Installation with Helm

This document explains how to install F5 NGINX Ingress Controller using Helm.

Before you begin

Note:
All documentation should only be used with the latest stable release, indicated on the releases page of the GitHub repository.

Custom Resource Definitions

NGINX Ingress Controller requires custom resource definitions (CRDs) installed in the cluster, which Helm will install. If the CRDs are not installed, NGINX Ingress Controller pods will not become Ready.

If you do not use the custom resources that require those CRDs (which corresponds to controller.enableCustomResources set to false and controller.appprotect.enable set to false and controller.appprotectdos.enable set to false), the installation of the CRDs can be skipped by specifying --skip-crds for the helm install command.

Upgrade the CRDs

To upgrade the CRDs, pull the chart sources as described in Pull the Chart and then run:

kubectl apply -f crds/

Alternatively, CRDs can be upgraded without pulling the chart by running:

kubectl apply -f https://raw.githubusercontent.com/nginxinc/kubernetes-ingress/v3.7.1/deploy/crds.yaml

In the above command, v3.7.1 represents the version of NGINX Ingress Controller release rather than the Helm chart version.

Note:

The following warning is expected and can be ignored: Warning: kubectl apply should be used on resource created by either kubectl create --save-config or kubectl apply.

Check the release notes for a new release for any special upgrade procedures.

Uninstall the CRDs

To remove the CRDs, pull the chart sources as described in Pull the Chart and then run:

kubectl delete -f crds/
Warning:
This command will delete all the corresponding custom resources in your cluster across all namespaces. Please ensure there are no custom resources that you want to keep and there are no other NGINX Ingress Controller instances running in the cluster.

Manage the chart with OCI Registry

Install the chart

Run the following commands to install the chart with the release name my-release (my-release is the name that you choose):

  • For NGINX:

    helm install my-release oci://ghcr.io/nginxinc/charts/nginx-ingress --version 1.4.1

  • For NGINX Plus: (This assumes you have pushed NGINX Ingress Controller image nginx-plus-ingress to your private registry myregistry.example.com)

    helm install my-release oci://ghcr.io/nginxinc/charts/nginx-ingress --version 1.4.1 --set controller.image.repository=myregistry.example.com/nginx-plus-ingress --set controller.nginxplus=true

These commands install the latest edge version of NGINX Ingress Controller from GitHub Container Registry. If you prefer using Docker Hub, you can replace ghcr.io/nginxinc/charts/nginx-ingress with registry-1.docker.io/nginxcharts/nginx-ingress.

Upgrade the chart

Helm does not upgrade the CRDs during a release upgrade. Before you upgrade a release, see Upgrade the CRDs.

To upgrade the release my-release:

helm upgrade my-release oci://ghcr.io/nginxinc/charts/nginx-ingress --version 1.4.1

Uninstall the chart

To uninstall/delete the release my-release:

helm uninstall my-release

The command removes all the Kubernetes components associated with the release and deletes the release.

Uninstalling the release does not remove the CRDs. To remove the CRDs, see Uninstall the CRDs.

Edge version

To test the latest changes in NGINX Ingress Controller before a new release, you can install the edge version. This version is built from the main branch of the NGINX Ingress Controller repository. You can install the edge version by specifying the --version flag with the value 0.0.0-edge:

helm install my-release oci://ghcr.io/nginxinc/charts/nginx-ingress --version 0.0.0-edge
Warning:
The edge version is not intended for production use. It is intended for testing and development purposes only.

Manage the chart with Sources

Pull the chart

This step is required if you’re installing the chart using its sources. It also manages the custom resource definitions (CRDs) which NGINX Ingress Controller requires, and for upgrading or deleting the CRDs.

  1. Pull the chart sources:

    helm pull oci://ghcr.io/nginxinc/charts/nginx-ingress --untar --version 1.4.1

  2. Change your working directory to nginx-ingress:

    cd nginx-ingress

Install the chart

To install the chart with the release name my-release (my-release is the name that you choose):

  • For NGINX:

    helm install my-release .

  • For NGINX Plus:

    helm install my-release -f values-plus.yaml .

The command deploys the Ingress Controller in your Kubernetes cluster in the default configuration. The configuration section lists the parameters that can be configured during installation.

Upgrade the chart

Helm does not upgrade the CRDs during a release upgrade. Before you upgrade a release, see Upgrade the CRDs.

To upgrade the release my-release:

helm upgrade my-release .

Uninstall the chart

To uninstall/delete the release my-release:

helm uninstall my-release

The command removes all the Kubernetes components associated with the release and deletes the release.

Uninstalling the release does not remove the CRDs. To remove the CRDs, see Uninstall the CRDs.

Upgrade without downtime

Background

In NGINX Ingress Controller version 3.1.0, changes were introduced to Helm resource names, labels and annotations to fit with Helm best practices. When using Helm to upgrade from a version prior to 3.1.0, certain resources like Deployment, DaemonSet and Service will be recreated due to the aforementioned changes, which will result in downtime.

Although the advisory is to update all resources in accordance with new naming convention, to avoid downtime follow the steps listed below.

Upgrade steps

Note:
The following steps apply to both 2.x and 3.0.x releases.

The steps you should follow depend on the Helm release name:

  1. Use kubectl describe on deployment/daemonset to get the Selector value:

    kubectl describe deployments -n <namespace>

    Copy the key=value under Selector, such as:

    Selector: app=nginx-ingress-nginx-ingress

  2. Checkout the latest available tag using git checkout v3.7.1

  3. Navigate to /kubernates-ingress/charts/nginx-ingress

  4. Update the selectorLabels: {} field in the values.yaml file located at /kubernates-ingress/charts/nginx-ingress with the copied Selector value.

    selectorLabels: {app: nginx-ingress-nginx-ingress}

  5. Run helm upgrade with following arguments set:

    --set serviceNameOverride="nginx-ingress-nginx-ingress"
--set controller.name=""
--set fullnameOverride="nginx-ingress-nginx-ingress"

    It could look as follows:

    helm upgrade nginx-ingress oci://ghcr.io/nginxinc/charts/nginx-ingress --version 0.19.0 --set controller.kind=deployment/daemonset --set controller.nginxplus=false/true --set controller.image.pullPolicy=Always --set serviceNameOverride="nginx-ingress-nginx-ingress" --set controller.name="" --set fullnameOverride="nginx-ingress-nginx-ingress" -f values.yaml

  6. Once the upgrade process has finished, use kubectl describe on the deployment to verify the change by reviewing its events:

        Type    Reason             Age    From                   Message
----    ------             ----   ----                   -------
Normal  ScalingReplicaSet  9m11s  deployment-controller  Scaled up replica set nginx-ingress-nginx-ingress-<old_version> to 1
Normal  ScalingReplicaSet  101s   deployment-controller  Scaled up replica set nginx-ingress-nginx-ingress-<new_version> to 1
Normal  ScalingReplicaSet  98s    deployment-controller  Scaled down replica set nginx-ingress-nginx-ingress-<old_version> to 0 from 1

  1. Use kubectl describe on deployment/daemonset to get the Selector value:

    kubectl describe deployment/daemonset -n <namespace>

    Copy the key=value under Selector, such as:

    Selector: app=<helm_release_name>-nginx-ingress

  2. Checkout the latest available tag using git checkout v3.7.1

  3. Navigate to /kubernates-ingress/charts/nginx-ingress

  4. Update the selectorLabels: {} field in the values.yaml file located at /kubernates-ingress/charts/nginx-ingress with the copied Selector value.

    selectorLabels: {app: <helm_release_name>-nginx-ingress}

  5. Run helm upgrade with following arguments set:

    --set serviceNameOverride="<helm_release_name>-nginx-ingress"
--set controller.name=""

    It could look as follows:

    helm upgrade test-release oci://ghcr.io/nginxinc/charts/nginx-ingress --version 0.19.0 --set controller.kind=deployment/daemonset --set controller.nginxplus=false/true --set controller.image.pullPolicy=Always --set serviceNameOverride="test-release-nginx-ingress" --set controller.name="" -f values.yaml

  6. Once the upgrade process has finished, use kubectl describe on the deployment to verify the change by reviewing its events:

        Type    Reason             Age    From                   Message
----    ------             ----   ----                   -------
Normal  ScalingReplicaSet  9m11s  deployment-controller  Scaled up replica set test-release-nginx-ingress-<old_version> to 1
Normal  ScalingReplicaSet  101s   deployment-controller  Scaled up replica set test-release-nginx-ingress-<new_version> to 1
Normal  ScalingReplicaSet  98s    deployment-controller  Scaled down replica set test-release-nginx-ingress-<old_version> to 0 from 1

Run multiple NGINX Ingress Controllers

If you are running NGINX Ingress Controller releases in your cluster with custom resources enabled, the releases will share a single version of the CRDs.

Ensure the NGINX Ingress Controller versions match the version of the CRDs. When uninstalling a release, ensure that you don’t remove the CRDs until there are no other NGINX Ingress Controller releases running in the cluster.

The Run multiple NGINX Ingress Controllers topic has more details.
