 `composetest_db`. If the Compose file specifies an
 [image](/compose/compose-file/index.md#image) name, the image will be
 tagged with that name, substituting any variables beforehand. See [variable

 If you change a service's Dockerfile or the contents of its
 build directory, run `docker-compose build` to rebuild it.
