第3章 Configuring and Setting up Remote Jobs
Use this section as a guide to configuring Satellite to execute jobs on remote hosts.
Any command that you want to apply to a remote host must be defined as a job template. After you have defined a job template you can execute it multiple times.
3.1. About Running Jobs on Hosts
You can run jobs on hosts remotely from Capsules using shell scripts or Ansible tasks and playbooks. This is referred to as remote execution.
For custom Ansible roles that you create, or roles that you download, you must install the package containing the roles on the Capsule base operating system. Before you can use Ansible roles, you must import the roles into Satellite from the Capsule where they are installed.
Communication occurs through Capsule Server, which means that Satellite Server does not require direct access to the target host, and can scale to manage many hosts. Remote execution uses the SSH service that must be enabled and running on the target host. Ensure that the remote execution Capsule has access to port 22 on the target hosts.
Satellite uses ERB syntax job templates. For more information, see Template Writing Reference in the Managing Hosts guide.
Several job templates for shell scripts and Ansible are included by default. For more information, see 「Setting up Job Templates」.
By default, Satellite Server is configured to use the Katello Agent rather than remote execution. To change this setting, navigate to Administer > Settings, click Content, and change the Use remote execution by default setting.
Any Capsule Server base operating system is a client of Satellite Server’s internal Capsule, and therefore this section applies to any type of host connected to Satellite Server, including Capsules.
You can run jobs on multiple hosts at once, and you can use variables in your commands for more granular control over the jobs you run. You can use host facts and parameters to populate the variable values.
In addition, you can specify custom values for templates when you run the command.
For more information, see 「Executing a Remote Job」.
