How to show all running containers created by docker-compose, globally, regardless of docker-compose.yml

I have several docker-compose.yml files, running ok with docker-compose up, individually.

Each docker-compose runs several containers.

After they are up, I can’t see what containers are up with docker ps.
I can see something with docker-compose ps, but only for a specific docker-compose.yml.

I want access to global polling of the containers state.

How can I list all running containers, no matter their origin?

    Here is kind of a guess based on the clues of your question.

    When you do run containers via docker-compose up, please do mind that hitting CTRL+C will actually stop your containers.

    Here is an example of doing this:

    $ docker-compose up
[+] Running 1/0
 ⠿ Container docker-test-1  Created                                  0.0s
Attaching to docker-test-1
^CGracefully stopping... (press Ctrl+C again to force)
[+] Running 1/1
 ⠿ Container docker-test-1  Stopped                                 10.2s
canceled

    The important part here being: ^CGracefully stopping...

    If you want to keep them running, you will have to run docker-compose up in a detached mode, with the help of the -d option.

    -d, --detach       Detached mode: Run containers in the background,
                   print new container names. Incompatible with
                   --abort-on-container-exit.

    Source: https://docs.docker.com/compose/reference/up/

    So doing,

    docker-compose up -d && docker ps

    Should actually give you what you expected.
    E.g.:

    $ docker-compose up -d && docker ps
[+] Running 2/2
 ⠿ Network docker_default   Created                                                                                   0.1s
 ⠿ Container docker-test-1  Started                                                                                   0.5s
CONTAINER ID   IMAGE     COMMAND               CREATED        STATUS                  PORTS     NAMES
ab9f422247c9   alpine    "tail -f /dev/null"   1 second ago   Up Less than a second             docker-test-1

    And if you want to see all container, regardless of their state, you can use the -a option of docker ps.

    --all , -a        Show all containers (default shows just running)

    Source: https://docs.docker.com/engine/reference/commandline/ps/

    E.g.:

    $ docker-compose up  
[+] Running 2/2
 ⠿ Network docker_default   Created                                                                                   0.1s
 ⠿ Container docker-test-1  Created                                                                                   0.1s

canceled
$ docker ps -a

    Docker compose adds labels to each container that it creates. If you want to get all containers created by compose, you can perform a container ls and apply a filter.

    docker container ls --filter label=com.docker.compose.project

    This will show all running container created by compose, regardless of the project name.

    For example, I created some containers from different compose projects. With the filter, I get only those, but no other container that have not been created by compose and therefore don’t have a project label.

    $ base='{{.Status}}t{{.ID}}t{{.Names}}t{{.Image}}t{{.Ports}}t{{.Networks}}t{{.Mounts}}'
$ compose='{{.Label "com.docker.compose.project"}}t{{.Label "com.docker.compose.service"}}'

$ docker container ls --all 
  --filter label=com.docker.compose.project 
  --format "table $composet$base"

    If you want to see all container regardless of their state, you can add the --all or short -a flag to the ls command, like I did in my example. Otherwise, only running containers are shown.
