# Create a Swarm
After you complete the [tutorial setup](index.md) steps, you're ready
to create a Swarm. Make sure the Docker Engine daemon is started on the host
machines.
1. Open a terminal and ssh into the machine where you want to run your manager
node. For example, the tutorial uses a machine named `manager1`.
2. Run `docker swarm init --listen-addr MANAGER-IP:PORT` to create a new Swarm.
In the tutorial, the following command creates a Swarm on the `manager1` machine:
```
$ docker swarm init --listen-addr 192.168.99.100:2377
Swarm initialized: current node (09fm6su6c24qn) is now a manager.
```
The `--listen-addr` flag configures the manager node to listen on port
`2377`. The other nodes in the Swarm must be able to access the manager at
the IP address.
3. Run `docker info` to view the current state of the Swarm:
```
$ docker info
Containers: 2
Running: 0
Paused: 0
Stopped: 2
...snip...
Swarm:
NodeID: 09fm6su6c24qn
IsManager: YES
Managers: 1
Nodes: 1
...snip...
```
4. Run the `docker node ls` command to view information about nodes:
```
$ docker node ls
ID NAME MEMBERSHIP STATUS AVAILABILITY MANAGER STATUS LEADER
09fm6su6c24q * manager1 Accepted Ready Active Reachable Yes
```
The `*` next to the node id, indicates that you're currently connected on
this node.
Docker Swarm automatically names the node for the machine host name. The
tutorial covers other columns in later steps.
## What's next?
In the next section of the tutorial, we'll [add two more nodes](add-nodes.md) to
the cluster.
