been extended to include mandatory and persistent fields. Mandatory health checks ensures that a new upstream server starts receiving traffic only after the health check passes. Mandatory health checks can be marked as persistent, so that the previous state is remembered when the Ingress Controller reloads NGINX Plus configuration. When combined with the slow-start parameter, the mandatory health check give a new upstream server more time to connect to databases and “warm up” before being asked to handle their full share of traffic. See the settings here. More about the NGINX Plus mandatory and persistent health check features.

  • 2100 Add support for initContainers. Thanks to Gunnar Scherf.
  • 1827 Add support for wildcard cert in VirtualServer resources. Thanks to Simon Wachter.
  • 2107 Add option to download the NGINX Ingress Controller binary. Introduced a new TARGET download in the Makefile which can be used when building the NGINX Ingress Controller Docker image. With this option the Ingress Controller binary will be downloaded instead of built from source.
  • 2044 Upload NGINX Ingress Controller binaries to release.
  • 2094 AP: update appolicies crd.
  • 2216 Add grpc_status to the logs.
  • 2237 Unbind app-protect from -preview-policies.
  • 2273 Make the resource comparison more informative in case of an error. Thanks to Andrey Karpov.
  • 2124 Apply -enable-snippets cli arg to Ingresses. This PR extends the existing -enable-snippets cli argument to apply to Ingress resources. If snippets are not enabled, the Ingress Controller will reject any Ingress resources with snippets annotations. Previously, the argument only applied to VirtualServer, VirtualServerRoute and TransportServer resources. Please Note: this is a breaking change. See the UPGRADE instructions below.

Fixes

  • 2267 Fix URI rewrite in VirtualServers and VirtualServerRoutes.
  • 2260 Check if refresh token is undefined and do not store it in this case. Thanks to tippexs for the fix.

  • For NGINX Plus, use the 2.1.0 images from the F5 Container registry or build your own image using the 2.1.0 source code.
  • For Helm, use version 0.12.0 of the chart.
  • We changed the behaviour of snippets in Ingress resources by extending the existing -enable-snippets cli argument to apply to Ingress resources as well as VirtualServer, VirtualServerRoute and TransportServer resources. Because the default value of -enable-snippets is false, if you are using snippets in Ingress resources, you must explicitly set the -enable-snippets to true before upgrading the Ingress Controller, so that the new version of the Ingress Controller doesn’t reject Ingresses with snippets annotations.

2.0.0

28 September 2021

Overview

Release 2.0.0 includes:

  • Support for Ingress networking.k8s.io/v1. Kubernetes 1.22 removes support for networking.k8s.io/v1beta1. To support Kubernetes 1.22, NGINX Ingress Controller 2.0 is also compatible with only the networking.k8s.io/v1 version of the Ingress and IngressClass resources. This has the following implications:

    1. The minimum supported version of Kubernetes is now 1.19. For older Kubernetes versions, use the 1.12.x release of the Ingress Controller.

    2. For Kubernetes versions 1.19-1.21, you can continue using the networking.k8s.io/v1beta1 of the Ingress and IngressClass resources.

    3. For Kubernetes 1.22, you need to migrate your Ingress and IngressClass resources to networking.k8s.io/v1.

    4. If you are using the deprecated kubernetes.io/ingress.class annotation in your Ingress resources, it is recommended to switch to the ingressClassName field.

      We migrated all our documentation and examples to use networking.k8s.io/v1 and the ingressClassName field of the Ingress resource.

  • Scalability improvements. We improved the time for an Ingress Controller pod to become ready and start receiving traffic. This is especially noticeable when you have hundreds of Ingress or other configuration resources like VirtualServers: instead of several minutes or more in rare cases, a pod will become ready within a few minutes.
  • Documentation improvements We changed the look and feel of our documentation at https://docs.nginx.com/nginx-ingress-controller as well as the underlying publishing technology, which will allow us to bring even more improvements in the next releases.
  • Upgrade path for k8s.nginx.org/v1alpha1 Policy resource If you’re running release 1.9.0 and using the k8s.nginx.org/v1alpha1 Policy, the Ingress Controller now supports an upgrade path from v1alpha1 to v1 Policy version without downtime. See UPDATING POLICIES section below.

You will find the complete changelog for release 2.0.0, including bug fixes, improvements, and changes below.

Breaking Changes

  • 1850 Support Ingress and IngressClass v1.

Features

  • 1908 Add NTLM support to VirtualServer and VirtualServerRoute upstreams.
  • 1746 Add ingressClassName field to Policy.
  • 1956 Add v1alpha1 version back to policy CRD.
  • 1907 Remove libs compilation for OpenTracing in Dockerfile; add Zipkin and Datadog in addition to the already supported Jaeger tracer; additionally, for NGINX we now publish a Docker image with the tracers and the OpenTracing module on DockerHub: nginx-ic/nginx-plus-ingress:1.12.0-ot. Also thanks to MatyRi for upgrading OpenTracing in 1883.
  • 1788 Reload only once during the start. This significantly reduces the time it takes for an Ingress Controller pod to become ready when hundreds of Ingress or other supported resources are created in the cluster.
  • 1721 Increase default reload timeout to 60s: the Ingress Controller will wait for 60s for NGINX to start or reload. Previously, the default was 4 seconds.
  • 2009 Increase default upstream zone size for NGINX Plus. See the INCREASED UPSTREAM ZONES section below.

Fixes

  • 1926 Fix increased IC pod startup time when hundreds of VirtualServerRoutes are used
  • 1712 Allow make to build image when .git directory is missing.

Documentation

  • 1932 Add IAM instructions for NGINX Plus AWS Marketplace images.
  • 1927 Fix function name comments typo. Thanks to Sven Nebel.
  • 1898 Add instructions for configuring MyF5 JWT as a Docker registry secret for the F5 Container registry for NGINX Plus images.
  • 1851 Update docs and examples to use networking.k8s.io/v1.
  • 1765 Create documentation for pulling NGINX Plus images from the F5 Container registry.
  • 1740 Publish docs using Hugo and Netlify.
  • 1702 Add security recommendations documentation.

Helm Chart

  • Add new parameters to the Chart: controller.pod.extraLabels. Added in 1884.

Dependencies

  • 1855 Update minimum Kubernetes version to 1.19; remove the -use-ingress-class-only command-line argument, which doesn’t work with Kubernetes >= 1.19.
  • Update NGINX Plus version to R25. Note: images with NGINX App Protect will continue to use R24 until App Protect 3.6 is released.
  • Update NGINX version to 1.21.3.

Upgrade

  • For NGINX, use the 2.0.0 image from our DockerHub.
  • For NGINX Plus, use the 2.0.0 from the F5 Container registry or build your own image using the 2.0.0 source code.
  • For Helm, use version 0.11.0 of the chart.

See the complete list of supported images for NGINX and NGINX Plus on the Technical Specifications page.

INCREASED UPSTREAM ZONES

We increased the default size of an upstream zone from 256K to 512K to accommodate a change in NGINX Plus R25. The change makes NGINX Plus allocate more memory for storing upstream server (peer) data, which means upstream server zones will use more memory to account for that new data.

The increase in the zone size is to prevent NGINX Plus configuration reload failures after an upgrade to release 1.13.0. Note that If a zone becomes full, NGINX Plus will fail to reload and fail to add more upstream servers via the API.

The new 512K default value will be able to hold ~270 upstream servers per upstream, similarly to how the old 256K value was able to hold the same number of upstream servers in the previous Ingress Controller releases. You can understand the utilization of the upstream zones via NGINX Plus API and the NGINX Plus dashboard (the shared zones tab).

If you have a large number of upstream in the NGINX Plus configuration of the Ingress Controller, expect that after an upgrade NGINX Plus will consume more memory: +256K per upstream. If you don’t have upstreams with huge number of upstream serves and you’d like to reduce the memory usage of NGINX Plus, you can configure the upstream-zone-size ConfigMap key with a lower value. Additionally, the Ingress resource supports nginx.org/upstream-zone-size annotation to configure zone sizes for the upstreams of an Ingress resource rather than globally.

UPDATING POLICIES

This section is only relevant if you’re running release 1.9.0 and planning to upgrade to release 2.0.0.

Release 1.10 removed the k8s.nginx.org/v1alpha1 version of the Policy resource and introduced the k8s.nginx.org/v1 version. This means that to upgrade to release 1.10 users had to re-create v1alpha1 Policies with the v1 version, which caused downtime for their applications. Release 2.0.0 brings back the support for the v1alpha1 Policy, which makes it possible to upgrade from 1.9.0 to 2.0.0 release without causing downtime:

  • If the Policy is marked as a preview feature in the documentation, make sure the -enable-preview-policies command-line argument is set in 2.0.0 Ingress Controller.
  • During the upgrade, the existing Policies will not be removed.
  • After the upgrade, make sure to update the Policy manifests to k8s.nginx.org/v1 version.

Please also read the release 1.10 changelog for the instructions on how to update Secret resources, which is also necessary since some of the Policies reference Secrets.

Note that 2.1.0 will remove support for the v1alpha1 version of the Policy.

Supported Platforms

We will provide technical support for NGINX Ingress Controller on any Kubernetes platform that is currently supported by its provider and which passes the Kubernetes conformance tests. This release was fully tested on the following Kubernetes versions: 1.19-1.22.

  • The introduction of pre-built containers for advanced capabilities with NGINX Plus through the F5 Container Registry.
  • TransportServer supports TCP/UDP connections through the NGINX streams module adding support for matching specific health check response patterns for granular availability testing of your application, maximum connections to protect your applications from overload, supporting fine tuning of load balancing behavior, and snippets for advanced capability support as soon as you are ready to implement.
  • Availability through the AWS Container marketplace supporting Elastic Kubernetes Service.
  • NGINX App Protect capabilities have been extended to support the latest version and its capabilities.

You will find the complete changelog for release 1.12.0, including bug fixes, improvements, and changes below.

Features

  • 1633 Support match in TransportServer health checks.
  • 1619 Add AWS Marketplace Entitlement verification.
  • 1480 Add max connections to TransportServer.
  • 1479 Add load balancing method to TransportServer.
  • 1466 Support snippets in TransportServer.
  • 1578 Add support for CSRF protection in APPolicy.
  • 1513 Support multiple log security configs in Ingresses.
  • 1481 Add support for user defined browsers in APPolicy.
  • 1411 Add unary gRPC support in APPolicy.
  • 1671 Simplify Dockerfile stages for Debian.
  • 1652 Add HTTPS option to Prometheus endpoint.
  • 1646 Improve Dockerfile.
  • 1574 Add Docker image for Alpine with NGINX Plus.
  • 1512 Don’t require default server TLS secret.
  • 1500 Support ssl_reject_handshake in Ingress and VS.
  • 1494 Add logs around NGINX Plus binary/flag mismatch.
  • 1492 Update the IC so that GlobalConfiguration is not mandatory when configured.
  • 1500 Support ssl_reject_handshake in Ingress and VS. Previously, to handle missing or invalid TLS Secrets in Ingress and VirtualServer resources, the Ingress Controller would configure NGINX to break any attempts for clients to establish TLS connections to the affected hosts using ssl_ciphers NULL; in the NGINX configuration. The method didn’t work for TLS v1.3. Now the Ingress Controller uses ssl_reject_handshake on;, which works for TLS v1.3.
  • Documentation improvements: 1649.

Fixes

  • 1658 Add missing njs module to the openshift-image-nap-plus image.
  • 1654 Fix incorrect configuration and unexpected warnings about Secrets at the IC start.
  • 1501 Fix ungraceful shutdown of NGINX.
  • Documentation fixes: 1668, 1594 thanks to shaggy245, 1563, 1551.

Helm Chart

  • Add new parameters to the Chart: prometheus.scheme, prometheus.secret. Added in 1652.

Dependencies

  • 1604 Update NGINX Plus to R24. Previously, the Dockerfile had a fixed NGINX Plus version. Now the Dockerfile has a floating version that corresponds to the latest major NGINX Plus version. In the event of a patch version of NGINX Plus being released, make sure to rebuild your image to get the latest version (previously, we released a new Ingress Controller release in that case). Additionally, the AppProtect related packages are no longer fixed – the Dockerfile will always install the latest version of the packages that work with the latest NGINX Plus version.
  • Update NGINX version to 1.21.0.

Upgrade

  • For NGINX, use the 1.12.0 image from our DockerHub: nginx/nginx-ingress:1.12.0, nginx/nginx-ingress:1.12.0-alpine or nginx-ingress:1.12.0-ubi

1.11.0

31 March 2021

Overview

Release 1.11.0 includes:

  • Native NGINX Ingress Controller App Protect (WAF) policy
  • TransportServer improvements in terms of reliability, added features and operational aspects
  • Integration of NGINX Ingress Controller with Istio service mesh

You will find the complete changelog for release 1.11.0, including bug fixes, improvements, and changes below.

Features

  • 1317 Add status field to Policy resource.
  • 1449 Add support for ClusterIP in upstreams in VirtualServers/VirtualServerRoutes.
  • 1413 Add serverSnippets to TransportServer.
  • 1425 Add status field to TransportServer resource.
  • 1384 Add active health checks to TransportServer.
  • 1382 Add passive health checks to TransportServer.
  • 1346 Add configurable timeouts to TransportServer.
  • 1297 Support custom return in the default server. Thanks to 030.
  • 1378 Add WAF Policy.
  • 1420 Support IngressClassName in TransportServer.
  • 1415 Handle host and listener collisions for TransportServer resource.
  • 1322 Improve VirtualServer/VirtualServerRoute warnings for Policies.
  • 1288 Add stricter validation for some ingress annotations.
  • 1241 Refactor Dockerfile and Makefile.
  • Documentation improvements: 1320, 1326, and 1377.

Fixes

  • 1457 Wait for caches to sync when the Ingress Controller starts.
  • 1444 Fix setting host header in action proxy in VirtualServer/VirtualServerRoute.
  • 1396 Fix reload timeout calculation for verifying NGINX reloads.

Dependencies

Known Issues

  • 1448 When an Ingress Controller pod starts, it can report warnings about missing secrets for Ingress and other resources that reference secrets. Those warnings are intermittent - once the Ingress Controller fully processes the resources of the cluster, it will clear the warnings. Only after that, the Ingress Controller will become ready to accept client traffic - its readiness probe will succeed.

Upgrade

  • For NGINX, use the 1.11.0 image from our DockerHub: nginx/nginx-ingress:1.11.0, nginx/nginx-ingress:1.11.0-alpine or nginx-ingress:1.11.0-ubi
  • For NGINX Plus, please build your own image using the 1.11.0 source code.
  • For Helm, use version 0.9.0 of the chart.
  • 1241 improved the Makefile. As a result, the commands for building the Ingress Controller image were changed. See the updated commands here.
  • 1241 also consolidated all Dockerfiles into a single Dockerfile. If you customized any of the Dockerfiles, make sure to port the changes to the new Dockerfile.
  • 1288 further improved validation of Ingress annotations. See this document to learn more about which annotations are validated. Note that the Ingress Controller will reject resources with invalid annotations, which means clients will see 404 responses from NGINX. Before upgrading, ensure the Ingress resources don’t have annotations with invalid values. Otherwise, after the upgrade, the Ingress Controller will reject such resources.
  • 1457 fixed the bug when an Ingress Controller pod could become ready before it generated the configuration for all relevant resources in the cluster. The fix also requires that the Ingress Controller can successfully list the relevant resources from the Kubernetes API. For example, if the -enable-custom-resources cli argument is true (which is the default), the VirtualServer, VirtualServerRoute, TransportServer, and Policy CRDs must be created in the cluster, so that the Ingress Controller can list them. This is similar to other custom resources – see the list here. Thus, before upgrading, make sure that the CRDs are created in the cluster. Otherwise, the Ingress Controller pods will not become ready.

Supported Platforms

We will provide technical support for NGINX Ingress Controller on any Kubernetes platform that is currently supported by its provider and which passes the Kubernetes conformance tests. This release was fully tested on the following Kubernetes versions: 1.16-1.20.

  • Improved visibility with Prometheus metrics for the configuration workqueue and the ability to annotate NGINX logs with the metadata of Kubernetes resources.
  • NGINX App Protect User-Defined signatures support.
  • Improved validation of Ingress annotations.

You will find the complete changelog for release 1.10.0, including bug fixes, improvements, and changes below.

Features

  • 1304 Add Open ID Connect policy.
  • 1281 Add support for App Protect User Defined Signatures.
  • 1266 Add workqueue metrics to Prometheus metrics.
  • 1233 Annotate tcp metrics with k8s object labels.

  • Documentation improvements: 1282, 1293, 1303, 1315.

Helm Chart

  • 1290 Add new preview policies parameter to chart. controller.enablePreviewPolicies was added.
  • 1232 Replace deprecated imagePullSecrets helm setting. controller.serviceAccount.imagePullSecrets was removed. controller.serviceAccount.imagePullSecretName was added.
  • 1228 Fix installation of ingressclass on Kubernetes versions v1.18.x-*

Dependencies

  • 1299 Update NGINX App Protect version to 2.3 and debian distribution to debian:buster-slim.
  • 1291 Update NGINX OSS to 1.19.6. Update NGINX Plus to R23.

Upgrade

  • For NGINX, use the 1.10.0 image from our DockerHub: nginx/nginx-ingress:1.10.0, nginx/nginx-ingress:1.10.0-alpine or nginx-ingress:1.10.0-ubi

  • For NGINX Plus, please build your own image using the 1.10.0 source code.

  • For Helm, use version 0.8.0 of the chart.

  • As a result of 1270 and 1277, the Ingress Controller improved validation of Ingress annotations: more annotations are validated and validation errors are reported via events for Ingress resources. Additionally, the default behavior for invalid annotation values was changed: instead of using the default values, the Ingress Controller will reject a resource with an invalid annotation value, which will make clients see 404 responses from NGINX. See this document to learn more. Before upgrading, ensure the Ingress resources don’t have annotations with invalid values. Otherwise, after the upgrade, the Ingress Controller will reject such resources.

  • In 1232 controller.serviceAccount.imagePullSecrets was removed. Use the new controller.serviceAccount.imagePullSecretName instead.

  • The Policy resource was promoted to v1. If you used the alpha1 version, the policies are needed to be recreated with the v1 version. Before upgrading the Ingress Controller, run the following command to remove the alpha1 policies CRD (that will also remove all existing alpha1 policies):

     kubectl delete crd policies.k8s.nginx.org

    As part of the upgrade, make sure to create the v1 policies CRD. See the corresponding instructions for the manifests and Helm installations.

    Also note that all policies except for accessControl are still in preview. To enable them, run the Ingress Controller with - -enable-preview-policies command-line argument (controller.enablePreviewPolicies Helm parameter).

  • It is necessary to update secret resources. See the section UPDATING SECRETS below.

UPDATING SECRETS:

In 1225, as part of improving how the Ingress Controller handles secret resources, we added a requirement for secrets to be of one of the following types:

  • kubernetes.io/tls for TLS secrets.
  • nginx.org/jwk for JWK secrets.
  • nginx.org/ca for CA secrets.

The Ingress Controller now ignores secrets that are not of a supported type. As a consequence, special upgrade steps are required.

Before upgrading, ensure that the secrets referenced in Ingress, VirtualServer or Policies resources are of a supported type, which is configured via the type field. Because that field is immutable, it is necessary to either:

  • Recreate the secrets. Note that in this case, the client traffic for the affected resources will be rejected for the period during which a secret doesn’t exist in the cluster.
  • Create copies of the secrets and update the affected resources to reference the copies. The copies need to be of a supported type. In contrast with the previous options, this will not make NGINX reject the client traffic.

It is also necessary to update the default server secret and the wildcard secret (if it was configured) in case their type is not kubernetes.io/tls. The steps depend on how you installed the Ingress Controller: via manifests or Helm. Performing the steps will not lead to a disruption of the client traffic, as the Ingress Controller retains the default and wildcard secrets if they are removed.

For manifests installation:

  1. Recreate the default server secret and the wildcard secret with the type kubernetes.io/tls.
  2. Upgrade the Ingress Controller.

For Helm installation, there two cases:

  1. If Helm created the secrets (you configured controller.defaultTLS.cert and controller.defaultTLS.key for the default secret and controller.wildcardTLS.cert and controller.wildcardTLS.key for the wildcard secret), then no special upgrade steps are required: during the upgrade, the Helm will remove the existing default and wildcard secrets and create new ones with different names with the type kubernetes.io/tls.
  2. If you created the secrets separately from Helm (you configured controller.defaultTLS.secret for the default secret and controller.wildcardTLS.secret for the wildcard secret):
    1. Recreate the secrets with the type kubernetes.io/tls.
    2. Upgrade to the new Helm release.

Dependencies

  • 1182 Update NGINX version to 1.19.3.

Upgrade

  • For NGINX, use the 1.9.0 image from our DockerHub: nginx/nginx-ingress:1.9.0, nginx/nginx-ingress:1.9.0-alpine or nginx-ingress:1.9.0-ubi
  • For NGINX Plus, please build your own image using the 1.9.0 source code.
  • For Helm, use version 0.7.0 of the chart.

For Kubernetes >= 1.18, when upgrading using the manifests, make sure to update the ClusterRole and create the IngressClass resource, which is required for Kubernetes >= 1.18. Otherwise, the Ingress Controller will fail to start. If you run multiple NGINX Ingress Controllers in the cluster, each Ingress Controller must have its own IngressClass resource. As the -use-ingress-class-only argument is now ignored (see NOTES), make sure your Ingress resources have the ingressClassName field or the kubernetes.io/ingress.class annotation set to the name of the IngressClass resource. Otherwise, the Ingress Controller will ignore them.

Helm Upgrade

  • If you’re using custom resources like VirtualServer and TransportServer (controller.enableCustomResources is set to true), after you run the helm upgrade command, the CRDs will not be upgraded. After running the helm upgrade command, run kubectl apply -f deployments/helm-chart/crds to upgrade the CRDs.
  • For Kubernetes >= 1.18, a dedicated IngressClass resource, which is configured by controller.ingressClass, is required per helm release. Ensure controller.ingressClass is not set to the name of the IngressClass of other releases or Ingress Controllers. As the controller.useIngressClassOnly parameter is now ignored (see NOTES), make sure your Ingress resources have the ingressClassName field or the kubernetes.io/ingress.class annotation set to the value of controller.ingressClass. Otherwise, the Ingress Controller will ignore them.

Notes

  • When using Kubernetes >= 1.18, the -use-ingress-class-only command-line argument is now ignored, and the Ingress Controller will only process resources that belong to its class. See IngressClass doc for more details.
  • For Kubernetes >= 1.18, a dedicated IngressClass resource, which is configured by controller.ingressClass, is required per helm release. When upgrading or installing releases, ensure controller.ingressClass is not set to the name of the IngressClass of other releases or Ingress Controllers.

Added in 1035, 1034, 1029, 1003 thanks to RubyLangdon.
  • 1047 and 1009: Change how Helm manages the custom resource definitions (CRDs) to support installing multiple Ingress Controller releases. Note: If you’re using the custom resources (controller.enableCustomResources is set to true), this is a breaking change. See the HELM UPGRADE section below for the upgrade instructions.

Dependencies

  • Update NGINX version to 1.19.1.
  • Update NGINX Plus to R22.

Upgrade

  • For NGINX, use the 1.8.0 image from our DockerHub: nginx/nginx-ingress:1.8.0, nginx/nginx-ingress:1.8.0-alpine or nginx-ingress:1.8.0-ubi
  • For NGINX Plus, please build your own image using the 1.8.0 source code.
  • For Helm, use version 0.6.0 of the chart.

Helm Upgrade

If you’re using custom resources like VirtualServer and TransportServer (controller.enableCustomResources is set to true), after you run the helm upgrade command, the CRDs and the corresponding custom resources will be removed from the cluster. Before upgrading, make sure to back up the custom resources. After running the helm upgrade command, run kubectl apply -f deployments/helm-chart/crds to re-install the CRDs and then restore the custom resources.

Notes

  • As part of installing a release, Helm will install the CRDs unless that step is disabled (see the corresponding doc). The installed CRDs include the CRDs for all Ingress Controller features, including the ones disabled by default (like App Protect with aplogconfs.appprotect.f5.com and appolicies.appprotect.f5.com CRDs).

Helm upgrade

If leader election (the controller.reportIngressStatus.enableLeaderElection parameter) is enabled, when upgrading to the new version of the Helm chart:

  1. Make sure to specify a new ConfigMap lock name (controller.reportIngressStatus.leaderElectionLockName) different from the one that was created by the current version. To find out the current name, check ConfigMap resources in the namespace where the Ingress Controller is running.
  2. After the upgrade, delete the old ConfigMap.

Otherwise, the helm upgrade will not succeed.
