jgrodziski/docker-aliases.sh

this is vital, especially when coupled with fzf:

personally, I do automatic configuration of the environment on every host like this:
sh -c "$(curl -fsSL https://raw.githubusercontent.com/iolpltuisciaoln/envup/master/envup.sh)" "" --unattended

@jgrodziski, I have added functions to allow a few of the aliases to use partial ID or partial name, making things even easier.
I was going to create a merge request or pull request but wasn't clear on how to.
My fork is at https://gist.github.com/mspronk/cab0c175b876ef662e25b1ba2d22b069, feel free to use or merge it in.

PS credits for the inspiration of the additional function go to https://gist.github.com/akarzim

How can I use this aliases with zsh?

Hi, thank you for your contribution!
I would like to donate something I find useful, many times I use grep to filter images so I included this in my alias:

alias dim1="i=!:1 && docker images | grep $i "`

Example:
dim jenkins
is equal to `docker images | grep jenkins"

Does anyone know why if I run the alias drmid=drmid-fn in zsh to clean <none> images, I am getting:

Error: No such image: sha256:a55935bf5f1c144801678f4d723f8c3ffd041108284f69c76801d33562a11f98

But, if I copy/paste the command directly into the terminal it works?:

I have found a solution. It seems in bash/zsh if we use $(docker images -q -f dangling=true), the output is a string with break line "\n" and this causes the docker rmi not to read the full list of none images, e.g.

sha256:a55935bf5f1c144801678f4d723f8c3ffd041108284f69c76801d33562a11f98
sha256:a55935bf5f1c144801678f4d723f8c3ffd041108284f69c76801d33562a11f98
sha256:a55935bf5f1c144801678f4d723f8c3ffd041108284f69c76801d33562a11f98
sha256:a55935bf5f1c144801678f4d723f8c3ffd041108284f69c76801d33562a11f98
sha256:a55935bf5f1c144801678f4d723f8c3ffd041108284f69c76801d33562a11f98

But, if we use a function to run docker images -q -f dangling=true instead, then the alias works as expected since the output list in concatenated by \t

function noneimages {
       docker images --filter "dangling=true" -q --no-trunc
}

function docker-remove-none-images {
       [ ! -z "$(noneimages)" ] && docker rmi $(noneimages) || echo "no dangling images."
}

alias cdi=docker-remove-none-images

Then, the output is:

sha256:a55935bf5f1c144801678f4d723f8c3ffd041108284f69c76801d33562a11f98sha256:a55935bf5f1c144801678f4d723f8c3ffd041108284f69c76801d33562a11f98sha256:a55935bf5f1c144801678f4d723f8c3ffd041108284f69c76801d33562a11f98sha256:a55935bf5f1c144801678f4d723f8c3ffd041108284f69c76801d33562a11f98sha256:a55935bf5f1c144801678f4d723f8c3ffd041108284f69c76801d33562a11f98

And the none images are deleted.

Thanks all for submitting your aliases - useful stuff.

I am fond of Git's approach to aliases so I am using something like the below to achieve something similar for arbitrary CLI tools. Maybe someone will find it useful.

# I simply use alias d=__docker-wrapper which removes the need
# for `command docker` in the fn body, but for clarity, it's
# `docker` here.
alias docker=__docker-wrapper

__docker-wrapper() {
	if [[ "$1" == "rmid" ]]
	then
		command docker rmi $(command docker images --quiet --all --filter 'dangling=true')
	elif [[ "$1" == "cm" ]]
	then
		shift 1
		command docker compose "$@"
	else
		command docker "$@"
	fi
}

I see that this gist still uses docker-compose cmd line instead of docker compose, which I believe the lather is what is used now for docker. Should this gist be updated to reflect that?

@j-antunes thanks, yes I updated the gist with docker compose instead of docker-compose

Hello, I edited and try your snippet, it is cool I add shortcut I love to use

#     dbash <container>: run a bash shell into a given container           #
#     dsh <container>: run a sh shell into a given container               #


function dbash-fn {
    docker exec -it $(docker ps -aqf "name=$1") bash;
}

function dsh-fn {
    docker exec -it $(docker ps -aqf "name=$1") sh;
}

alias dbash=dbash-fn
alias dsh=dsh-fn 

Nice, thanks !

Some were the exact aliases I've been using for years on my own.

With two extras :

alias dcl='docker compose logs -f'

to display logs for a particular compose file.

and

function dupdate() {
	docker compose pull && docker compose build --no-cache
}

to update docker compose containers.

I don't get the use of aliases pointing to functions instead of giving the function the direct alias name ?
like so :

function drmid {
       imgs=$(docker images -q -f dangling=true)
       [ ! -z "$imgs" ] && docker rmi "$imgs" || echo "no dangling images."
}

and also why this kind of complicate things :

function dc-fn {
        docker compose $*
}
alias dc=dc-fn

instead of simply :

alias dc='docker compose'

There might be some reasons I don't get since I only use bash e.g. ?

Unless I'm missing something, dnames can be shortened to:

alias dnames="docker ps --format '{{.Names}}'"

or

funciton dnames() {
        docker ps --format '{{.Names}}'
}

Speed also seems to be better:

 ~ ❯ hyperfine "docker ps --format '{{.Names}}'" ./test-dnames
Benchmark 1: docker ps --format '{{.Names}}'
  Time (mean ± σ):      40.0 ms ±  11.0 ms    [User: 9.4 ms, System: 10.8 ms]
  Range (min … max):    21.5 ms …  64.7 ms    46 runs

Benchmark 2: ./test-dnames
  Time (mean ± σ):     136.8 ms ±  24.9 ms    [User: 49.8 ms, System: 61.2 ms]
  Range (min … max):    96.0 ms … 193.9 ms    24 runs

Summary
  docker ps --format '{{.Names}}' ran
    3.42 ± 1.13 times faster than ./test-dnames
