Kubernetes all the things

Week 1

In this introductory week we will get our hands dirty with the basics around pods: Pods are the core components of a k8s cluster. If there is something running, it is running in a pod (or a job).

Here the list of the commands that we will run:

• kubectl run hello --generator=run-pod/v1 --image speedwing/hello:latest
• kubectl get po
  • Observe fields
• kubectl get po -o wide
  • Observe pod ip, node ip
• kubectl exec -it hello bash
• kubectl port-forward hello 8080
• kubectl logs -f hello
• kubectl get po hello -o yaml
  • Metadata, spec, status
• kubectl rm po hello
• kubectl run hello --generator=deployment/apps.v1beta1 --image speedwing/hello:latest
• kubectl get deploy
  • Observe fields
• kubectl scale --replicas=3 deploy/hello
• kubectl get po -w
