# build ``` Usage: build [options] [SERVICE...] Options: --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 --pull Always attempt to pull a newer version of the image. ``` 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, run `docker-compose build` to rebuild it.
