swarmctl is a replacement command line for docker regarding swarm mode support. This command line is a drop-in replacement, with the exact same UX (actually, running the same code)

• docker swarm => swarmctl swarm
• docker node => swarmctl node
• docker secret => swarmctl secret
• docker config => swarmctl config
• docker service => swarmctl service
• docker stack => swarmctl stack

build: make

then run ./bin/build/swarmctl swarm init
