Vinculum is a command and control system for low powered devices that cannot run k3s or docker swarm. It uses a single binary in a leader/follower mode with a grpc protocol to send commands. There is a small amount of intelligence in scheduling and should be thought of as a shortcut from ansible/ssh commands.
As an example this works well across a cluster of Raspberry Pi Zero compute units.
curl https://raw.githubusercontent.com/AlexsJones/vinculum/master/install.sh | sh -
Start the leader
vinculum leader listen
Start a follower
vinculum follower connect -s localhost:7559
Run a command
vinculum ctl shell --command="ls /var/log"
