From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

How to take actions on multiple docker containers at once (lemmy.nz)

submitted 1 year ago by [email protected] to c/[email protected]

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
