Custom Argo CD Installation

Argo CD is installed using a Helm Chart. You can specify the Chart version with the --argocd-chart-version option. It defaults to the latest version.

You can modify the Argo CD Helm Chart installation by providing the tool with a values.yaml file and mounting it in the argocd-config folder within the container. Check out all the available values in the Argo CD Helm Chart.

Example:

Here we set configs.cm."kustomize.buildOptions" in the Chart.
