Propagating New Image Versions in Argo CD 🔗

Argo CD Image Updater supports two write-back methods for propagating new image versions to Argo CD.

argocd: Directly modifies the Argo CD application resource via Kubernetes or the Argo CD API, depending on the configuration.
git: Creates a Git commit in the application’s repository with the updated image information.

The write-back method and its configuration are set per application, with further configuration options available depending on the method used.

In this microcourse, the examples are applied using the argocd update method, which is the default update method and does not need further configuration. For production environments, it is recommended to use the git update method to persist the changes made by Argo CD Image Updater in your git repository.
