Trying help commands for subcommands
Even you can try help for docker subcommands also
$ docker-compose build --help Build or rebuild services. Services are built once and then tagged as `project_service`, e.g. `composetest_db`. If you change a service's `Dockerfile` or the contents of its build directory, you can run `docker-compose build` to rebuild it. Usage: build [options] [--build-arg key=val...] [SERVICE...] Options: --compress Compress the build context using gzip. --force-rm Always remove intermediate containers. --no-cache Do not use cache when building the image. --pull Always attempt to pull a newer version of the image. -m, --memory MEM Sets memory limit for the build container. --build-arg key=val Set build-time variables for services. --parallel Build images in parallel.
