Deploy prometheus node exporter using ansible.
- Ansible >= 2.4
All variables which can be overridden are stored in defaults/main.yml file as well as in table below.
Name | Default Value | Description |
---|---|---|
node_exporter_version |
0.16.0 | Node exporter package version |
node_exporter_web_listen_address |

node_exporter_disabled_collectors |

Use it in a playbook as follows:
- hosts: all
roles:
- cloudalchemy.node-exporter
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.
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. We are using tox to simplify process of testing on multiple ansible versions. To install tox execute:
pip install tox
To run tests on all ansible versions (WARNING: this can take some time)
tox
To run a custom molecule command on custom environment with only default test scenario:
tox -e py27-ansible25 -- molecule test -s default
For more information about molecule go to their docs.
If you would like to run tests on remote docker host just specify DOCKER_HOST
variable before running tox tests.
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 which will take more time than local testing, so please be patient.
