Again, please tell me if there is a better way to do this.

While testing docker, frequently I need to start/stop/rm containers. I got real sick of having to ls them and copy paste the container ID.

Using this alias, I just have to remember a single part of the name of the container, and I will get the container IDs that can then be included as part of another command:

$ alias dcl='_dcl(){ docker container ls -aq -f name="$1";}; _dcl'

$ dcl snikket
b3fcbc808cc9
1947885fbb24
054d67d2e8b9
d8fe9df5f61f

So now that I’m getting a list of IDs, I can easily, for example, pause all of them:

$ docker container pause $( dcl snikket )
Error response from daemon: container  is not running
Error response from daemon: container  is not running
Error response from daemon: container  is not running
Error response from daemon: container  is not running

The containers weren’t actually running, but this shows the alias working.

dcl obviously stands for ‘docker container ls’

    If the containers are related you could use docker-compose, which has commands to stop / restart/ remove all containers at once.

    I often just do

    docker ps | awk "{print $1}" | xargs docker stop
    

    Add some filtering in there and you’re golden

        I think it has to do with creativity!

        The CLI tools are just small simple tools. The power comes from having the understanding of how each tool works and how they can be combined.

        I don’t remember this string of commands, I know docker, awk and xargs. When I need this, that is the solution I always end up with.

        Dude, I use the CLI all day, every day and I can’t freakin remember half the commands I need.

        If it’s something I use often, I’ll make an alias even if it’s just so I can run ‘alias’ in the terminal to get a list of things I use often.

    This works but I’d just create a function and use that instead of creating an alias that creates a function and then calls itself.

    if your containers are created with a docker compose file you can use docker-compose to target them all

    Just a few shortcuts that may help:

    • docker ps is an alias for docker container ls
    • as long as it can be uniquely identified, a prefix of the container ID can be used instead of copy pasting the entire ID
    • you can use container names instead of IDs
    • tab completion works for container names

    As someone else suggested though, docker compose is probably best suited for this job, but hopefully this helps in other situations.

    I don’t know if this works in docker (usually there is 1:1 equivalency between the two), but with podman you can do something like:

    podman stop --filter name=foo
    

    man podman-stop tells us:

       --filter, -f=filter
           Filter what containers are going to be stopped.  Multiple filters can be given with multiple uses of the --filter flag.  Filters with the same  key  work
           inclusive with the only exception being label which is exclusive. Filters with different keys always work exclusive.

      Usage:  docker stop [OPTIONS] CONTAINER [CONTAINER...]
      
      Options:
        -s, --signal string   Signal to send to the container
        -t, --time int        Seconds to wait before killing the container
      

      Unfortunately no filter here

    You can use the container names to address containers. Whether this is a randomly generated name (docker run… with no --name flag), the compose working dir and service name, or the compose container_name var.

    I also rarely use the container command. docker is sufficient, or docker compose ... while in the working dir of a given compose stack.

    You can of course do it this way too, it’s just extra typing:

    docker container stop $(docker container ls -qf name=snikket)

    I’m using docker packages for Doom Emacs. The main one is docker.el. On top of being faster and easier to use than the cli, you can also do some pretty neat stuff like use dired+tramp to browse files and open them in Emacs.
