images, I am getting:

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

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. ?
Does anyone know why if I run the alias
drmid=drmid-fn
