Walkthrough
The changes introduce a new job in the GitHub Actions workflow for Docker setup, transitioning the application from a MongoDB-based Docker image to a Node.js-based image in the Dockerfile. The
docker-compose.ymlfile is updated to remove the old MongoDB service and add a new service for the application, namedopenwf, which connects to a simplified MongoDB service. Additionally, a new entrypoint script is created to handle the container's initialization and configuration. A.dockerignorefile is also added to specify files and directories to be ignored during the Docker build process. The.gitignorefile is updated to include new paths, and an example environment variable file is removed.Changes

Well, the thing is, we don't want to distribute anything that could potentially be an issue for the respective rights holders, hence why the supplemental data is not provided in the repository here.
I don't know how great it is if you provide a script that just fetches that data anyway — and then you also attempt to publish it? This may be a severe conflict for this project and a good reason to completely eliminate Docker from it if this is not handled with more care.

Are build config files themselves a violation of copyright? I was under the impression that only the binary cache was actionable.

Action Required: Add a Checkout Step to the Workflow
The build and push step is missing a checkout step. Please add a checkout step before the build and push step to ensure the repository code is available for the Docker build process.
🔗 Analysis chain
LGTM with a minor concern: Build and push configuration.
The build and push step is well-configured:
docker/build-push-action.However, there's one potential issue:
There's no explicit checkout step before this build step. While some actions automatically check out the repository, it's generally safer to include an explicit checkout step to ensure the correct code is available for the build context.
Consider adding a checkout step at the beginning of the job:
This will ensure that the correct code is available for the Docker build process.

It is sometimes helpful, however not for the scope of this PR. Please review.
Well, from what I can tell, your env vars like
APP_INFINITE_RESOURCESare hooked up to nothing.Environment variables are expanded on startup and a config.json file is created from them. The image is built with a set of default environment variables which can be overridden by the user, for example in docker-compose.yml.
You will still need to remove the Github workflow, tho, it's not going to work in this repository.
Why? It will build images on commit to main branch and push them to the GitHub Container Registry, available to users. These images just hold a copy of the source code, nothing more.
Nevermind, I saw it was being skipped and thought it was broken. Could you move it into its own workflow file so that you can make it
on: push: ["main"]instead of this hacky approach?You're letting it run on
pull_requestis that intended?It was not, apologies.
Looks fine to me now, but for posterity's sake, is there a way the "data" folder can be renamed? I can imagine such a generic name being in the .gitignore could be a serious headache in the future.
/data was added to gitignore for convenience, so that it wouldn't show up as unstaged during development/use. However renaming it is probably a good idea.
