**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.
|
|
|
|
|
|
```bash
|
|
$ 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
|
|
3l1f6uzcuoa3 * swarm-master READY ACTIVE REACHABLE Yes
|
|
```
|
|
|
|
### --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](node_accept.md) 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
|
|
|
|
|
|
```bash
|
|
$ 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
