The capstone: from repository to production
The whole curriculum on one machine: build a production service, break it, restore it, and prove it holds.
"It works" is not "it is done". This capstone assembles what every course taught — accounts, systemd, Nginx, the firewall, backups, monitoring, deployment — into one production service with five properties you can prove: it survives a reboot, it survives its own crash, it rolls back in one command, it tells someone when it breaks, and its backup restores.
What you will be able to do
- Order the build of a complete hosting setup, and justify that order
- Assemble the service account, systemd unit, Nginx vhost and firewall without re-learning any of them
- Handle a release incident: roll back first, diagnose second
- Prove — not assert — that a service is monitored, backed up and reversible
Outline
- 01
From zero to serving
The plan, its order, then the build — every step pointing back at the course that taught it.
- 02
Day two: prove it still works
A release incident, then the audit of the five proofs.
