Commands I use frequently:

If you've updated your code, you can do the build and reload in a single step with:

docker compose up --detach --build {service-name}
Restart a single container with docker-compose:

docker compose restart worker
Run interactive shell to explore containers:

docker run -it image_name sh
Or following for images with an entrypoint

docker run -it --entrypoint sh image_name
If you want to see how the image was build, meaning the steps in its dockerfile, you can:

docker image history --no-trunc image_name > image_history
