we can launch random stuff, but this isn't repeatable
kubectl create deploy nginx --image=nginx:1.16-alpine
kubectl get deploy
kubectl get po
kubectl delete deploy/nginx
launch again using kustomize templates
kubectl create deploy nginx --image=nginx:1.16-alpine --dry-run -o yaml > deployment/base/deployment.yaml
kubectl apply -k deployment/base
kubectl get deploy
kubectl get po
describe pod, look at the image
scale deployment manually
kubectl scale deploy/nginx --replicas=3
kubectl rollout status deploy/nginx
kubectl get deploy
kubectl get po kubectl set image deploy/nginx nginx=nginx:1.17-alpne --record
kubectl rollout status deploy/nginx
kubectl get po
kubectl rollout undo deploy/nginx
redo upgrade from manifest
kustomize build deployment/base
edit base to change image and then apply
kubectl apply -k deployment/base
how can we use this for different environments?
kustomize build deployment/overlay/staging
kustomize build deployment/overlay/production
kubectl apply -k deployment/overlay/staging
kubectl apply -k deployment/overlay/production
kubectl get deploy
kubectl get pods
show services listening as NodePort
go look at them
curl -I training-a:< port>
show deployment/overlay/ingress/single/ingress.yaml
kubectl apply -k deployment/overlay/ingress/single
kubectl get ingress kustomize build deployment/overlay/ingress/fanout
kubectl apply -k deployment/overlay/ingress/fanout kustomize build rancher-demo/base
kubectl apply -k rancher-demo/base docker run -d --restart=unless-stopped -p 80:80 -p 443:443 -v /opt/rancher:/var/lib/rancher rancher/rancher:v2.3.4

show workloads on running cluster
edit them / delete them
redeploy monachus/rancher-demo as a workload
put an Ingress in front of it
use training-a.cl.monach.us
scale it
