TL;DR

helm install my-release oci://registry-1.docker.io/bitnamicharts/nginx-ingress-controller

Introduction

Bitnami charts for Helm are carefully engineered, actively maintained and are the quickest and easiest way to deploy containers on a Kubernetes cluster that are ready to handle production workloads.

This chart bootstraps a ingress-nginx deployment on a Kubernetes cluster using the Helm package manager.

Bitnami charts can be used with Kubeapps for deployment and management of Helm Charts in clusters.

Prerequisites

• Kubernetes 1.19+
• Helm 3.2.0+

Installing the Chart

To install the chart with the release name my-release:

helm install my-release oci://registry-1.docker.io/bitnamicharts/nginx-ingress-controller

These commands deploy nginx-ingress-controller on the Kubernetes cluster in the default configuration.

Tip: List all releases using helm list

Uninstalling the Chart

To uninstall/delete the my-release deployment:

helm delete my-release

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

Specify each parameter using the --set key=value[,key=value] argument to helm install. For example,

helm install my-release \
    --set image.pullPolicy=Always \
    oci://registry-1.docker.io/bitnamicharts/nginx-ingress-controller

The above command sets the image.pullPolicy to Always.

Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,

helm install my-release -f values.yaml oci://registry-1.docker.io/bitnamicharts/nginx-ingress-controller

Tip: You can use the default values.yaml

Configuration and installation details

Rolling VS Immutable tags

It is strongly recommended to use immutable tags in a production environment. This ensures your deployment does not change automatically if the same tag is updated with a different image.

Bitnami will release a new chart updating its containers if a new version of the main container, significant changes, or critical vulnerabilities exist.

Sidecars and Init Containers

If you have a need for additional containers to run within the same pod as the NGINX Ingress Controller (e.g. an additional metrics or logging exporter), you can do so via the sidecars config parameter. Simply define your container according to the Kubernetes container spec.

sidecars:
  - name: your-image-name
    image: your-image
    imagePullPolicy: Always
    ports:
      - name: portname
       containerPort: 1234

Similarly, you can add extra init containers using the initContainers parameter.

initContainers:
  - name: your-image-name
    image: your-image
    imagePullPolicy: Always
    ports:
      - name: portname
        containerPort: 1234

Deploying extra resources

There are cases where you may want to deploy extra objects, such a ConfigMap containing your app's configuration or some extra deployment with a micro service used by your app. For covering this case, the chart allows adding the full specification of other objects using the extraDeploy parameter.

Setting Pod's affinity

This chart allows you to set your custom affinity using the affinity parameter. Find more information about Pod's affinity in the kubernetes documentation.

As an alternative, you can use of the preset configurations for pod affinity, pod anti-affinity, and node affinity available at the bitnami/common chart. To do so, set the podAffinityPreset, podAntiAffinityPreset, or nodeAffinityPreset parameters.

Troubleshooting

Notable changes

5.3.0

In this version you can indicate the key to download the GeoLite2 databases using the parameter maxmindLicenseKey.

Upgrading

To 9.0.0

• Configuration for routing Ingress resources with custom kubernetes.io/ingress.class annotation is changed in favor of IngressClass resource required in NGINX Ingress Controller 1.x
  • ingressClass parameter is removed and replaced with ingressClassResource.* parameters
  • ingressClassResource.* parameters configure IngressClass resource only
  • To configure routing for Ingress using custom kubernetes.io/ingress.class annotation define extraArgs.ingress-class parameter with the annotation value

Consequences:

• Backwards compatibility is not guaranteed. Uninstall & install the chart again to obtain the latest version.

To 7.0.0

• Chart labels were adapted to follow the Helm charts standard labels.
• Several parameters were renamed or disappeared in favor of new ones on this major version. These are a few examples:
  • *.securityContext paramateres are deprecated in favor of *.containerSecurityContext ones.
  • *.minAvailable paramateres are deprecated in favor of *.pdb.minAvailable ones.
  • extraContainers paramatere is deprecated in favor of sidecars.
• This version also introduces bitnami/common, a library chart as a dependency. More documentation about this new utility could be found here. Please, make sure that you have updated the chart dependencies before executing any upgrade.

Consequences:

• Backwards compatibility is not guaranteed. Uninstall & install the chart again to obtain the latest version.

To 6.0.0

On November 13, 2020, Helm v2 support was formally finished, this major version is the result of the required changes applied to the Helm Chart to be able to incorporate the different features added in Helm v3 and to be consistent with the Helm project itself regarding the Helm v2 EOL.

What changes were introduced in this major version?

• Previous versions of this Helm Chart use apiVersion: v1 (installable by both Helm 2 and 3), this Helm Chart was updated to apiVersion: v2 (installable by Helm 3 only). Here you can find more information about the apiVersion field.
• The different fields present in the Chart.yaml file has been ordered alphabetically in a homogeneous way for all the Bitnami Helm Charts

Considerations when upgrading to this version

• If you want to upgrade to this version from a previous one installed with Helm v3, you shouldn't face any issues
• If you want to upgrade to this version using Helm v2, this scenario is not supported as this version doesn't support Helm v2 anymore
• If you installed the previous version with Helm v2 and wants to upgrade to this version with Helm v3, please refer to the official Helm documentation about migrating from Helm v2 to v3

To 1.0.0

Backwards compatibility is not guaranteed unless you modify the labels used on the chart's deployments. Use the workaround below to upgrade from versions previous to 1.0.0. The following example assumes that the release name is nginx-ingress-controller:

$ kubectl patch deployment nginx-ingress-controller-default-backend --type=json -p='[{"op": "remove", "path": "/spec/selector/matchLabels/chart"}]'
# If using deployments
$ kubectl patch deployment nginx-ingress-controller --type=json -p='[{"op": "remove", "path": "/spec/selector/matchLabels/chart"}]'
# If using daemonsets
$ kubectl patch daemonset nginx-ingress-controller --type=json -p='[{"op": "remove", "path": "/spec/selector/matchLabels/chart"}]'
