# Docker Functions
# A small collection of commands that can be quite useful when 
# working with Docker.

# Stop all containers on the system.

    docker stop $(docker ps -aq)
}

# Stop all containers on the system and remove them.
remove_all_containers() {
    docker stop $(docker ps -aq)
    docker rm $(docker ps -aq)
}

# Find, kill and completely remove any and all Docker containers,
# images, volumes and networks that might be hiding on your system. 
docker_armageddon() {
    remove_all_containers
    docker network prune -f
    docker rmi -f $(docker images --filter dangling=true -qa)
    docker volume rm $(docker volume ls --filter dangling=true -q)
    docker rmi -f $(docker images -qa)
