Create a highly available k3s cluster with external datastore

Prereqs

For this particular setup we will need 3 machines to act as kubernetes (k3s) masters and one machine to act as a datastore

The datastore will be a mysql (mariadb) server although you can choose different options

The operating system chosen for this task is Debian 11 (theoretically the setup can be performed on any linux machine)

k3s etcd commands

etcd

Setup etcdctl using the instructions at https://github.com/etcd-io/etcd/releases/tag/v3.4.13 (changed path to /usr/local/bin):

Note: if you want to match th etcdctl binaries with the embedded k3s etcd version, please run the curl command for getting the version first and adjust ETCD_VER below accordingly:

curl -L --cacert /var/lib/rancher/k3s/server/tls/etcd/server-ca.crt --cert /var/lib/rancher/k3s/server/tls/etcd/server-client.crt --key /var/lib/rancher/k3s/server/tls/etcd/server-client.key https://127.0.0.1:2379/version

Настройка сервера Angie

Angie (Энджи) — эффективный, мощный и масштабируемый веб-сервер, реализованный как форк nginx:

Создан бывшими разработчиками исходного проекта, чтобы двигаться в новом направлении, и может служить заменой предшественнику без переработки конфигурации и модулей.
Включает все возможности nginx 1.27.4 и добавляет к ним целый ряд новых функций.

Установка Angie на сервер Ubuntu или Debian

На основе официальной документации: https://angie.software/angie/docs/installation/

Установка сертификатов НУЦ Минцифры в Alpine Linux

Проверяем:

curl -vvv -XGET -I https://www.sberbank.ru/ru/certificates

Prometheus exporter for NGINX Unit metrics

The NGINX Unit control API includes a /status endpoint for usage statistics. This is a solution for exposing these metrics in Prometheus format.

The application (run by Unit) queries the /status URI on the control socket and converts the JSON response into Prometheus text format. PHP and Python implementations are available.

These instructions assume an existing Unit installation with a working configuration. We will add a new listener on the default prometheus port (9090) and route it directly to the Prometheus app.

Step 0. Install the preferred Unit language module (unit-php or unit-python)

	// Database connection
	$db = JFactory::getDBO();
