Steps#

1. Set a default compute zone
   • Set the default compute region

     gcloud config set compute/region "REGION"
     

   • Set the default compute zone

     1
     gcloud config set compute/zone "ZONE"
     

     NOTE

     • REGION: available region. Ex: us-central1.
     • ZONE: available zone. Ex: us-central1-a is a zone in the us-central1 region.

2. Create a GKE cluster
   • Create a cluster

     1
     gcloud container clusters create --machine-type=machine-type --zone=ZONE cluster-name
     

     NOTE

     • machine-type: available machine type. Ex: e2-medium.
     • cluster-name: cluster name.

3. Get authentication credentials for the cluster
   • Authenticate with the cluster

     1
     gcloud container clusters get-credentials cluster-name
     

4. Deploy an application to the cluster
   1. Create new deployment from a image

      1
      kubectl create deployment deployment-name --image=image-name:image-tag
      

      NOTE

      • deployment-name: deployment name.
      • image-name: image name. Ex: gcr.io/google-samples/hello-app.
      • image-tag: image tag. Ex: 1.0.

   2. Expose application

      1
      kubectl expose deployment deployment-name --type=LoadBalancer --port your-port
      

      NOTE

      • your-port: exposed port. Ex: 8080

   3. Inspect service

      1
      kubectl get service
      

5. Delete the cluster
   1. Run following command

   1
   gcloud container clusters delete cluster-name
   

   2. Type Y and Enter to confirm
