 First we need to pull down the container image, we'll use Postgres 17, check out the [Postgres Version Policy](../../overview/versioning-policy.md#postgresql-releases) to learn which versions are supported.
 
 ```shell
-docker pull postgres:17.0-trixie
+docker pull postgres:17-bookworm
 ```
 
 Then we just need to start up the container.
 
 ```shell
-docker run -d --name postgres --restart=always -p 5432:5432 -e POSTGRES_PASSWORD=<secret> postgres:17.0-trixie
+docker run -d --name postgres --restart=always -p 5432:5432 -e POSTGRES_PASSWORD=<secret> postgres:17-bookworm

   postgres:

+    image: postgres:17-bookworm
     environment:
       POSTGRES_USER: postgres
       POSTGRES_PASSWORD: <secret>
