Deploy using Helm

Overview

You can deploy F5 NGINX Instance Manager on Kubernetes using Helm. This method is quick, scalable, and supports both standard and lightweight modes.

New in 2.20.0

Starting with version 2.20.0, NGINX Instance Manager supports lightweight mode, which skips ClickHouse and disables metrics collection, ideal for simpler setups or resource-limited environments.

• Lightweight mode requires NGINX Agent v2.41.1 or later.

Starting with version 2.20.0, the Helm chart was renamed from nginx-stable/nms-hybrid to nginx-stable/nim. Chart versioning was also reset; v2.0.0 is the first release under the new name. Be sure to update your chart references if you’re using version 2.20.0 or later.

Requirements

To deploy NGINX Instance Manager using a Helm chart, you need:

Set up image registry access for NGINX Instance Manager

You can use your NGINX JWT as a Docker configuration secret with Helm charts.

Create a Docker registry secret on the cluster, using the JWT token as the username and none as the password. The Docker server is private-registry.nginx.com.

Make sure there are no extra characters or spaces when copying the JWT token. They can invalidate the token and cause 401 errors during authentication.

Kubernetes

kubectl create namespace nim
kubectl create secret docker-registry regcred \
  --docker-server=private-registry.nginx.com \
  --docker-username=<NGINX JWT Token> \
  --docker-password=none \
  -n nim

OpenShift

oc new-project nim && \
oc create secret docker-registry regcred \
  --docker-server=private-registry.nginx.com \
  --docker-username=<NGINX JWT Token> \
  --docker-password=none \
  -n nim

You might see a warning that --password is insecure. In this case, it’s safe to ignore—none is used as a placeholder.

As a best practice, you can delete the JWT token and clear your shell history after deployment if others have access to the system.

Confirm the secret

• Kubernetes

  Copy

  kubectl get secret regcred --output=yaml -n nim

• OpenShift

  Copy

  oc get secret regcred --output=yaml -n nim

You can now use this secret for Helm deployments and point the chart to the private registry.

Add the repository

Run the following commands to add the official NGINX Helm repository and update your local chart list.

helm repo add nginx-stable https://helm.nginx.com/stable
helm repo update

Create a values.yaml file

Create a file named values.yaml using the following example. This file customizes your NGINX Instance Manager deployment with Helm.

The values file lets you:

• Set the deployment mode
• Provide registry credentials
• Specify image sources for each NIM service

Set nmsClickhouse.mode to control ClickHouse deployment:

See the Helm chart configuration settings guide for a complete list of chart parameters.

nmsClickhouse:
  mode: internal # options: internal, external, disabled

# when mode is external, uncomment and set this:
# externalClickhouse:
#   address: <clickhouse-host>:<port>

imagePullSecrets:
  - name: regcred

apigw:
  image:
    repository: private-registry.nginx.com/nms/apigw
    tag: <version>
core:
  image:
    repository: private-registry.nginx.com/nms/core
    tag: <version>
dpm:
  image:
    repository: private-registry.nginx.com/nms/dpm
    tag: <version>
ingestion:
  image:
    repository: private-registry.nginx.com/nms/ingestion
    tag: <version>
integrations:
  image:
    repository: private-registry.nginx.com/nms/integrations
    tag: <version>
secmon:
  image:
    repository: private-registry.nginx.com/nms/secmon
    tag: <version>
utility:
  image:
    repository: private-registry.nginx.com/nms/utility
    tag: <version>

These values are required when pulling images from the NGINX private registry. The chart doesn’t auto-resolve image tags. Set each tag: value to match the NGINX Instance Manager version you want to install. Refer to the Helm chart table for version details.

Use the file with the -f values.yaml flag when installing the chart.

OpenShift support was added in NGINX Instance Manager 2.19. To enable it, add the setting openshift.enabled: true to your values.yaml file. For more details, see Appendix: OpenShift security constraints.

Install the chart

Install NGINX Instance Manager using Helm. The adminPasswordHash sets the default admin password.

helm install nim nginx-stable/nim \
  -n nim \
  --create-namespace \
  --set adminPasswordHash=$(openssl passwd -6 '<your-password>') \
  -f <your-values.yaml> \
  --version <chart-version> \
  --wait

• Replace <your-password> with your preferred admin password.
• Replace <your-values.yaml> with the path to your customized values.yaml file.
• Replace <chart-version> with the version you want to install (for example, 2.0.0).

Note: You can set the ClickHouse mode at install time instead of editing values.yaml:

For lightweight mode (no ClickHouse):

--set nmsClickhouse.mode=disabled

For external ClickHouse:

--set nmsClickhouse.mode=external \
--set nim.externalClickhouse.address=<clickhouse-host>:<port>

Validate the deployment

After installation, run the following command to confirm the deployment was successful:

helm status nim -n nim

You should see STATUS: deployed in the output.

To find the right NGINX Instance Manager chart version, see the following table:

Access the web interface

You can access the NGINX Instance Manager web interface using the external IP address for the API Gateway.

1. To look up the external IP address for the API Gateway, run the following command:

   Copy

   kubectl -n nim get svc apigw

   This kubectl command shows details for the apigw service in the nim namespace. You’ll see the service type, port, cluster IP, and external IP addresses.

   The default service type is ClusterIP and the output looks similar to the following example:

   text

   Copy

   NAME    TYPE        CLUSTER-IP      EXTERNAL-IP   PORT(S)   AGE
   apigw   ClusterIP   10.108.57.167   <none>        443/TCP   32s

   Using the CLUSTER-IP value, go to https://<CLUSTER-IP>:443/ui.

   For example, https://10.108.57.167/ui.

   This IP address might not be reachable, depending on how the Kubernetes cluster networking was configured. If so, the apigw service type can be changed to a more suitable option, such as LoadBalancer, by changing the Configurable Helm Setting value for apigw.service.type.

Add a license

A valid license is required to use all NGINX Instance Manager features.

For instructions on downloading and applying a license, see Add a License.

Upgrade NGINX Instance Manager

To upgrade your deployment:

1. Update the Helm repository list.
2. Review and adjust your values.yaml file as needed.
3. Run the following command to upgrade the deployment. This command uses the current chart version from the nginx-stable/nim repository and applies the configuration from your values.yaml file.

helm upgrade nim nginx-stable/nim \
  -n nim \
  --set adminPasswordHash=$(openssl passwd -6 '<your-password>') \
  -f <path-to-your-values.yaml> \
  --version <chart-version> \
  --wait

• Replace <your-password> with your preferred admin password.
• Replace <your-values.yaml> with the path to your customized values.yaml file.
• Replace <chart-version> with the version you want to install (for example, 2.0.0).

Save the password!

Only the encrypted version of the admin password is stored in Kubernetes. If you lose it, it can’t be recovered or reset. Make sure to save the password in a secure place.

If you’re upgrading from a deployment that used the legacy nms chart or release name, you’ll need to update the chart reference and adjust the release name as needed. The latest chart is now called nginx-stable/nim, and nim is the recommended release name.

Uninstall NGINX Instance Manager

To uninstall NGINX Instance Manager, run:

helm uninstall <release-name> -n <namespace>

This command removes the deployment and all Kubernetes resources managed by the Helm chart.

For example, if you used the default release and namespace names:

helm uninstall nim -n nim

Manage network policies

If you plan to use network policies, make sure your Kubernetes cluster has a supported network plugin installed before you install the Helm chart.

By default, the Helm chart creates a set of network policies for NGINX Instance Manager in the deployment namespace.

To view them:

• Kubernetes:

  Copy

  kubectl get netpol -n <namespace>

• OpenShift:

  Copy

  oc get netpol -n <namespace>

The number and names of network policies vary depending on the deployment mode (standard vs. lightweight). For example, in standard mode, you might see output like this:

NAME         POD-SELECTOR                     AGE
apigw        app.kubernetes.io/name=apigw     2m
core         app.kubernetes.io/name=core      2m
dpm          app.kubernetes.io/name=dpm       2m
ingestion    app.kubernetes.io/name=ingestion 2m
secmon       app.kubernetes.io/name=secmon    2m

If you’re using lightweight mode, your output may include fewer entries.

To disable network policies, add the following to your values.yaml file:

networkPolicies:
  enabled: false

Helm deployment for NGINX Instance Manager 2.19

Create a Helm deployment values.yaml file

The values.yaml file customizes the Helm chart installation without changing the chart itself. You can use it to set image repositories, environment variables, resource requests, and other options.

1. Create a values.yaml file like this example:

   • In the imagePullSecrets section, add your private Docker registry credentials.
   • Set the tag: field to the version of NGINX Instance Manager you want to install. You can find supported versions in the Helm chart table.

For details on creating a secret, see the Kubernetes Pull an Image from a Private Registry guide.

imagePullSecrets:
  - name: regcred

apigw:
  image:
    repository: private-registry.nginx.com/nms/apigw
    tag: <version>
core:
  image:
    repository: private-registry.nginx.com/nms/core
    tag: <version>
dpm:
  image:
    repository: private-registry.nginx.com/nms/dpm
    tag: <version>
ingestion:
  image:
    repository: private-registry.nginx.com/nms/ingestion
    tag: <version>
integrations:
  image:
    repository: private-registry.nginx.com/nms/integrations
    tag: <version>
secmon:
  image:
    repository: private-registry.nginx.com/nms/secmon
    tag: <version>
utility:
  image:
    repository: private-registry.nginx.com/nms/utility
    tag: <version>

2. Save and close the values.yaml file.

Install the chart

Run the helm install command to deploy NGINX Instance Manager:

1. Replace <path-to-your-values.yaml> with the path to your values.yaml file.

2. Replace <your-password> with a secure password (containing a mix of uppercase, lowercase letters, numbers, and special characters).

   Remember to save the password for future use. Only the encrypted password is stored, and there’s no way to recover or reset it if lost.

helm install -n nms-hybrid \
--set adminPasswordHash=$(openssl passwd -6 '<your-password>') \
nms nginx-stable/nms-hybrid \
--create-namespace \
-f <path-to-your-values.yaml> \
--version <chart-version> \
--wait

Upgrade NGINX Instance Manager

To upgrade:

1. Update the Helm repository list.

2. Adjust your values.yaml file if needed.

3. To upgrade the NGINX Instance Manager deployment, run the following command. This command updates the nms deployment with a new version from the nginx-stable/nms-hybrid repository. It also hashes the provided password and uses the values.yaml file at the path you specify.

4. Replace <chart-version> with the desired chart version of NGINX Instance Manager 2.19.x referring the Helm chart table.

   shell

   Copy

    helm upgrade -n nms \
    --set nms-hybrid.adminPasswordHash=$(openssl passwd -6 '<your-password>') \
    nms nginx-stable/nms-hybrid \
    -f <path-to-your-values.yaml> \
    --version <chart-version> \
    --wait

   • Replace <path-to-your-values.yaml> with the path to the values.yaml file you created](https://frontdoor-test-docs.nginx.com/previews/docs/1162/nginx-instance-manager/deploy/kubernetes/deploy-using-helm/#configure-chart).

   • Replace <your-password> with a secure password that includes uppercase and lowercase letters, numbers, and special characters.

     Save the password!

     Save this password for future use. Only the encrypted password is stored in Kubernetes, and you can’t recover or reset it later.

If you’re upgrading from version 2.18.0 or earlier to 2.19.x, note the following changes:

• If you used the legacy nms chart or release name, update the chart reference and adjust the release name if needed.
• The structure of the values.yaml file has changed in this release.

Helm Deployment for NGINX Instance Manager 2.18 or lower

Create a Helm deployment values.yaml file

The values.yaml file customizes the Helm chart installation without modifying the chart itself. You can use it to specify image repositories, environment variables, resource requests, and other settings.

1. Create a values.yaml file similar to this example:

   • In the imagePullSecrets section, add the credentials for your private Docker registry.
   • Change the version tag to the version of NGINX Instance Manager you would like to install. See “Install the chart” below for versions.

   For details on creating a secret, see Kubernetes Pull an Image from a Private Registry.

   • Replace YourPassword123# with a secure password that includes uppercase and lowercase letters, numbers, and special characters.

     Save the password!

     Save this password for future use. Only the encrypted password is stored in Kubernetes, and you can’t recover or reset it later.

Troubleshooting

For instructions on creating a support package to share with NGINX Customer Support, see Create a Support Package from a Helm Installation.

Appendix: OpenShift security constraints

OpenShift restricts containers from running as root by default. To support NGINX Instance Manager, the Helm chart creates a custom Security Context Constraint (SCC) when you set:

openshift:
  enabled: true

This ensures pods can run with the user IDs required by NGINX Instance Manager services.

When openshift.enabled: true is set in the values.yaml file, the NGINX Instance Manager deployment automatically creates a custom Security Context Constraints (SCC) object and links it to the Service Account used by all pods.

By default, OpenShift enforces strict security policies that require containers to run as non-root users. The deployment needs specific user IDs (UIDs) for certain services—1000 for nms, and 101 for nginx and clickhouse. Since the default SCCs don’t allow these UIDs, the deployment creates a custom SCC. This SCC sets the runAsUser field to allow the necessary UIDs while still complying with OpenShift’s security standards.

This deployment has been tested with OpenShift v4.13.0 Server.

If you see permission errors during deployment, your account might not have access to manage SCCs. Ask a cluster administrator for access.

To verify that the SCC was created after installing the Helm chart, run:

oc get scc nms-restricted-v2-scc --output=yaml
