Real world DevOps project from start to finish

Description

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.

We will cover:

• 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.

When you finish the course, you'll be equipped to add any additional services you need for your particular line of work.
