Member Prometheus setup for federation

This playbook is to setup a local Prometheus instance that will only scrape the IBP nodes which then can be scraped through Federation.

Requirements

Setup a VM with at at least:

• 1 core
• 256 MB Ram
• 32 GB Storage

Installation

Download the Repo

git clone [email protected]:ibp-network/member-prometheus.git

This Playbook uses the following two collection:

• Prometheus
• Nginx

Install both collections

ansible-galaxy collection install -r requirements.yaml --upgrade --force

Copy the inventory template

cp inventory_template.yaml inventory.yaml

• Set the correct ansible_user for ssh connection
• replace monibp-001 with your correct hostname
• set the correct ansible_host
• set the correct ibp_name name
• set any subodmain you like for alias_prometheus

Nginx

The Nginx collection will install a default nginx certificate that will be not valid, if you wish to use your own certificate for it update the following section in the nginx.yaml file

        nginx_config_upload_ssl_crt:
          - src: molecule/common/files/ssl/molecule.crt
            dest: /etc/ssl/certs
            backup: true
        nginx_config_upload_ssl_key:
          - src: molecule/common/files/ssl/molecule.key
            dest: /etc/ssl/private
            backup: true

To install and configure nginx run

ansible-playbook -i ./inventory.yaml ./nginx.yaml -D

This will install nginx on the prometheus host, idea is that communication between your HAproxy and Prometheus instance is also encrypted. The Valid certificate should be on the HAproxy. It's optional to have a valid certificate on the internal nginx. You can without worry use a internal CA for nginx.

Prometheus

Copy the targets file, uncomment everything and add your nodes to either the rpcor bootnodesection.

cp ./group_vars/prometheus/targets_template.yaml ./group_vars/prometheus/targets.yaml

Install and configure Prometheus

ansible-playbook -i ./inventory.yaml ./prometheus.yaml -D

Next steps

• configure HAproxy
• create rules to only allow the federation server to access your instance
• Do a PR to append your prometheus instance to the list in ibpfederation job here
