CKA Labs (11) — Kubernetes Services

Posted by oveits in Kubernetes, CKA

Kubernetes Services provide us with a means to load-balance between many instances of an application running on a data center. Moreover, they help make accessible the service from the Internet. Here, we will show, how PODs, endpoints, container-ports, and node ports are bound together by means of Kubwernetes Services.

CKA Labs (10) — Kubernetes DaemonSets

Posted by oveits in Kubernetes, CKA

In this blog post, we have created a Kubernetes DaemonSet. We have observed that and POD template changes are not propagated to existing PODs if we choose the OnDelete update strategy. However, if we choose the RollingUpdate strategy, POD renewal is triggered with any update of the DaemonSet's POD template.

CKA Labs (9) — Kubernetes Deployments

Posted by oveits in Kubernetes, CKA

In this blog post, we will have a closer look to Deployments, how they relate to ReplicaSets of the last post, and which features in terms of the rollout/rollback they offer to the Kubernetes administrator.
