You can use Docker Compose binary,
docker-compose [-f <arg>...] [options] [COMMAND] [ARGS...], to build and manage multiple services in Docker containers.
-fto specify name and path of one or more Compose files
-f flag to specify the location of a Compose configuration file.
You can supply multiple
-f configuration files. When you supply multiple files, Compose combines them into a single configuration. Compose builds the configuration in the order you supply the files. Subsequent files override and add to their predecessors.
For example, consider this command line:
$ docker-compose -f docker-compose.yml -f docker-compose.admin.yml run backup_db
docker-compose.yml file might specify a
webapp: image: examples/web ports: - "8000:8000" volumes: - "/data"
docker-compose.admin.yml also specifies this same service, any matching fields will override the previous file. New values, add to the
webapp service configuration.
webapp: build: . environment: - DEBUG=1
- (dash) as the filename to read the configuration from
stdin is used all paths in the configuration are relative to the current working directory.
-f flag is optional. If you don’t provide this flag on the command line, Compose traverses the working directory and its parent directories looking for a
docker-compose.yml and a
docker-compose.override.yml file. You must supply at least the
docker-compose.yml file. If both files are present on the same directory level, Compose combines the two files into a single configuration.
The configuration in the
docker-compose.override.yml file is applied over and in addition to the values in the
You can use
-f flag to specify a path to Compose file that is not located in the current directory, either from the command line or by setting up a COMPOSE_FILE environment variable in your shell or in an environment file.
For an example of using the
-f option at the command line, suppose you are running the Compose Rails sample, and have a
docker-compose.yml file in a directory called
sandbox/rails. You can use a command like docker-compose pull to get the postgress image for the
db service from anywhere by using the
-f flag as follows:
docker-compose -f ~/sandbox/rails/docker-compose.yml pull db
Here’s the full example:
$ docker-compose -f ~/sandbox/rails/docker-compose.yml pull db Pulling db (postgres:latest)... latest: Pulling from library/postgres ef0380f84d05: Pull complete 50cf91dc1db8: Pull complete d3add4cd115c: Pull complete 467830d8a616: Pull complete 089b9db7dc57: Pull complete 6fba0a36935c: Pull complete 81ef0e73c953: Pull complete 338a6c4894dc: Pull complete 15853f32f67c: Pull complete 044c83d92898: Pull complete 17301519f133: Pull complete dcca70822752: Pull complete cecf11b8ccf3: Pull complete Digest: sha256:1364924c753d5ff7e2260cd34dc4ba05ebd40ee8193391220be0f9901d4e1651 Status: Downloaded newer image for postgres:latest
-pto specify a project name
Each configuration has a project name. If you supply a
-p flag, you can specify a project name. If you don’t specify the flag, Compose uses the current directory name. See also the COMPOSE_PROJECT_NAME environment variable.
You can set environment variables for various
docker-compose options, including the
Also, you can set some of these variables in an environment file.
