It would be good to add a healthcheck to the postgres/README.md.

There are some possible starting points posed here: https://stackoverflow.com/questions/65115627/safe-ways-to-specify-postgres-parameters-for-healthchecks-in-docker-compose

Aside: running the below:

--- version: "3.8" services: postgres: image: postgres:latest environment: POSTGRES_USER: user POSTGRES_PASSWORD: pass POSTGRES_DB: db

docker compose up postgres --detach docker compose run postgres pg_isready --username user --dbname db

I can never get pg_isready to output something besides /var/run/postgresql:5432 - no response
