Lab notes for Lab 8 - Lab: Building Cloud-Native Applications for OpenShift are incorrect.

The lab notes for Lab 8 - Lab: Building Cloud-Native Applications for OpenShift are incorrect. . The Lab states;

A tododb service exists in your OpenShift project that connects to an external database. To obtain the FQDN of the external database, replace apps in your OpenShift cluster wildcard domain with mysql. For example, if the wildcard domain of your cluster is apps.cluster.domain.example.com, then the database FQDN is mysql.cluster.domain.example.com.

Thus taking my own lab as an example the mysql server would be at the url;
$ set | grep WILDCARD
RHT_OCP4_WILDCARD_DOMAIN=apps.eu46.prod.nextcle.com
$ MYSQL_DB=mysql.eu46.prod.nextcle.com

However this host then fails in the following mysql command
$ mysql -u -p -h${MYSQL_DB}

In the Solution element of the lab we see the command
MYSQL_DB=$(echo
mysql.ocp-${RHT_OCP4_WILDCARD_DOMAIN#"apps."})

Which adds a .ocp- element to the url. Once this is added the mysql command works. So the lab guide is in correct and should suggest to add msql.ocp-{your WILDCARD cluster domain (minus the apps )}

Open the Lab 8 notes at the linked course page and compare the database hostname instructions with the Solution element. Verify the working MYSQL_DB command shown in the issue, then update the lab text so the documented hostname matches the successful mysql invocation.
