Self-install kubernetes dashboard on DOKS using helm3

gistfile1.txt

# Requires that you have helm3 installed on your local machine and cluster is accessible (kubeconfig).
# You do NOT need the following instructions, if you are comfortable using helm!!


# Reference: https://github.com/kubernetes/dashboard/releases/tag/v3.0.0-alpha0
# Helm Instructions: https://artifacthub.io/packages/helm/k8s-dashboard/kubernetes-dashboard
# Dashboard 3.0 alpha version is supported on k8s 1.27 only. However we will go ahead and install on 1.28.


# Verify your DOKS k8s version
(bash) ~ kubectl version --short
Flag --short has been deprecated, and will be removed in the future. The --short output will become the default.
Client Version: v1.27.2
Kustomize Version: v5.0.1
Server Version: v1.28.2
(bash) ~


(bash) ~  helm repo add kubernetes-dashboard https://kubernetes.github.io/dashboard/

(bash) ~ helm upgrade --install kubernetes-dashboard kubernetes-dashboard/kubernetes-dashboard --create-namespace --namespace kubernetes-dashboard --set app.ingress.enabled=false --set metrics-server.enabled=false --set cert-manager.enabled=false --set nginx.enabled=false



# Now do the port-forwarding to your local machine, so you can access the dashboard from your local browser
(bash) ~ export POD_NAME=$(kubectl get pods -n kubernetes-dashboard -l "app.kubernetes.io/name=kubernetes-dashboard,app.kubernetes.io/instance=kubernetes-dashboard" -o jsonpath="{.items[0].metadata.name}")

(bash) ~ echo $POD_NAME
kubernetes-dashboard-65f476df89-886k8

(bash) ~   kubectl -n kubernetes-dashboard port-forward $POD_NAME 8443:8443


# Kubernetes Dashboard URL on your local machine: https://127.0.0.1:8443/

# At this point, we can connect to dashboard from our local browser. There will be a certificate warning, so make sure to override that.
# When connecting to dashboard, it will require the kubernetes auth credentials for your cluster. Make sure to download the kubernetes configuration file for your cluster from DOKS cloud console. 

# The dashboard installed does not have a public endpoint. If you need one, then you will need to install nginx, cert-manager and configure the values.yaml file as part of installation


############################


# If you want to reinstall the dashboard with updated configuration of your choice, do the following.

# Download the package details
(bash) ~ helm repo update
(bash) ~ helm search repo kubernetes-dashboard
(bash) ~ helm pull kubernetes-dashboard/kubernetes-dashboard --untar

# The above command should download the package and keep in kubernetes-dashboard folder in the current directory. Update the values.yaml to your choice. Then do a helm upgrade.
# Note that the values.yaml file retrieved here does not seem to have cert-manager configuration! You may like to retrieve the latest values.yaml from https://artifacthub.io/packages/helm/k8s-dashboard/kubernetes-dashboard (look for default values in the right menu).

(bash) ~ helm ls
(bash) ~ helm upgrade --install kubernetes-dashboard kubernetes-dashboard/kubernetes-dashboard --create-namespace --namespace kubernetes-dashboard

# The above should have your dashboard upgraded with new configurations from values.yaml


# If you want to remove the helm chart, use helm uninstall
(bash) ~ helm uninstall kubernetes-dashboard -n kubernetes-dashboard
