How to take actions on multiple docker containers at once
How to take actions on multiple docker containers at once
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'
You're viewing a single thread.
If the containers are related you could use docker-compose, which has commands to stop / restart/ remove all containers at once.
I use Compose even when I have a single container to run because I can put all the config bits I need into a file and can then do most of the work without remembering lots of command line options and often without even needing to mention the service name directly.
Same. I can't remember the last time I started a docker container without a compose file.
I keep a docker directory in my home dir that has a directory for each docker container/stack in a compose file. Taking down a container looks like so.
- cd docker/wallabag
- docker-compose down
Imo, the best way to work with docker.
i do the exact same
Cool, didn't know that!
Just tested, so you have to cd to the directory with the docker-compose.yml file in it first
you can also use the -f option to specify the compose file without going to it.
