# Ansible Role: chrony_exporter
## Description
Deploy prometheus [chrony_exporter](https://github.com/superq/chrony_exporter) 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](defaults/main.yml) file as well as in [meta/argument_specs.yml](meta/argument_specs.yml).
Please refer to the [collection docs](https://prometheus-community.github.io/ansible/branch/main/chrony_exporter_role.html) for description and default values of the variables.
## Example
### Playbook
Use it in a playbook as follows:
```yaml
- hosts: all
roles:
- prometheus.prometheus.chrony_exporter
```
### TLS config
Before running chrony_exporter role, the user needs to provision their own certificate and key.
```yaml
- hosts: all
pre_tasks:
- name: Create chrony_exporter cert dir
file:
path: "/etc/chrony_exporter"
state: directory
owner: root
group: root
- name: Create cert and key
openssl_certificate:
path: /etc/chrony_exporter/tls.cert
csr_path: /etc/chrony_exporter/tls.csr
privatekey_path: /etc/chrony_exporter/tls.key
provider: selfsigned
roles:
- prometheus.prometheus.chrony_exporter
vars:
chrony_exporter_tls_server_config:
cert_file: /etc/chrony_exporter/tls.cert
key_file: /etc/chrony_exporter/tls.key
chrony_exporter_basic_auth_users:
randomuser: examplepassword
```
### 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](https://github.com/superq/demo-site) and the site is hosted on [DigitalOcean](https://digitalocean.com).
## Local Testing
The preferred way of locally testing the role is to use Docker and [molecule](https://github.com/ansible-community/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.

# Troubleshooting
## Bad requests (HTTP 400)
This role downloads checksums from the Github project to verify the integrity of artifacts installed on your servers. When downloading the checksums, a "bad request" error might occur.
This happens in environments which (knowningly or unknowling) use the [netrc mechanism](https://www.gnu.org/software/inetutils/manual/html_node/The-_002enetrc-file.html) to auto-login into servers.
Unless netrc is needed by your playbook and ansible roles, please unset the var like so:
```
$ NETRC= ansible-playbook ...
```
Or:
```
$ export NETRC=
$ ansible-playbook ...
```
