Building an OpenShift LDAP URL from FreeIPA
If you want to use LDAP authentication with OpenShift, you need to build an LDAP URL from the information you do have. Here are the steps.

An earlier port hard coded the IP address and port used for MariaDB connections. I want to pull these out so I can pass them in on the command line when I create the client.

Buildah is a valuable tool in the container ecosystem. As an effort to get more familiar with it, and to finally get my hand-rolled version of Keystone to deploy on Kubernetes, I decided to work through building a couple of Keystone based containers with Buildah.

Last time I showed how to recreate a WebUI-generated MariaDB deployment from the command line. But how should you really generate it in the first place? Let’s walk through:

Web base user interfaces are great at walking a user through tasks they do not know how to perform yet. In my case, I want to launch a MariaDB instance on OpenShift. Eventually, I want to do this from the command line. Here are my steps.
Running the MariaDB Client on OpenShift
I set up a MariaDB server and wanted to test it out. There are many docs out there about how to set up the client. This is what worked for me.
First, find out the internal IP address of the Database server pod:
oc get pod -l name=mariadb -o json | jq -r '. | .items[0] | .status | .podIP ' |
In my case, that returned 10.131.0.81. Which lead to this command:
kubectl run -it --rm --image=mariadb:latest --restart=Never mariadb-client -- mysql keystone -h 10.131.0.81 --user keystone -pkeystone |
Red Hat IdM as an LDAP Identity Provider in OpenShift Container Platform 4
For my OpenShift Demo, I want to use a Red Hat IdM server as the identity provider. It took a little trial and error to get the mechanism to work right.

Cloud is easy. It is networking that is hard.
Red Hat supports installing OpenShift on OpenStack. As a Cloud SA, I need to be able to demonstrate this, and make it work for customers. As I was playing around with it, I found I could not tear down clusters due to a dependency issue with ports.

How do you add tests to a project that show a bug exists? How do you ensure that, once a bug is fixed, that fix is recorded? These questions have been present in my mind for several years. I want to use this space to explore an idea I have had for a while on how to address them.
