⁠Pulling

docker pull readystack/postgresql:18.4-CE-debian-bookworm-r1

⁠Deployment

Single container. A self-contained PostgreSQL 18.4 object-relational database server, compiled from source (./configure && make world-bin && make install-world-bin). The image IS the complete running instance — PostgreSQL itself IS the database, so there is NO external database and NO sidecar. On first boot the entrypoint runs initdb to create the cluster under PGDATA (/var/lib/postgresql/data), then runs postgres in the foreground. Runs fully NON-ROOT as the postgres user.

docker run -d --name postgresql -e POSTGRES_PASSWORD=YOUR_SECRET -p 5432:5432 -v pgdata:/var/lib/postgresql/data readystack/postgresql:18.4-CE-debian-bookworm-r1
