To regenerate this document, from the root of this chart directory run:
```shell
docker run --rm --volume "$(pwd):/helm-docs" -u $(id -u) jnorwood/helm-docs:latest
```

## Installation

```console
helm repo add argo https://argoproj.github.io/argo-helm
helm install argocd-image-updater argo/argocd-image-updater
```

You will also need to run through the [secret setup documentation](https://argocd-image-updater.readthedocs.io/en/stable/install/start/#connect-using-argo-cd-api-server) so ArgoCD ImageUpdater can talk to the ArgoCD API (until its automated in this chart).

## Prerequisites

* Helm v3.0.0+

## Configuration options

In order for your deployment of ArgoCD Image Updater to be successful, you will need to make sure you set the correct configuration options described in detail on the [argocd-image-updater flags page](https://argocd-image-updater.readthedocs.io/en/stable/install/running/#flags).

All of the `argocd-` prefixed flags, which tell `argocd-image-updater` how your ArgoCD instance is setup, are set in the `config.argocd` values block. For instance:

```yaml
config:
  argocd:
    grpcWeb: false
    serverAddress: "http://argocd.argo"
    insecure: true
    plaintext: true
```

Any additional arguments mentioned on the [argocd-image-updater flags page](https://argocd-image-updater.readthedocs.io/en/stable/install/running/#flags) can be configured using the `extraArgs` value, like so.

### ArgoCD API key

If you are unable to install Argo CD Image Updater into the same Kubernetes cluster you might configure it to use API of your Argo CD installation.
Please also read [the documentation](https://argocd-image-updater.readthedocs.io/en/stable/configuration/registries/).

```yaml
config:
  argocd:
    token: <your_secret_here>
```

If you specify a token value the secret will be created.

### Registries

ArgoCD Image Updater natively supports the following registries (as mentioned in [the documentation](https://argocd-image-updater.readthedocs.io/en/stable/configuration/registries/)):

- Docker Hub
- Google Container Registry
- RedHat Quay
- GitHub Container Registry
- GitHub Docker Packages

If you need support for ECR, you can reference [this issue](https://github.com/argoproj-labs/argocd-image-updater/issues/112) for configuration. You can use the `authScripts` values to configure the scripts that are needed to authenticate with ECR.

The `config.registries` value can be used exactly as it looks in the documentation as it gets dumped directly into a configmap in this chart.
