docker kill $(docker ps -q)

docker rm $(docker ps -a -q)

docker rmi $(docker images -q -f dangling=true)

It might also be useful to create bash aliases for these commands, for example:
~/.bash_aliases

alias dockerkillall='docker kill $(docker ps -q)'
Delete all stopped containers.
alias dockercleanc='printf "\n>>> Deleting stopped containers\n\n" && docker rm $(docker ps -a -q)'
Delete all untagged images.
alias dockercleani='printf "\n>>> Deleting untagged images\n\n" && docker rmi $(docker images -q -f dangling=true)'
Delete all stopped containers and untagged images.
alias dockerclean='dockercleanc || true && dockercleani'
