Shrink A Node Image With Multi-Stage Builds
Apply a worked Docker pattern for multi-stage build separation.
A service works only after Iris runs three manual shell commands inside the container. The team needs the fix in source control before the release branch closes. Move repeatable setup into the image, move deploy-specific values into runtime config, and prove the result with one run command. The common trap is to make the current container healthy while leaving the next container broken. Step 1 List the manual commands and mark each as build-time dependency, runtime config, or one-off data. This prevents every command from being shoved into the Dockerfile.
