CI/CD pipeline for microservice.

Hi Saurabh, I’d build the Docker image in the CI/build pipeline, push it to a registry like Azure Container Registry, and then let the release or deployment stage promote that same image through UAT and production. Try not to rebuild the image for each environment, because then you are not testing and releasing the exact same artifact. For tags, I’d use an immutable tag such as the build ID, commit SHA, or release version, and optionally also maintain a friendly tag like latest only for convenience. Production should deploy a fixed version tag, not latest.
