# build
```
Usage: build [options] [SERVICE...]
Options:
--no-cache Do not use cache when building 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.
