## TL;DR

```console
helm install my-release oci://registry-1.docker.io/bitnamicharts/external-dns
```

Looking to use ExternalDNS in production? Try [VMware Tanzu Application Catalog](https://bitnami.com/enterprise), the enterprise edition of Bitnami Application Catalog.

## Introduction

This chart bootstraps a [ExternalDNS](https://github.com/bitnami/containers/tree/main/bitnami/external-dns) deployment on a [Kubernetes](https://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.

Bitnami charts can be used with [Kubeapps](https://kubeapps.dev/) for deployment and management of Helm Charts in clusters.

## Prerequisites

- Kubernetes 1.23+
- Helm 3.8.0+

## Installing the Chart

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

```console
helm install my-release oci://REGISTRY_NAME/REPOSITORY_NAME/external-dns
```

> Note: You need to substitute the placeholders `REGISTRY_NAME` and `REPOSITORY_NAME` with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use `REGISTRY_NAME=registry-1.docker.io` and `REPOSITORY_NAME=bitnamicharts`.

The command deploys ExternalDNS on the Kubernetes cluster in the default configuration. The [Parameters](#parameters) section lists the parameters that can be configured during installation.

> **Tip**: List all releases using `helm list`

## Configuration and installation details

### Resource requests and limits

Bitnami charts allow setting resource requests and limits for all containers inside the chart deployment. These are inside the `resources` value (check parameter table). Setting requests is essential for production workloads and these should be adapted to your specific use case.

To make this process easier, the chart contains the `resourcesPreset` values, which automatically sets the `resources` section according to different presets. Check these presets in [the bitnami/common chart](https://github.com/bitnami/charts/blob/main/bitnami/common/templates/_resources.tpl#L15). However, in production workloads using `resourcePreset` is discouraged as it may not fully adapt to your specific needs. Find more information on container resource management in the [official Kubernetes documentation](https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/).

### [Rolling VS Immutable tags](https://docs.vmware.com/en/VMware-Tanzu-Application-Catalog/services/tutorials/GUID-understand-rolling-tags-containers-index.html)

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.

### 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](https://kubernetes.io/docs/concepts/configuration/assign-pod-node/#affinity-and-anti-affinity).

As an alternative, you can use of the preset configurations for pod affinity, pod anti-affinity, and node affinity available at the [bitnami/common](https://github.com/bitnami/charts/tree/main/bitnami/common#affinities) chart. To do so, set the `podAffinityPreset`, `podAntiAffinityPreset`, or `nodeAffinityPreset` parameters.

### Using IRSA

If you are deploying to AWS EKS and you want to leverage [IRSA](https://docs.aws.amazon.com/eks/latest/userguide/iam-roles-for-service-accounts.html). You will need to override `fsGroup` and `runAsUser` with `65534`(nfsnobody) and `0` respectively. Otherwise service account token will not be properly mounted.
You can use the following arguments:

```console
--set podSecurityContext.fsGroup=65534 --set podSecurityContext.runAsUser=0
```

## Tutorials

Find information about the requirements for each DNS provider on the link below:

- [ExternalDNS Tutorials](https://github.com/kubernetes-sigs/external-dns/tree/master/docs/tutorials)

For instance, to install ExternalDNS on AWS, you need to:

- Provide the K8s worker node which runs the cluster autoscaler with a minimum IAM policy (check [IAM permissions docs](https://github.com/kubernetes-sigs/external-dns/blob/master/docs/tutorials/aws.md#iam-permissions) for more information).
- Setup a hosted zone on Route53 and annotate the Hosted Zone ID and its associated "nameservers" as described on [these docs](https://github.com/kubernetes-sigs/external-dns/blob/master/docs/tutorials/aws.md#set-up-a-hosted-zone).
- Install ExternalDNS chart using the command below:

> Note: replace the placeholder HOSTED_ZONE_IDENTIFIER and HOSTED_ZONE_NAME, with your hosted zoned identifier and name, respectively.

```console
helm install my-release \
  --set provider=aws \
  --set aws.zoneType=public \
  --set txtOwnerId=HOSTED_ZONE_IDENTIFIER \
  --set domainFilters[0]=HOSTED_ZONE_NAME \
  oci://REGISTRY_NAME/REPOSITORY_NAME/external-dns
```

> Note: You need to substitute the placeholders `REGISTRY_NAME` and `REPOSITORY_NAME` with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use `REGISTRY_NAME=registry-1.docker.io` and `REPOSITORY_NAME=bitnamicharts`.

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

```console
helm install my-release \
  --set provider=aws oci://REGISTRY_NAME/REPOSITORY_NAME/external-dns
```

> Note: You need to substitute the placeholders `REGISTRY_NAME` and `REPOSITORY_NAME` with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use `REGISTRY_NAME=registry-1.docker.io` and `REPOSITORY_NAME=bitnamicharts`.

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

```console
helm install my-release -f values.yaml oci://REGISTRY_NAME/REPOSITORY_NAME/external-dns
```

> Note: You need to substitute the placeholders `REGISTRY_NAME` and `REPOSITORY_NAME` with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use `REGISTRY_NAME=registry-1.docker.io` and `REPOSITORY_NAME=bitnamicharts`.
> **Tip**: You can use the default [values.yaml](https://github.com/bitnami/charts/tree/main/bitnami/external-dns/values.yaml)

## Upgrading

### To 7.0.0

This major bump changes the following security defaults:

- `runAsGroup` is changed from `0` to `1001`
- `readOnlyRootFilesystem` is set to `true`
- `resourcesPreset` is changed from `none` to the minimum size working in our test suites (NOTE: `resourcesPreset` is not meant for production usage, but `resources` adapted to your use case).
- `global.compatibility.openshift.adaptSecurityContext` is changed from `disabled` to `auto`.

This could potentially break any customization or init scripts used in your deployment. If this is the case, change the default values to the previous ones.

### To 6.0.0

Some of the chart values were changed to adapt to the latest Bitnami standards. More specifically:

- `containerPort` was changed to `containerPorts.http`
- `service.port` was changed to `service.ports.http`

No issues should be expected when upgrading.

### To 5.0.0

The CRD was updated according to the latest changes in the upstream project. As a consequence, the CRD API version was moved from `apiextensions.k8s.io/v1beta1` to `apiextensions.k8s.io/v1`. If you deployed the Helm Chart using `crd.create=true` you need to manually delete the old CRD before upgrading the release.

```console
kubectl delete crd dnsendpoints.externaldns.k8s.io
helm upgrade my-release -f my-values.yaml
```

### To 4.3.0

This version also introduces `bitnami/common`, a [library chart](https://helm.sh/docs/topics/library_charts/#helm) as a dependency. More documentation about this new utility could be found [here](https://github.com/bitnami/charts/tree/main/bitnami/common#bitnami-common-library-chart). Please, make sure that you have updated thechart dependencies before executing any upgrade.

### To 4.0.0

[On November 13, 2020, Helm v2 support was formally finished](https://github.com/helm/charts#status-of-the-project), 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](https://helm.sh/docs/topics/charts/#the-apiversion-field) 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](https://helm.sh/docs/topics/v2_v3_migration/#migration-use-cases) about migrating from Helm v2 to v3

- <https://helm.sh/blog/migrate-from-helm-v2-to-helm-v3/>

### To 3.0.0

- The parameters below are renamed:
  - `rbac.serviceAccountCreate` -> `serviceAccount.create`
  - `rbac.serviceAccountName` -> `serviceAccount.name`
  - `rbac.serviceAccountAnnotations` -> `serviceAccount.annotations`
- It is now possible to create serviceAccount, clusterRole and clusterRoleBinding manually and give the serviceAccount to the chart.

### To 2.0.0

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 `my-release`:

```console
kubectl delete deployment my-release-external-dns
helm upgrade my-release oci://REGISTRY_NAME/REPOSITORY_NAME/external-dns
```

> Note: You need to substitute the placeholders `REGISTRY_NAME` and `REPOSITORY_NAME` with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use `REGISTRY_NAME=registry-1.docker.io` and `REPOSITORY_NAME=bitnamicharts`.

Other mayor changes included in this major version are:

- Default image changes from `registry.opensource.zalan.do/teapot/external-dns` to `bitnami/external-dns`.
- The parameters below are renamed:
  - `aws.secretKey` -> `aws.credentials.secretKey`
  - `aws.accessKey` -> `aws.credentials.accessKey`
  - `aws.credentialsPath` -> `aws.credentials.mountPath`
  - `designate.customCA.directory` -> `designate.customCA.mountPath`
- Support to Prometheus metrics is added.
