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