Self-Hosted Databases

12 stacks for anyone who wants a managed database without the managed-database bill. Each one is a vanilla compose.yaml that runs locally with docker compose up, with a measured RAM footprint and a one-step deploy to Miget from $7/month flat.

#what each one needs

RAM and disk are what the compose file allocates, not guesses, and the plan is the smallest one that holds it. Databases and caches come managed and included on Miget rather than billed per instance.
