Kubernetes - Nginx Exposed With Loadbalancer

The first thing I tried doing in my effort to learn more about Kubernetes (using LKE, specifically) was to create a default NGINX page and expose it via a LoadBalancer (NodeBalancer). I had no idea how to go about this, initially. I eventually figured out, though, how to accomplish this using YAML files I found on the kubernetes.io website, as well as from a random YouTube video, which was helpful. What I am only now just realizing is that this can literally be done in two steps (without YAML files):

Adding a Persistent Volume to My Kubernetes Cluster

I added a PVC, then updated my deployment file to add the mount point and volume info. volumeMounts: - mountPath: "/mnt/data/images" name: nothing-volume volumes: - name: nothing-volume persistentVolumeClaim: claimName: nothing-pvc However, that didn’t work. According to my pod logs, the volume couldn’t attach because it was already attached to a different pod. I think that’s because I have 3 replicas. When I rolled out the new deployment, one of the pods just hung out in ContainerCreating:

Getting more familiar with Kubernetes and LKE (Linode Kubernetes Engine)

A few weeks ago I started studying Kubernetes using the Certified Kubernetes Administrator course in O’Reilly (by Sander Van Vugt). We started offering LKE (Linode Kubernetes Engine) at Linode in Spring of 2020, and it’s been a thorn in my side not understanding it well enough, being in Customer Support. It’s true that the only portion of LKE that’s “Managed” is the Control Plane. However, I didn’t feel I knew enough about Kubernetes to understand the difference between what we manage and what was the customer’s responsibility.

Following inspiration

I recently started reading “Knowing Where to Look” by Light Watkins. He quotes the dictionary definition of Inspiration. “The process of being mentally stimulated to do or feel something, especially something creative.” The exact opposite of how I’ve been feeling for I don’t know how long. Uninspired. Mentally unstimulated. Feeling nothing, with no creative pulse. Dense and thick. He also references this quote from Anaïs Nin. “Life is a process of becoming, a combination of states we have to go through.
