DO180 4.5 two pods created

Jump to solution

Hi All,

ch06s04 step 3.2

The book says:

List the pods in this project to verify that the MySQL pod is ready and running:

[student@workstation ~]$ oc get pods -o=wide NAME READY STATUS ... NODE mysql-openshift-1-glqrp 1/1 Running ... ip-10-0-148-115.ec2.internal

 

I get:

What is this second -deploy pod for and why it is not mentioned in the book?

Hi Theo

That is the so-called "deployment pod". 

This is automatically created by OpenShift, and its purpose is to get everything ready for the deployment process to run. In this case, it makes sure the "mysql-57-rhel7" is available and creates the deploymentConfig resource. 

I can't tell you a definitive answer about why it is not mentioned in the book (probably it should!), but a plausible reason is that DO180 is an introductory course. Getting too deep into the way OpenShift implements different types of deployments may confuse students, and probably it is best suited for more advanced courses.

Anyway, and as you said, it is worth at least mentioning that the existence of this container is expected. I'll add a note to the development team.

Thanks a lot for the feedback!
