Section: - GUIDED EXERCISE: Working with Databases
Language: en-US (English)
Workaround: Remove the `-p 5432:5432` in step 5.3. Run the rest as written:

[student@workstation ~]$ podman run -d --name persisting-pg12 -e POSTGRESQL_USER=backend -e POSTGRESQL_PASSWORD=secret_pass -e POSTGRESQL_DATABASE=rpi-store -v rpi-store-data:/var/lib/pgsql/data --network persisting-network registry.ocp4.example.com:8443/rhel8/postgresql-12:1-113

Description: After creating the isolated network "persisting-network" there is no need for the host port mapping.  In fact, that is one of the benefits of using an isolated network with databases (to avoid exposing the database over the host network). 

The command in 5.3 should be updated so that it doesn't include `-p 5432:5432`. 

[student@workstation ~]$ podman run -d \
--name persisting-pg12 \
-e POSTGRESQL_USER=backend \
-e POSTGRESQL_PASSWORD=secret_pass \
-e POSTGRESQL_DATABASE=rpi-store \
*-p 5432:5432 *
-v rpi-store-data:/var/lib/pgsql/data \
--network persisting-network \
registry.ocp4.example.com:8443/rhel8/postgresql-12:1-113
