Before the demo, verify steps 1 and 2

Slides should be referecend on all steps

• 1 - Set the cluster up

• 2 - Verify if voting-k8s dir is in the environment. If not, do: git clone https://github.com/kaiohenricunha/k8s-voting-app

• 3 - Explain K8s high-level architecture

• 4 - Explain Kubeconfig

• 5 - Explain Namespaces

• 6 - Explain Resource Quota

• 7 - Create a Namespace called 'playground': kubectl create namespace playground. If necessary, command to switch Namespace: kubectl config set-context $(kubectl config current-context) --namespace=playground / kubens playground

• 8 - Give one more example on how to access different services on different namespaces.

- 9 - Explain Pods

• 10 - Explain Deployments

• 11 - Explain StatefulSets

• 12 - Show StatefulSets in practice

• 13 - Explain Jobs

• 14 - Demonstrate Jobs:

  • kubectl create -f throw-dice-job.yaml -n playground
  • kubectl get jobs -n playground
  • kubectl get pods -n playground
  • kubectl logs nome-do-pod -n playground
  • How many attempts: kubectl describe job throw-dice-job -n playground
  • kubectl delete job throw-dice-job -n playground

• 15 - Explain Cronjobs

• 16 - Demonstrate Cronjobs:

  • kubectl create -f throw-dice-cron-job.yaml -n playground
  • kubectl get cronjob -n playground
  • kubectl describe cronjob throw-dice-cron-job -n playground
  • kubectl delete cronjob throw-dice-cron-job -n playground

• 17 - Explain Services

• 18 - Show my own Service files. Demonstration in the end.

• 19 - Show my redis svc and voting svc to exemplify ClusterIPs

• 20 - Explain Ingress

• 21 - Ingress Practice:

  • minikube addons enable ingress
  • to verify nginx: kubectl get services --all-namespaces
  • kubectl get all

• 22 - Explain ConfigMaps

• 23 - ConfigMap Practice:

  • move to the right dir and apply

• 26 - Explain Secrets

• 27 - Secrets in Practice

• 28 - Explain Volumes

• 29 - Show Volumes in Practice

• 30 - Explain PVC

• 31 - Show PVC in Practice

• 32 - Explain Custom Resources

• 33 - Show Custom Resources in Practice

• 34 - Demonstrate my application:

  • move to ingress-playground folder and apply everything(remmember to set the ClusterIP on nano. The voting-k8s folder app doesn't use Ingress)
  • then, demonstrate the application's interface
