description: Create a Swarm manager.
keywords: swarm, create
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. Its intended only for testing/development.
For more information and examples about this and other discovery backends, see the [Docker Swarm Discovery](../discovery.md) topic.
