Self-Hosting Your First Application, End to End
Taking one application from a compose file to a working service on your own server: bound to localhost, behind TLS, backed up, and alerting you when it stops. About two…
Putting a Database Somewhere Sensible
Installing PostgreSQL on your own server without leaving it open to the internet: scoped roles, socket versus TCP, dumps you have restored from, and the settings that actually matter.
