A member of a Slack channel I frequent recently asked how you go about patching existing Kubernetes resources. After responding, I thought that others might benefit from the same information. In today’s example, we’re going to resize a PersistentVolumeClaim (PVC).

How I Passed the CKA
After passing the CKAD at the end of 2019, I was amped and ready to knock out the CKA. I was ready to take the exam in March and then all hell broke loose. 2020 is the year of Covid and nothing seems to be working out as expected. Fast forward to November and I decided it was finally time to get back to it. So, what did I do this time around?
How I Passed the CKAD Exam
Updated 12/2020
Last year, I decided that since I’d been working on pushing my employer to embrace a Cloud-native mentality that I should lead by example and get certified. We had chosen Kubernetes as our base container management platform and ultimately inked a deal with Red Hat to roll out OpenShift throughout the enterprise.
If you’ve read the blog for any time, you’ll remember that I was originally pursuing RHEL certification. At the time, even though I was in a development role, I was finding myself needing more and more Linux skills. However, my role transitioned to a dedicated focus on Cloud technologies. I abandoned RHEL and began focusing on Kubernetes. However, it wasn’t until about November of this year that I really buckled down to prepare.
In the spirit of openness, I’ll confess that I’ve had the benefit of spending the past several months working in a dedicated fashion deploying multiple OpenShift clusters. This has involved a great deal of tweaking, testing, and troubleshooting which has provided invaluable real-world, hands-on experience working with the Kubernetes system. Now, with that out of the way, I thought I’d share my personal take on how I prepared…and passed…the CKAD exam.
