ArgoCD imagePullSecrets

Note on image pulling in ArgoCD from private gitlab repo.

It’s Private Repo so you must use deploy token. Add Deploy token in your gitlab project then you can use deploy token to pull image from ArgoCD.

First, add Deploy Token. Select Setting > Repository

Expand Deploy tokens and create deploy token.

Fill in Name, Username and check read_repository and read_registry.

You will get a new token.

Next, Add a secret to your K8S.

kubectl create secret docker-registry regcred-frontend \
  --namespace=test-frontend \
  --docker-server=https://registry.gitlab.com \
  --docker-username=dev01 \
  --docker-password=82xxW78WJscyMbPsYFhe \
  --docker-email=dev01@gmail.com

Then, Your deployment.yml will be something like this.

  name: frontend-web
  labels:
    app: frontend-web
