Using ArgoCD Image updater with Google Artifact Registry
What
ArgoCD Image updater is a cool tool that allows you to update Images for containers, provided you use Argo CD
The issue
From what I could see, argocd image updater needs you to provide credentials to the cli tool, to get images.
If you are using Google Artifact registry (Officially not supported, but works anyway) - You need to supply credentials as the application does not use your local creds.
Export Credentials
We will export the credentials to an Environment Variable, as this seems to be the only way that it picks them up
This will run the command gcloud auth print-access-token first (as it's in parentheses, remember PEMDAS) then save its value as text.
Optionally, check what it looks like
Should return something like the below
