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’

    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
