Real world DevOps project from start to finish

DevOps for startups and individuals | Docker, LXC, GitLab, CI/CD, Ansible, certbot, WireGuard, mail, Traefik, Pi-hole

This course will cover a DevOps project from its inception all the way to a finished product.

It is aimed at startups, small companies, and individuals who want to self-host their infrastructure.

We will combine multiple tools and services to produce a working, easily reproducible server which can support a small company.

Ansible - to configure the server and deploy services.
Let's Encrypt (certbot) - to obtain wildcard TLS certificate with auto renewal.
VPN (WireGuard) - for secure access to our services.
Docker with docker-compose - to easily deploy our applications and services.
MariaDB - MySQL fork.
LXC (Linux containers) - another virtualization technology.
iRedMail - mail server which we'll use to send and receive notifications.
Zulip - an open source chat and collaborative software which can be self-hosted (alternative to Slack or Microsoft Teams).
Traefik (reverse proxy and TLS termination proxy) with Docker and file providers - a single entry point for our services with automatic TLS certificates.
Pi-hole - ad blocking on DNS level.
Nextcloud - Email, calendar, documents, photos...It even has built-in code editor.
checkmk - monitoring solution.
Borg with borgmatic - backup solution.
GitLab - Git server, CI/CD, GitLab Container Registry, etc.
backup-checker - with this project we will showcase everything we've created!
We'll create a Python program which will compare finished backups with the desired list of backups, use GitLab CI/CD to create Docker image, push it to our own, private Docker Registry, run it on our server via GitLab Runner, and send notification to our Zulip server.
Upgrade scripts for services running in Docker.
Upgrading iRedMail.
Upgrading Zulip.
Upgrading host OS.
