Warning: this command is part of the Swarm management feature introduced in Docker 1.12, and might be subject to non backward-compatible changes.
swarm init
Usage: docker swarm init [OPTIONS]
Initialize a Swarm.
Options:
--auto-accept value Acceptance policy (default [worker,manager])
--force-new-cluster Force create a new cluster from current state.
--help Print usage
--listen-addr value Listen address (default 0.0.0.0:2377)
--secret string Set secret value needed to accept nodes into cluster
Initialize a Swarm cluster. The docker engine targeted by this command becomes a manager in the newly created one node Swarm cluster.
$ docker swarm init --listen-addr 192.168.99.121:2377
Initializing a new swarm
$ docker node ls
ID NAME STATUS AVAILABILITY/MEMBERSHIP MANAGER STATUS LEADER

--auto-accept value
This flag controls node acceptance into the cluster. By default, both worker and manager
nodes are auto accepted by the cluster. This can be changed by specifing what kinds of nodes
can be auto-accepted into the cluster. If auto-accept is not turned on, then
node accept can be used to explicitly accept a node into the cluster.
For example, the following initializes a cluster with auto-acceptance of workers, but not managers
$ docker swarm init --listen-addr 192.168.99.121:2377 --auto-accept worker
Initializing a new swarm
--force-new-cluster
This flag forces an existing node that was part of a quorum that was lost to restart as a single node Manager without losing its data
--listen-addr value
The node listens for inbound Swarm manager traffic on this IP:PORT
--secret string
Secret value needed to accept nodes into the Swarm
