GCP Google Kubernetes Engine Access to Multiple Clusters
Implement GCP Google Kubernetes Engine Access to Multiple Clusters

Step-00: Pre-requisites

  • We should have the two clusters created and ready
  • standard-cluster-private-1
  • autopilot-cluster-private-1

Step-01: Introduction

  • Configure access to Multiple Clusters
  • Understand kube config file $HOME/.kube/config
  • Understand kubectl config command
    • kubectl config view
    • kubectl config current-context
    • kubectl config use-context
    • kubectl config get-context
    • kubectl config get-clusters

Step-02: Pre-requisite

  • Verify if you have any two GKE Clusters created and ready for use
  • standard-cluster-private-1
  • autopilot-cluster-private-1

Step-03: Clean-Up kube config file

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

Step-04: Configure Standard Cluster Access for kubectl

  • Understand commands
    • kubectl config view
    • kubectl config current-context
# View kubeconfig
kubectl config view

# Configure kubeconfig for kubectl: standard-cluster-private-1 
gcloud container clusters get-credentials standard-cluster-private-1 --region us-central1 --project kdaida123

# View kubeconfig
kubectl config view

# View Cluster Information
kubectl cluster-info

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

Step-05: Configure Autopilot Cluster Access for kubectl

# Configure kubeconfig for kubectl: autopilot-cluster-private-1
gcloud container clusters get-credentials autopilot-cluster-private-1 --region us-central1 --project kdaida123

# 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 gke_kdaida123_us-central1_standard-cluster-private-1

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

# View Cluster Information
kubectl cluster-info

Step-07: List Contexts configured in kubeconfig

# List Contexts
kubectl config get-contexts

Step-08: List Clusters configured in kubeconfig

# List Clusters
kubectl config get-clusters
