Add this module to your Puppetfile:
mod 'attachmentgenie-loki', '2.0.0'Learn more about managing modules with a PuppetfileDocumentation
attachmentgenie-loki
Deploy and configure loki on a node.
Description
It primarily:
- Discovers targets
- Attaches labels to log streams
- Pushes them to the Loki instance.
Currently, Loki can tail logs from two sources: local log files and the systemd journal (on AMD64 machines only).
Usage
All options and configuration can be done through interacting with the parameters on the main loki class. These are now documented via Puppet Strings
You can view example usage in REFERENCE.
## Reference
See [REFERENCE](REFERENCE.md).
## Limitations
This is where you list OS compatibility, version compatibility, etc.
## Development
### Running tests
This project contains tests for both rspec-puppet and litmus to verify functionality. For detailed information on using these tools, please see their respective documentation.
#### Testing quickstart:
pdk bundle install pdk bundle exec rake 'litmus:provision_list[puppet6]' pdk bundle exec rake 'litmus:install_agent[puppet6]' pdk bundle exec rake litmus:install_module pdk bundle exec rake litmus:acceptance:parallel pdk bundle exec rake litmus:tear_down
