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

-n, --cluster TEXT Cluster name [required]
--flush-iptables Flush IPTables [default: False]
--selinux-permissive Set SELinux to permissive [default:

--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
flush-iptables Flush IPTables
plugins Provision enabled plugins
roles Set roles on the cluster nodes
salt Provision Salt
security-settings Execute the security settings
selinux-context Set SELinux contexts
selinux-permissive Set SELinux to permissive
