Step 1. How to set AKS Cluster in Azure This step could reference the official documents as below,
https://docs.microsoft.com/en-us/azure/aks/kubernetes-walkthrough-portal
Step 2 Open the could shell
The link as https://shell.azure.com/
And input the Command as below
1
az aks get-credentials --resource-group AKSGroup --name AKSCluster
Step 3 install Prometheus How to create change nampspace :
1
2
kuebctl create ns monitoring
kubectl config set-context --current --namespace= monitoring
The install command as below,
1
helm install stable/prometheus --name kube-prometheus --set rbac.create= true --namespace monitoring
If you met the issue like
Error: namespaces “monitoring” is forbidden: User “system:serviceaccount:kube-system:default” cannot get resource “namespaces” in API group "” in the namespace “monitoring”

kubectl create -f rbac-config.yaml
helm init --service-account tiller --history-max 200
Step 4 install Grafana 1
helm install stable/grafana --set persistence.enabled= true --set persistence.accessModes={ ReadWriteOnce} --set persistence.size= 8Gi -n grafana --namespace monitoring
You can mark the service as LoadBalancer,
1
kubectl edit svc grafana
Get the password,
1
kubectl get secret --namespace monitoring grafana -o jsonpath = "{.data.admin-password}" | base64 --decode ; echo
step 5 Access the Kubernetes web dashboard in AKS The shell script as below.
1
az aks browse --resource-group AKSGroup --name AKSCluster
For RBAC-enabled clusters.
1
kubectl create clusterrolebinding kubernetes-dashboard --clusterrole= cluster-admin --serviceaccount= kube-system:kubernetes-dashboard
setp 6 install traekit install htpasswd.
1
apt-get install apache2-utils
generate password.
1
htpasswd -nbm admin password1234
install traefik.
1
helm install stable/traefik --set dashboard.enabled= true,serviceType= LoadBalancer,rbac.enabled= true,dashboard.auth.basic.admin= '$apr1$ZywpxeoS$6U80kYPG116slxBceEsVz0' ,dashboard.domain= traefik.dashboard --name= traefik --namespace= kube-system
helm delete.
1
helm del --purge traefik
step 7 install kubeapps 1. Install Kubeapps.
1
kubectl create namespace kubeapps
1
helm repo add bitnami https://charts.bitnami.com/bitnami
Helm 2 command
1
helm install --name kubeapps --namespace kubeapps bitnami/kubeapps
Helm 3 command
1
helm install kubeapps --namespace kubeapps bitnami/kubeapps --set useHelm3 = true
2. Create a Kubernetes API token.
Create service account,
1
kubectl create serviceaccount kubeapps-operator -n kubeapps
Create cluster role binding,
1
kubectl create clusterrolebinding kubeapps-operator --clusterrole= cluster-admin --serviceaccount= kubeapps:kubeapps-operator
Get the secret,
1
kubectl get secret -n kubeapps $( kubectl get serviceaccount kubeapps-operator -n kubeapps -o jsonpath = '{.secrets[].name}' ) -o jsonpath = '{.data.token}' | base64 --decode && echo
