Add following
- cadvisor_env_metadata_whitelist
- cadvisor_whitelisted_container_labels
- cadvisor_store_container_labels
Tested with this simple playbook:
---
- name: Install cAdvisor
hosts: localhost
become: yes
tasks:
- name: Import cAdvisor role
import_role:
name: cadvisor
vars:
cadvisor_docker_only: true
cadvisor_enable_metrics: [ "cpu", "memory", "network", "oom_event" ]
cadvisor_whitelisted_container_labels: [ "com.docker.compose.oneoff" ]
cadvisor_env_metadata_whitelist: [ "JEKYLL_ENV", "PATH" ]
cadvisor_store_container_labels: false
Also tested dropping the options, which is why I decided to explicitly set
store_container_labels: true (which is the cadvisor default).

Ansible Role: cadvisor
Description
Deploy cadvisor using ansible.
Requirements
- Ansible >= 2.9 (It might work on previous versions, but we cannot guarantee it)
- gnu-tar on Mac deployer host (
brew install gnu-tar) - Passlib is required when using the basic authentication feature (
pip install passlib[bcrypt])
Role Variables
All variables which can be overridden are stored in defaults/main.yml file as well as in meta/argument_specs.yml. Please refer to the collection docs for description and default values of the variables.
Example
Playbook
Use it in a playbook as follows:
- hosts: all
roles:
- prometheus.prometheus.cadvisor
Demo site
We provide an example site that demonstrates a full monitoring solution based on prometheus and grafana. The repository with code and links to running instances is available on github and the site is hosted on DigitalOcean.
Local Testing
The preferred way of locally testing the role is to use Docker and molecule (v3.x). You will have to install Docker on your system. See "Get started" for a Docker package suitable for your system. Running your tests is as simple as executing molecule test.
Continuous Integration
Combining molecule and circle 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 quite a large test matrix which can take more time than local testing, so please be patient.
