title: create — Create a discovery token

|
||
|
||
The `create` command uses Docker Hub's hosted discovery backend to create a unique *discovery token* for your cluster. For example:
|
||
|
||
$ docker run --rm swarm create
|
||
86222732d62b6868d441d430aee4f055
|
||
|
||
Later, when you use [`manage`](manage.md) or [`join`](join.md) to create Swarm managers and nodes, you use the discovery token in the `<discovery>` argument. For instance, `token://86222732d62b6868d441d430aee4f055`. The discovery backend registers each new Swarm manager and node that uses the token as a member of your cluster.
|
||
|
||
Some documentation also refers to the discovery token as a *cluster_id*.
|
||
|
||
> **Warning**: Docker Hub's hosted discovery backend is not recommended for production use. It’s intended only for testing/development.
|
||
|
||
For more information and examples about this and other discovery backends, see the [Docker Swarm Discovery](../discovery.md) topic.
