Day 1 of #100daysofhomelab

I have decided to start my #100daysofhomelab journey again, so today is day 1. I have been working on a K3s cluster in the house, and so far, I have to start again… going to rebuild it again tomorrow at some stage…

Lots of Links

some notes for myself:

Service Account for Dashboard

to create the Service account, create a file, ca.yml, and enter the following:

apiVersion: v1
kind: ServiceAccount
  name: <username>
  namespace: kube-system

next, create a file called cluster-role-binding.yml with the following:

apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
  name: <username>
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
- kind: ServiceAccount
  name: <username>
  namespace: kube-system

make sure username matches!

run the following commands:

kubectl apply -f sa.yml
kubectl apply -f cluster-role-binding.yml
kubectl -n kube-system create token <username>
