Ansible playbook for BAR monitoring

Warning

This repo is work in progress, not finished, nothing to see here yet.

This is an Ansible playbook for setting up central BAR monitoring server.

Usage

TODO

Local testing

Setup

We use Incus for local testing. Make sure you have it installed and initialized following the official getting started docs.

To create a new container and initialize it via cloud-init, run the following command:

touch .incus-integration-on && \
chmod 0600 test.ssh.key && \
incus launch images:debian/trixie/cloud bar-mon-test < test.incus.yml && \
incus exec bar-mon-test -- cloud-init status --wait

Then test that it works for ansible:

ansible dev -m shell -a 'uname -a'

The test container runs a few different services, and depends on a few *.bar-mon.local domain names pointing at the incus container so they are independently routable from web browser. Easiest is to add a new entry in /etc/hosts like:

{incus_container_ip} id.bar-mon.local grafana.bar-mon.local metrics.bar-mon.local

you can add/update it with:

ansible ,localhost -b -K -m lineinfile -a "path=/etc/hosts regexp='.*bar-mon.*' line='$(ansible-inventory --host test | jq -r '.ansible_host') id.bar-mon.local grafana.bar-mon.local metrics.bar-mon.local'"

Usage

Now you can use all the playbooks and roles as usual, just make sure you are targeting the dev inventory group or test host. For example:

ansible-playbook -l dev play.yml

You can ssh into it with something like:

ssh -i test.ssh.key ansible@$(ansible-inventory --host test | jq -r '.ansible_host')

Or enter directly into root container shell with:

incus exec bar-mon-test -- /bin/bash

Cleanup

To stop and remove the container:

incus stop bar-mon-test && incus delete bar-mon-test
