Explore Pods

Mon, 01 Jan 0001 00:00:00 +0000

In this tutorial you build a single NGINX Pod in Kanvas, deploy it to a live cluster, expose it with a NodePort Service, and inspect the running Pod in Operator: its details, a shell inside its container, and its log stream. A Pod is the smallest unit Kubernetes schedules, and every workload controller you meet later (Deployments, StatefulSets, CronJobs) exists to create and replace Pods. Working with a bare Pod first shows you exactly what those controllers automate.

Use ConfigMaps and Secrets

In this tutorial you design a MySQL Pod that takes its database name from a ConfigMap and its root password from a Secret, deploy it to a cluster, and prove from inside the container that each value arrived. Separating configuration and credentials from the container image is how one image runs unchanged in every environment, and knowing exactly how Kubernetes delivers those values tells you why a changed setting sometimes reaches a running container and sometimes does not.
