# Provisioning a cluster

To provision or reprovision an existing cluster, run:

    $ adam provision -n [cluster-name]

EXAMPLE: To provision the cluster named “cluster”:

    $ adam provision -n cluster

## Customizing the provision command–advanced

By default, the `adam provision` command:

- Checks SSH connectivity.
- Creates a default user.
- Installs Salt.
- Syncs formulas.
- Provisions enabled plugins and security settings that are defined in the cluster’s profile.

To run only a portion of this provisioning process, use `adam provision` options and subcommands to control what happens during provisioning.

Run `adam provision --help` to see the available options and subcommands:

    $ adam provision --help
    Usage: adam provision [OPTIONS] COMMAND [ARGS]...

      Execute all the provisioning steps for a cluster

      See subcommands help for more info. Usage: adam provision -n

    Options:
      -n, --cluster TEXT    Cluster name  [required]
      --flush-iptables      Flush IPTables  [default: False]
      --selinux-permissive  Set SELinux to permissive  [default:
                              False]
      --selinux-context     Set SELinux contexts  [default: False]
      --plugins             Install enabled plugins on provision
                              [default: False]
      -h, --help            Show this message and exit.

    Commands:
      anaconda-user       Create the default anaconda user in all
                            the nodes
      check-ssh           Check SSH connection to the nodes
