dsexec is a cli helper to help you do a docker socket exec in a docker service. dsexec will lookup running docker swarm service tasks of the requested service, configure a DOCKER_HOST (checking known host & co) context to the remote docker-socket, and spawn you a docker exec of the requested shell.
# in a docker swarm context
npm install -g dsexec
dsexec [service_name] [shell=/bin/bash]
# make sure you have a docker-socket service available and deployed to all nodes.
