Multi-Container Pods and the “Why didn’t I know this sooner?” Moment I went in for a marathon session Thursday studying for the CKA certification, and I’m still buzzing—especially after digging into multi-container Pods. Seeing how Pods handle multiple containers was really interesting, and the scheduling + logging sections were a highlight. There’s a lot of power here, and it clicked
We are talking Kubernetes of course. Got to love the quirky IT naming conventions. Once you dig into the concepts behind the naming it all starts to make sense. Today I learned about Node Affinity to control where your pods get deployed onto nodes as well DaemonSets, Taints and Tolerations. Well, you can keep the “flys” away (stray pods) from

The lab modules seem easy to solve (so far),
Latest lesson services and their port definitions and end points. Here is a quick diagram of the Service Ports and End Ports. Services are needed in the cluster to enable a single point of entry by name vs. IP Address. Since Container Pods come and go as well as moving to different Nodes, using an internal cluster IP Address is
