how to save the logs for docker-compose up -d --build

Question

The logs are printed on the console when I do docker-compose up -d --build, how can I have them saved to a file so I can go through the logs?

This can be achieved using docker-compose build and the --progress flag and specifying one of the following options: auto, tty, plain, or quiet (default "auto")

So to persist the logs in your terminal you would build with:

docker-compose build --progress plain

See --help:

 $ docker-compose build --help

Usage:  docker compose build [OPTIONS] [SERVICE...]

Build or rebuild services

Options:
      --build-arg stringArray   Set build-time variables for services.
      --no-cache                Do not use cache when building the image
      --progress string         Set type of progress output (auto, tty, plain, quiet) (default "auto")
      --pull                    Always attempt to pull a newer version of the image.
  -q, --quiet                   Don't print anything to STDOUT
      --ssh string              Set SSH authentications used when building service images. (use
                                'default' for using your default SSH Agent)
