HPA check

• HPA: kubecatl get hpa [autoscaler name *optional] --watch[foreground watcher]
• Deployment: kubectl deploy [deployment name *optional] --watch [foreground watcher]

Dios for finding errors

• findout what pods services daemonsets deployments and replicasets are doing
  • kubectl -n kube-system get all

How to build

• create a kind cluster with config as config.yaml
  • kind create cluster --config=k8s-files/config.yaml --name scaling
• create rust container
  • docker build . -t rust-demo
• load docker container into the kind cluster
  • kind load docker-image rust-demo --name scaling
• apply yaml files to the cluster and watch benny's hard work
  1. kubectl apply -f scale-namespace.yaml
  2. kubectl apply -f autoscale.yaml
  3. kubectl apply -f components.yaml
  4. kubectl apply -f deployment-rust.yaml
  5. kubectl apply -f deployment-rust.yaml
• change default namespace with benny's amazing script
  • bash .namespace.sh namespace scale-namespace
• make sure you can curl and get an output
  • curl localhost:8080
• run create script in each metrics sub directory
  • alias for this in .bashrc
• portforward grafana
  • kubectl port-forward grafana-6648db4b8b-cr5xx 3000:3000 -n monitoring
  • alias for this in .bashrc
• grapha needs to be initialzed with prometheus at start
  • import dashboard 1860
  • select prometheus from the drop down near the bottom

Test

• test with hey tool
  • hey -n 1000000 -z 5s http://127.0.0.1:8080
