Description
In order to better streamline and standardize the Gremlin agent installation and configuration, this module provides a supported method to manage and maintain the gremlin agent on your systems.
Setup
What gremlin_agent affects
The configuration follows the steps documented on the Gremlin docs
- It installs the dependencies required based on the host OS.
- It installs the gremlin repository, the agent, and the daemon.
- It configures the daemon via
config.yaml, and manages the service.
Beginning with gremlin_agent
You need to provide the gremlin_team_id and either gremlin_team_secret or the gremlin_team_certificate_or_file and gremlin_team_private_key_or_file
These can either come from Hiera or called directly as the below example:
class { 'gremlin_agent':
gremlin_team_id => '11111111-1111-1111-1111-111111111111',
gremlin_team_secret => '11111111-1111-1111-1111-111111111111'
}
gremlin_agent::gremlin_team_id: '11111111-1111-1111-1111-111111111111'
gremlin_agent::gremlin_team_secret: '11111111-1111-1111-1111-111111111111'
Usage
If you wish to use the certificate pair instead of the team secret, you can provide either the filepath (prefixed with file://) or the whole certificate.
class { 'gremlin_agent':
gremlin_team_id => '11111111-1111-1111-1111-111111111111',
gremlin_team_certificate_or_file => 'file://var/lib/gremlin/key.cert',
gremlin_team_private_key_or_file => 'file://var/lib/gremlin/key.pem',
}
Additional parameters that can be set can be viewed in the REFERENCE.md

Limitations
This module has had limited testing and doesn't currently support all features. Please open an issue for any bugs discovered.
Development
Feel free to open a PR for suggested changes or improvements.
TODO:
- Finish fleshing out Windows support.
- Add tasks to trigger gremlin checks.
- Add some additional config validation to confirm agent is successfully talking to control plane.

What are tasks?
Modules can contain tasks that take action outside of a desired state managed by Puppet. It’s perfect for troubleshooting or deploying one-off changes, distributing scripts to run across your infrastructure, or automating changes that need to happen in a particular order as part of an application deployment.
