Hopefully helped another k8s newbie with the following. The question was, how do you update a single key in a secret in k8s? I don't know anything about secrets but I will probably want to know this in the future, so here we go.

First, to create a dummy secret:

apiVersion: v1
kind: Secret
metadata:
  name: test-secret
data:

Export K8s Dashboard

kubectl proxy

If you are using local to access the dashboard:

1. Copy $HOME/.kube/config in your Master machine
2. Phase it into $HOME/.kube/config in your local machine
3. Run kubectl proxy in your local machine
4. Visit http://localhost:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy in your browser

HELM

After we installed the k8s, we would like to install helm for managing Kubernetes charts.

We can Use Helm to:

• Find and use popular software packaged as Helm charts to run in Kubernetes
• Share your own applications as Helm charts
• Create reproducible builds of your Kubernetes applications
• Intelligently manage your Kubernetes manifest files
