Bash script helper to remove Docker images and containers.

dkcleanup.sh

#!/bin/bash

# options:
# remove stopped containers and untagged images
#   $ dkcleanup 
# remove all stopped|running containers and untagged images
#   $ dkcleanup --reset
# remove containers|images|tags matching {repository|image|repository\image|tag|image:tag}
# pattern and untagged images
#   $ dkcleanup --purge {image}
# everything
#   $ dkcleanup --nuclear

if [ "$1" == "--reset" ]; then
    # Remove all containers regardless of state
    docker rm -vf $(docker ps -a -q) 2>/dev/null || echo "No more containers to remove."
elif [ "$1" == "--purge" ]; then
    # Attempt to remove running containers that are using the images we're trying to purge first.
    (docker rm -vf $(docker ps -a | grep "$2/\|/$2 \| $2 \|:$2\|$2-\|$2:\|$2_" | awk '{print $1}') 2>/dev/null || echo "No containers using the \"$2\" image, continuing purge.") &&\
    # Remove all images matching arg given after "--purge"
    docker rmi $(docker images | grep "$2/\|/$2 \| $2 \|$2 \|$2-\|$2_" | awk '{print $3}') 2>/dev/null || echo "No images matching \"$2\" to purge."
else
    # This alternate only removes "stopped" containers
    docker rm -vf $(docker ps -a | grep "Exited" | awk '{print $1}') 2>/dev/null || echo "No stopped containers to remove."
fi

if [ "$1" == "--nuclear" ]; then
    docker rm -vf $(docker ps -a -q) 2>/dev/null || echo "No more containers to remove."
    docker rmi $(docker images -q) 2>/dev/null || echo "No more images to remove."
else
    # Always remove untagged images
    docker rmi $(docker images | grep "<none>" | awk '{print $3}') 2>/dev/null || echo "No untagged images to delete."
fi

exit 0

You can try out below script, i am using that below

#!/bin/bash

timestamp=$(date +%Y%m%d_%H%M%S)
log_path="`pwd`"
filename=docker_cleanup_$timestamp.log
log=$log_path/$filename


docker_space_before(){
CURRENTSPACE=`docker system df`
echo "Current Docker Space:" >> $log
echo $CURRENTSPACE >>$log
}
docker_find (){
echo "#####################################################################" >> $log
echo "Finding images" >> $log
echo "#####################################################################" >> $log
REMOVEIMAGES=`docker images | grep " [days|months|weeks]* ago" | awk '{print $3}'`

echo "Listing images that needs to be cleaned up" >> $log
echo $REMOVEIMAGES >>$log

}

docker_cleanup(){
echo "#####################################################################" >> $log
echo "Cleaning images" >> $log
echo "#####################################################################" >> $log
docker rmi ${REMOVEIMAGES}
}

docker_space_after(){
CURRENTSPACE=`docker system df`
echo "Current Docker Space, after clean up:" >> $log
echo $CURRENTSPACE >>$log
}
docker_space_before
docker_find
docker_cleanup
docker_space_after

Thanks for this.
