Ansible Role: fluentd

Description

Install and manage fluentd log forwarder and agregator.

Requirements

• Ansible >= 2.7 (It might work on previous versions, but we cannot guarantee it)

Role Variables

All variables which can be overridden are stored in defaults/main.yml file as well as in table below.

Name	Default Value	Description
fluentd_custom_conf	[]	Paths to custom configuration templates. Configuration examples.
fluentd_metrics	False	Enable or disable fluentd metrics exporter. Metrics exported in prometheus format
fluentd_plugins	[]	List of additional plugins

Example

Playbook

Use it in a playbook as follows:

- hosts: all
  become: true
  roles:
    - cloudalchemy.fluentd

Demo site

We provide demo site for full monitoring solution based on prometheus and grafana. Repository with code and links to running instances is available on github and site is hosted on DigitalOcean.

Local Testing

The preferred way of locally testing the role is to use Docker and molecule (v2.x). You will have to install Docker on your system. See Get started for a Docker package suitable to for your system. All packages you need to can be specified in one line:

pip install ansible 'ansible-lint>=3.4.15' 'molecule>2.13.0' docker 'testinfra>=1.7.0' jmespath

This should be similar to one listed in .travis.yml file in install section. After installing test suit you can run test by running

molecule test --all

For more information about molecule go to their docs.

Travis CI

Combining molecule and travis CI allows us to test how new PRs will behave when used with multiple ansible versions and multiple operating systems. This also allows use to create test scenarios for different role configurations. As a result we have a quite large test matrix (42 parallel role executions in case of ansible-prometheus) which will take more time than local testing, so please be patient.
