Thank you to all the contributors (@egdavid, @stefan-matic, @iolpltuisciaoln, @iMilnb) with your useful fix and additions to these aliases, I've finally revised the gist with all your contributions

For the record, the dc alias may conflict with the GNU/Linux arbitrary precision calculator dc.

Running dip consecutively duplicates the entries, so I had to unset the OUT variable at the end.
List all IPs of a container using docker inspect --format flag.
Also, I had to use echo -e $OUT to make the tabs and newlines work correctly.

function dip-fn {
    echo "IP addresses of all named running containers"

    for DOC in `dnames-fn`
    do
        IP=`docker inspect --format='{{range .NetworkSettings.Networks}}{{.IPAddress}} {{end}}' "$DOC"`
        OUT+=$DOC'\t'$IP'\n'
    done
    echo -e $OUT | column -t
    unset OUT
}

This article has a few handy ones. https://medium.com/hackernoon/handy-docker-aliases-4bd85089a3b8
Would you like me to add some of these to your file?

@crsibler yes sure feel free to add some of these aliases! thank you

@jgrodziski here is my revision. https://gist.github.com/crsiebler/dff474dcf8f57f2ce59c2b2815892530/revisions This is my first time working with Gists. Is there no pull request type feature for them?

@crsiebler Correct, gists have no PR. Consider gists as code snippets or notes that can be e.g. discussed.

Could those who use Docker extensively weigh in on rough weight of scripted/interactive use thus the utility of placing these aliases in .bashrc for consistency in syntax muscle memory? Does it make more sense to script docker commands long hand for portability across systems without automated config/versioning across a dozen or so systems?

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. ?
