argocd-image-updater

A Helm chart for Argo CD Image Updater, a tool to automatically update the container images of Kubernetes workloads which are managed by Argo CD

To regenerate this document, from the root of this chart directory run:

docker run --rm --volume "$(pwd):/helm-docs" -u $(id -u) jnorwood/helm-docs:latest

Installation

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 so ArgoCD ImageUpdater can talk to the ArgoCD API (until its automated in this chart).

TODO

• Automate setting up the ArgoCD API Authentication user/secret using a Helm Hook or something.

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.

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:

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

Any additional arguments mentioned on the argocd-image-updater flags page can be configured using the extraArgs value, like so.

Registries

ArgoCD Image Updater natively supports the following registries (as mentioned in the documentation):

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

If you need support for ECR, you can reference this issue 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.
