AntiPattern

Dockerfile Build Contract Drift

dockerfile-contract-drift

Container build/run semantics drift when Dockerfiles, scripts, and config disagree on the build context or entry contract—e.g., ENTRYPOINT vs CMD, missing staged artifacts, ignored outputs, sandbox/syscall mismatches, or cache keys—causing builds or runtime behavior to fail.

MATCHESSolution

Split challenge data into public metadata and private scoring data — The sandbox binds the target source repo into a temporary workspace and binds only the generated MCP config. Tension: the benchmark package path with a tmpfs mount. Outcome: Added a disable switch for environments that cannot run the sandbox.

MATCHESSolution

Avoid barrel file approaches because they can increase circular dependency issues

MATCHESSolution

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

MATCHESSolution

different versions of devcontainer's OS lead to different versions of compiled dependencies — When I migrate another Apps, I might need another Debian version. Tension: this would lead to the packages land in the sam. Outcome: I figured out later.

MATCHESSolution

Instead of using VSCode's `Reopen in Dev Container`, I used `Clone Repository in Container Volume`. Tension: an isolated Docker volume with no bindings. Outcome: pnpm was then happy to use parent directories for the store.

MATCHESSolution

I tried using a `docker-compose` and it worked quite well — I still don't know how to solve this directly from the Dockerfile. Tension: the login/ endpoint does not freeze. Outcome: in fact it returns all valid tokens.

MATCHESSolution

you might need to add the path to the module like so — Dockerfile. Tension: Depending on where your Dockerfile is in your structure, which is unclear. Outcome: CMD ["uvicorn", "backend.app.main:app", "--host", "0.0.0.0", "--port", "8000"].

MATCHESSolution

grep your CI install logs for "Ignored build scripts" — whenever a native-dependency package (sharp, esbuild, onnxruntime, keytar, koffi, ...) misbehaves only in CI. Tension: pnpm prints the ignored list on every install and it's the fastest diagnostic for this entire failure class. Outcome: the fastest diagnostic for this entire failure class.

MATCHESSolution

Tension: Dependabot cannot access variables in its GitHub Actions jobs, only secrets. Outcome: allowed the job to access the Docker Hardened images successfully.

MATCHESSolution

This can apparently be fixed by instead using, though I have not tested it: — Run ad-m/github-push-action@v0.5.0. Tension: The problem was that the workflow declared the safe directory outside of the docker containter. Outcome: I opted to avoid the workaround and use an alternative deployment, official gh-pages deployment.

MATCHESSolution

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.

MATCHESSolution

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.

MATCHESSolution

secrets: | "id=pip" "src=$GITHUB_WORKSPACE/.config/pip/pip.conf" — docker/build-push-action@v6. Outcome: can you try to spilt lines into two and try once.

MATCHESSolution

GitHub Actions YAML file to pull a docker container and then run the scripts. Outcome: sudo cp $EMULATOR_CERT_PATH /usr/local/share/ca-certificates/emulator_cert.crt.

MATCHESSolution

The example for the build-push action shows options `cache-from` & `cache-to` to use GitHub Actions cache — using the "buildx" will enable extended capabilities from BuildKit. Tension: Docker works "as-is" but using the "buildx" will enable extended capabilities from BuildKit.

MATCHESSolution

Use ubuntu-latest for Docker builds instead of macos-latest

MATCHESSolution

use Docker build args, it is `ARG` in the Dockerfile — parameter (`FROM_TAG`) build value can be passed to `docker build`. Tension: The Dockerfile does not need to be changed any longer. Outcome: docker build --build-arg="FROM_TAG=${imageID}" --tag "abc:${newImageID}" .

MATCHESSolution

We can prevent a job run with an empty matrix — For the `docker` job. Tension: the docker job starts even when all outputs from the changes job are false.

MATCHESSolution

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.

MATCHESSolution

Create a custom GitHub Action (instead of using the generic containerized action) with a custom entrypoint script that traps SIGINT/SIGTERM and runs the required teardown commands before exiting. Ensure the entry process handles the signals so the container terminates gracefully.

MATCHESSolution

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

MATCHESSolution

You have to change the docker entrypoint command like below to use a custom `vault.hcl` file. — Example `docker-compose.yaml` file. Tension: it just always seems to want to find a local.json file. Outcome: entrypoint: vault server -config=/vault/vault.hcl.

MATCHESSolution

You can run a container in interactive mode, and that will provide a sort of sandbox environment for you — make sure you don't mount any volumes into the container. Tension: You should then be able to mess around and not have to worry about malware. Outcome: docker run -it container.

MATCHESSolution

it is preferable to overwrite it on a per-container basis. Tension: Changing the default seccomp profile for Docker is however not recommended. Outcome: both options should achieve the same result.

MATCHESSolution

Pin the build to a stable Node.js version (e.g., change the pipeline Docker image from `node` to `node:lts`) and rebuild.

MATCHESSolution

Alternatives are listed there — From https://hub.docker.com/_/openjdk :. Tension: you will have to update your build. Outcome: use one of them.

MATCHESSolution

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.

MATCHESSolution

FROM mcr.microsoft.com/playwright:bionic — within the service and build key. Outcome: specify the Docker image in the docker-compose file in the service section.

MATCHESSolution

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.

MATCHESSolution

Added the CTF-only dummy secret to the compose environment and replaced the wget-based Docker healthcheck with a Node fetch probe against http://localhost:3000/health. Tension: the API served /health but Docker still reported unhealthy. Outcome: Recreated the API container after the compose changes.
