Azure AKS Cluster Access with Multiple Clusters¶

Step-01: Introduction¶

Azure AKS Cluster Access
Create Clusters using Command Line
Understand kube config file $HOME/.kube/config
Understand kubectl config command
kubectl config view
kubectl config current-context
kubectl config use-context

Step-02: Create AKSDEMO3 cluster using AKS CLI¶

Generates SSH Keys with option --generate-ssh-keys
They will be stored in $HOME/.ssh folder in your local desktop

Backup them if required

# Create AKSDEMO3 Cluster
az group create --location centralus --name aks-rg3
az aks create --name aksdemo3 \
              --resource-group aks-rg3 \
              --node-count 1 \
              --enable-managed-identity \
              --generate-ssh-keys

# Backup SSH Keys
cd $HOME/.ssh
mkdir BACKUP-SSH-KEYS-AKSDEMO-Clusters
cp id_rsa* BACKUP-SSH-KEYS-AKSDEMO-Clusters
ls -lrt BACKUP-SSH-KEYS-AKSDEMO-Clusters

Step-03: Create AKSDEMO4 cluster using AKS CLI¶

Use same SSH keys for AKSDEMO4 cluster using --ssh-key-value

# Create AKSDEMO4 Cluster
az group create --location centralus --name aks-rg4
az aks create --name aksdemo4 \
              --resource-group aks-rg4 \
              --node-count 1 \
              --enable-managed-identity \
              --ssh-key-value /Users/kalyanreddy/.ssh/id_rsa.pub

Step-04: Configure AKSDEMO3 Cluster Access for kubectl¶

Understand commands
kubectl config view

kubectl config current-context

# View kubeconfig
kubectl config view

# Clean existing kube configs
cd $HOME/.kube
>config
cat config

# View kubeconfig
kubectl config view

# Configure AKSDEMO3 & 4 Cluster Access for kubectl
az aks get-credentials --resource-group aks-rg3 --name aksdemo3

# View kubeconfig
kubectl config view

# View Cluster Information
kubectl cluster-info

# View the current context for kubectl
kubectl config current-context

Step-05: Configure AKSDEMO4 Cluster Access for kubectl¶

# Configure AKSDEMO4 Cluster Access for kubectl
az aks get-credentials --resource-group aks-rg4 --name aksdemo4

# View the current context for kubectl
kubectl config current-context

# View Cluster Information
kubectl cluster-info

# View kubeconfig
kubectl config view

Step-06: Switch Contexts between clusters¶

Understand the kubectl config command use-context

# View the current context for kubectl
kubectl config current-context

# View kubeconfig
kubectl config view 
Get contexts.context.name to which you want to switch 

# Switch Context
kubectl config use-context aksdemo3

# View the current context for kubectl
kubectl config current-context

# View Cluster Information
kubectl cluster-info
