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.
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.
I often just do
docker ps | awk "{print $1}" | xargs docker stopAdd some filtering in there and you’re golden
How tf do you remember that lol, I’m always amazed by CLI focused people being able to remember so much!
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.
Just a few shortcuts that may help:
docker psis an alias fordocker 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.
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
Is there a way to do this without cd-ing to the directory with the compose file first?
You can use -f /path/to/compose.yaml to call it from wherever you like.
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.
My better way is just using Portainer, select some containers and hit the stop button.
If I eventually get around to using a GUI, I’ll check out portainer
