command: docker compose
short: Docker Compose
long: |-
    You can use the compose subcommand, `docker compose [-f <arg>...] [options] [COMMAND] [ARGS...]`, to build and manage
    multiple services in Docker containers.

    ### Use `-f` to specify the name and path of one or more Compose files
    Use the `-f` flag to specify the location of a Compose configuration file.

    #### Specifying multiple Compose files
    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:

    ```console
    $ docker compose -f docker-compose.yml -f docker-compose.admin.yml run backup_db
    ```

    The `docker-compose.yml` file might specify a `webapp` service.

    ```yaml
    services:
      webapp:
        image: examples/web
        ports:
          - "8000:8000"
        volumes:
          - "/data"
    ```
    If the `docker-compose.admin.yml` also specifies this same service, any matching fields override the previous file.
    New values, add to the `webapp` service configuration.

    ```yaml
    services:
      webapp:
        build: .
        environment:
          - DEBUG=1
    ```

    When you use multiple Compose files, all paths in the files are relative to the first configuration file specified
    with `-f`. You can use the `--project-directory` option to override this base path.

    Use a `-f` with `-` (dash) as the filename to read the configuration from stdin. When stdin is used all paths in the
    configuration are relative to the current working directory.

    The `-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 `compose.yaml` or `docker-compose.yaml` file.

    #### Specifying a path to a single Compose file
    You can use the `-f` flag to specify a path to a 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 `compose.yaml` file in a directory called `sandbox/rails`. You can use a command like `docker compose pull` to
    get the postgres image for the db service from anywhere by using the `-f` flag as follows:

    ```console
    $ docker compose -f ~/sandbox/rails/compose.yaml pull db
    ```

    ### Use `-p` to specify a project name

    Each configuration has a project name. Compose sets the project name using
    the following mechanisms, in order of precedence:
    - The `-p` command line flag
    - The `COMPOSE_PROJECT_NAME` environment variable
    - The top level `name:` variable from the config file (or the last `name:`
    from a series of config files specified using `-f`)
    - The `basename` of the project directory containing the config file (or
    containing the first config file specified using `-f`)
    - The `basename` of the current directory if no config file is specified
    Project names must contain only lowercase letters, decimal digits, dashes,
    and underscores, and must begin with a lowercase letter or decimal digit. If
    the `basename` of the project directory or current directory violates this
    constraint, you must use one of the other mechanisms.

    ```console
    $ docker compose -p my_project ps -a
    NAME                 SERVICE    STATUS     PORTS
    my_project_demo_1    demo       running

    $ docker compose -p my_project logs
    demo_1  | PING localhost (127.0.0.1): 56 data bytes
    demo_1  | 64 bytes from 127.0.0.1: seq=0 ttl=64 time=0.095 ms
    ```

    ### Use profiles to enable optional services

    Use `--profile` to specify one or more active profiles
    Calling `docker compose --profile frontend up` starts the services with the profile `frontend` and services
    without any specified profiles.
    You can also enable multiple profiles, e.g. with `docker compose --profile frontend --profile debug up` the profiles `frontend` and `debug` is enabled.

    Profiles can also be set by `COMPOSE_PROFILES` environment variable.

    ### Configuring parallelism

    Use `--parallel` to specify the maximum level of parallelism for concurrent engine calls.
    Calling `docker compose --parallel 1 pull` pulls the pullable images defined in the Compose file
    one at a time. This can also be used to control build concurrency.

    Parallelism can also be set by the `COMPOSE_PARALLEL_LIMIT` environment variable.

    ### Set up environment variables

    You can set environment variables for various docker compose options, including the `-f`, `-p` and `--profiles` flags.

    Setting the `COMPOSE_FILE` environment variable is equivalent to passing the `-f` flag,
    `COMPOSE_PROJECT_NAME` environment variable does the same as the `-p` flag,
    `COMPOSE_PROFILES` environment variable is equivalent to the `--profiles` flag
    and `COMPOSE_PARALLEL_LIMIT` does the same as the `--parallel` flag.

    If flags are explicitly set on the command line, the associated environment variable is ignored.

    Setting the `COMPOSE_IGNORE_ORPHANS` environment variable to `true` stops docker compose from detecting orphaned
    containers for the project.

    ### Use Dry Run mode to test your command

    Use `--dry-run` flag to test a command without changing your application stack state.
    Dry Run mode shows you all the steps Compose applies when executing a command, for example:
    ```console
    $ docker compose --dry-run up --build -d

    ```
    From the example above, you can see that the first step is to pull the image defined by `db` service, then build the `backend` service.
    Next, the containers are created. The `db` service is started, and the `backend` and `proxy` wait until the `db` service is healthy before starting.

    Dry Run mode works with almost all commands. You cannot use Dry Run mode with a command that doesn't change the state of a Compose stack such as `ps`, `ls`, `logs` for example.
