docker network create app-net
docker volume create pgdata
 
docker run -d \
  --name db \
  --network app-net \
  -e POSTGRES_PASSWORD=secret \
  -v pgdata:/var/lib/postgresql/18/docker \
  postgres:18
 
# local bridge network create a DNS service:
docker run --rm --network app-net alpine nslookup db
