Use a task to enable or disable the Puppet daemon for a group of agents in Puppet 5.0 and 6.0📍

You’ve identified a group of nodes where you’d like to enable or disable the Puppet daemon.

Version and installation information

Puppet version: 5.0 and 6.0

Solution

Before you begin: Install the puppetlabs-support_tasks module. To use the tasks in the support_tasks module with Puppet, install Bolt on a workstation.

Learn more about:

• Installing modules using a Puppetfile
• Running tasks with Bolt
• The support_tasks module

Follow these steps to run tasks to enable and disable the daemon:

To enable agents:

By default, this will enable all agents. However, you can apply it to a set of nodes by editing the list of nodes created in the first step.

1. Create a list of disabled nodes in nodefile.txt by using the steps in Identifying nodes where the Puppet daemon is enabled or disabled.

2. Enable the agents in the list by running a task with the list of nodes as input. The required parameter puppet_mode is set to enable. On the primary server, run:

   bolt task run support_tasks::st0286_change_puppet_daemon_runmode puppet_mode=enable --nodes @nodefile.txt

To disable agents:

Disable an agent by running task st0285 that sets the parameter puppet_mode to disable.

For example to disable an agent that you’re doing testing on, on the primary server, run:

bolt task run support_tasks::st0286_change_puppet_daemon_runmode puppet_mode=disable reason='down for testing'--targets agent1.example.com

Note: The reason parameter is optional.
