kind setup

kind.txt

1. install kind:
  go or go1.20.3 install sigs.k8s.io/[email protected]


2. create a 3-node worker cluster by creating a yml file like this:
kind: Cluster
apiVersion: kind.x-k8s.io/v1alpha4
nodes:
- role: control-plane
- role: worker
- role: worker

333create kubernets cluster:
  kind create cluster --name local --config <filename from #2>

3. check cluster exists:
  kind get clusters # should see "local"

4. install helm:
  macports or brew, in case of macports "sudo port install helm"

5. use helm to install kubernetes dashboard chart repo
  helm repo add kubernetes-dashboard https://kubernetes.github.io/dashboard/

6. verify repo is installed:
  helm repo list

7. use helm to deploy kubernetes dashboard
  helm install dashboard kubernetes-dashboard/kubernetes-dashboard -n kubernetes-dashboard --create-namespace

8. wait for pod to start (should be running):
  kubectl get pods -n kubernetes-dashboard  

9. start proxy:
  export POD_NAME=$(kubectl get pods -n kubernetes-dashboard -l "app.kubernetes.io/name=kubernetes-dashboard,app.kubernetes.io/instance=dashboard" -o jsonpath="{.items[0].metadata.name}")
  echo https://127.0.0.1:8443/
  kubectl -n kubernetes-dashboard port-forward $POD_NAME 8443:8443

10. open dashboard, note how there is no option to skip the login (note ignore the https cert warning for now if you see one):
  https://127.0.0.1:8443/#/login

11. create admin-user service account yml file, with the following content:

apiVersion: v1
kind: ServiceAccount
metadata:
  name: admin-user
  namespace: kubernetes-dashboard
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: admin-user
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
- kind: ServiceAccount
  name: admin-user
  namespace: kubernetes-dashboard

12. apply yml file:
  kubectl apply -f <admin-user yml filename>

13. get dashbaord token:
  kubectl create token admin-user -n kubernetes-dashboard

14. use that token to login

15. go to "nodes" in dashboard, you should see:
  local-worker
  local-worker2
  local-control-plane

16. load docker image into cluster
  kind load docker-image go_skeleton --name local

17. make sure nodes are available
  kubectl get nodes

18. start bash on a worker node:
  docker exec -ti local-worker bash

19. find the binary to make sure its actually on the node:
  find . -name <name of binary>
