Multi Database PostgreSQL with PGBouncer

ENV file

Create a .env file with the following keys:

HOST_IP
HOST_KIND
POSTGRES_PASSWORD

Host IP

I use these with Tailscale - Use this to set the IP for Postgre to bind to.

Host Kind

In the compose.yaml, you'll see postgresql.${HOST_KIND}.conf. This lets you have custom parameters for PostgreSQL per host type. Use https://pgtune.leopard.in.ua to build your own.

CPX11 is a Hetzner host - 2 vCPUS, 2GB RAM
Nano is a Linode host - 1 vCPU, 1GB RAM

Data directory

If you're using this for Cache, per SolidCache, you may be happy to use named bind mountings and let Docker manage storage.

Alternatively, bind mount a local directory for PostgreSQL to use.
