| description: | Create your default Deis cluster. |
Applications on Deis are deployed to a :ref:`cluster`. Before you can deploy applications, you need to create a cluster.
The parameters to deis clusters:create are:
- cluster name - the name used by Deis to reference the cluster
- cluster hostname - the hostname for the cluster -- applications are accessible under this domain
- cluster members (--hosts) - a comma-separated list of IP addresses of cluster members -- not necessarily all members, but at least one
- auth SSH key (--auth) - the SSH private key used to provision servers (for EC2 and Rackspace, this key is likely ~/.ssh/deis)
For example, to create a cluster on a local Deis installation:
$ deis clusters:create dev local.deisapp.com --hosts=local.deisapp.com --auth=~/.vagrant.d/insecure_private_key
