A fuzzy wrapper for the docker cli. Execute a docker command for all containers who match a search term. Do something sensible if no command or no search terms are provided.

docker-grep.sh

docker_ps_formatted(){ docker ps -a --format "table {{.Names}}\t{{.Image}}\t{{.Status}}\t{{.Ports}}" }
# dockerg [ARGS] SEARCH
# basically docker ps | grep SEARCH | xargs docker ARGS
# but all args are optional
# e.g. 'dockgerg bank' -> check which services are found; dockgerg logs --tail 15 bank -> log the service
# e.g. 'dockerg start Exited' -> start all containers with status 'Exited'
dockgerg(){
    if [ "$#" -eq 0 ]; then docker_ps_formatted; return; fi
    SEARCH=${@:$#};
    if [ "$#" -eq 1 ]; then docker_ps_formatted | grep $SEARCH; return; fi
    ARGS=${@:1:$# - 1};
    docker_ps_formatted | grep $SEARCH | awk "{print \$1}" | xargs docker $(echo $ARGS);
