The behaviour you’re seeing is expected, because even though the Docker image has changed, your deployment YAML file has not. This means that the version of that file in k8s is the same as that file in git, so it won’t signal to ArgoCD that there’s a delta. What you need to do is increment the image version, which you should always do anyway, because using “latest” is considered bad practice, as it gives you no indication as to what is in prod.
