Container Startup Command Mismatch

entrypoint-cmd-mismatch-on-container-start

Container startup fails because image ENTRYPOINT/CMD expectations diverge from how the runner supplies commands and filesystem mounts, leading to missing binaries, ignored config files, and tool/version conflicts when local files or nested virtualization assumptions are copied in.

Pin the provider backend command to the absolute standalone CLI path with a persistent service startup patcher, then restart the gateway and verify the child process command path and transcript version.

MATCHESSolution

`omnimart@0.1.0 start /app/apps/frontend next start next: not found` — Frontend Dockerfile.

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

Use --platform=linux/amd64 in the follow-up images too

MATCHESSolution

post-start failures. Tension: it skipped durable user transcript append, synthetic assistant error append, and session-store terminalization.

MATCHESSolution

I change config.yml and changed system.url-prefix: 'https:/IP' to system.url-prefix: 'https:/sentry.domain.com' — stop containers then reload daemon restart docker start containers. Tension: Origin checking failed - https://sentry-domain.com does not match any trusted origins. Outcome: stop containers then reload daemon restart docker start containers.

MATCHESSolution

Then I set the docker env in the /.docker/config.json — self hosted guide. Tension: but I can't understand where and if I had to put it. Outcome: restart docker.

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

Use python -m uvicorn with the correct module path in ENTRYPOINT

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

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

MATCHESSolution

Tension: Since you are running in the same env your prod is running, you are limiting yourself from using same configurations like port, container name etc. Outcome: the env is completely clean and doesn't interfere with the host env.

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

Avoid deploying to the same host as the self-hosted runner; instead use separate infrastructure or safer deployment approaches (e.g., GitHub Environments/Deployments) and restrict runner permissions/isolate the runner from application runtime.

MATCHESSolution

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

MATCHESSolution

Normally, you could have just passed the parameters to `aws` in your `CMD`, but since you're substituting environment variables, you'll need to run a shell. — you'll need to run a shell. Tension: since you're substituting environment variables. Outcome: ENTRYPOINT sh -c "aws s3 sync /build s3://${BUCKET_NAME} --delete".

MATCHESSolution

FROM postgres:16 — docker-compose.build.yml. Tension: The data directory was initialized by PostgreSQL version 16. Outcome: docker-compose -f docker-compose.build.yml up --build --remove-orphans.

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

Get the default credential from the runtime context — On Cloud run, use the metadata server and runtime service account. Tension: When building a Docker image, the creds.json file isn't included, leading to failures in authentication.

MATCHESSolution

On your local machine, use your own credential directly — On your local machine, use your own credential directly. Tension: If you use your container locally, you can read my article to use your own credential in the local container runtime context.

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

Use a newer runtime base image such as mcr.microsoft.com/dotnet/aspnet:6.0-alpine for the final stage

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

As a workaround, you may consider running `grype` as the `root` user — please test it on an image that wasn't previously pushed to the Docker Hub. Outcome: docker run --rm --name grype -u 0 -v /var/run/docker.sock:/var/run/docker.sock anchore/grype:latest --only-fixed mirekphd/ml-cache:20230731.

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

Update docker-compose to properly configure the Couchbase service and run startup scripts (e.g., setup-couchbase.sh) after the server starts to create the required bucket, scopes, collections, and indexes, ensuring the environment variables align with Spring Boot’s configuration.

MATCHESSolution

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.

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.
