I'm currently working on a Docker project for my Raspberry Pi, but I'm developing it on Windows using WSL. I have a Docker Compose file that contains all my build and run parameters. However, when I pull the image from my Docker registry on the Raspberry Pi, I don't have the Docker Compose file there, so I have to run it manually with commands like: `docker run param1 param2 param3 testRegistry/dockertest`. I could recreate it each time, but I'd prefer a way to automatically pull any updates to the Docker Compose file along with the image, so that I can just run `docker compose up` without manual intervention. Any tips on how to handle this efficiently would be greatly appreciated, as I'm still getting accustomed to Docker.

You might want to use a version control system like Git with something like Forgejo or Gitea. You can commit your Docker Compose file along with your build files, and use CI/CD runners to build the image and upload it to your registry. Then, you can simply `git pull` the updated Compose file on your Raspberry Pi and execute it right there. Plus, you can even mount storage from your Raspberry Pi into your WSL environment to directly use that file with a file watcher like `fsnotify`. It's a streamlined approach!
Just a heads-up, you can do similar setups with GitLab, though I wouldn't recommend running GitLab on a Raspberry Pi—it might be too much for it!
Definitely! The runner with Docker buildx is the way to go. It simplifies the whole process. I set it up for my project and now I just push the latest code and hit build. It takes care of everything automatically.
