 2. Start a container using the [Postgres image](https://hub.docker.com/_/postgres) with the following command:
 
     ```console
-    $ docker run --name=db -e POSTGRES_PASSWORD=secret -d -v postgres_data:/var/lib/postgresql/data postgres
+    $ docker run --name=db -e POSTGRES_PASSWORD=secret -d -v postgres_data:/var/lib/postgresql postgres
     ```

 8. Start a new container by running the following command, attaching the same volume with the persisted data:
 
     ```console
-    $ docker run --name=new-db -d -v postgres_data:/var/lib/postgresql/data postgres 
+    $ docker run --name=new-db -d -v postgres_data:/var/lib/postgresql postgres
     ```
 
     You might have noticed that the `POSTGRES_PASSWORD` environment variable has been omitted. That’s because that variable is only used when bootstrapping a new database.
