DESCRIBESQuestion

Docker multi-stage build cache invalidated on every COPY even when files unchanged

CAUSED_BYRootCause

Your `.dockerignore` is excluding the `dist` folder — Dockerize this? Tension: the built files never make it into the Docker image. Outcome: Missing build output.

FIXED_BYSolution

The built files never make it into the Docker image — Dockerize this? Tension: Your `.dockerignore` is excluding the `dist` folder.

FIXED_BYSolution

installing the obfuscator changes less often than building your project — Change the sequence so you have a container ready to build your project then obfuscate it. Tension: These are the last steps in the Dockerfile. Outcome: juggle commands that reveal same results to execute first.

FIXED_BYSolution

If you don't want to create a file manually, you can pass the content directly: — docker/build-push-action@v6. Tension: the secret is passed as a variable inside the container. Outcome: Use `secrets:` to Pass File Content Directly.

FIXED_BYSolution

You need to remove that from the Dockerfile — The FROM line specifies `--platform=$BUILDPLATFORM`. Tension: stop building images with a platform that doesn't match the contents of the filesystem layers. Outcome: to stop building images with a platform that doesn't match the contents of the filesystem layers.

FIXED_BYSolution

Use either Dockerfile plugin installation or ENABLE_BUILT_IN_PLUGINS, but do not mix both

FIXED_BYSolution

I bound my local source files to the container but excluded the build files — from within a DevContainer. Tension: hot reload started working correctly. Outcome: hot reload started working correctly.

FIXED_BYSolution

check the container logs — When working with Docker and Django it's quite common to get things into a state where the container keeps restarting / won't really start. Tension: This usually indicates a problem in Django and the logs shows us what's wrong with it. Outcome: one will get a more specific error.

FIXED_BYSolution

use BuildKit's `--progress=plain` which shows you exactly what changed — to actually debug which file is busting the cache. Outcome: add these to `.dockerignore` aggressively.
