Difficulty: HardDeploying and Managing Google Kubernetes Engine (GKE) Clusters and Workloads

A cloud operations team is setting up a new administrative management host to manage workloads on a newly provisioned Google Kubernetes Engine (GKE) cluster named `billing-cluster` in region `us-east4`. Arrange the following administrative and operational commands in the exact sequence required to authenticate, establish cluster context, verify cluster connectivity, and deploy a manifest named `billing-deployment.yaml`.

  1. 1Authenticate the Google Cloud CLI with valid project credentials.
  2. 2Execute `gcloud container clusters get-credentials billing-cluster --region us-east4` to generate local kubeconfig context entries.
  3. 3Execute `kubectl get nodes` to validate API server communication and cluster node readiness.
  4. 4Execute `kubectl apply -f billing-deployment.yaml` to declare and create the deployment resources.
  5. 5Execute `kubectl get pods` to inspect pod scheduling and container execution states.

Answer

The correct operational sequence begins with authenticating the gcloud CLI, followed by executing `gcloud container clusters get-credentials` to generate the local kubeconfig context, running `kubectl get nodes` to verify control plane connectivity, executing `kubectl apply -f billing-deployment.yaml` to apply the workload configuration, and concluding with `kubectl get pods` to confirm successful workload execution.
Deploying workloads to GKE from a new environment requires establishing Cloud IAM identity first, generating cluster connection entries in `kubeconfig` via `gcloud container clusters get-credentials`, testing cluster control plane responsiveness via `kubectl get nodes`, declaring resources via `kubectl apply`, and finally verifying pod runtime status with `kubectl get pods`.

Step-by-Step Solution

1
Authenticate identity with Google Cloud APIs
Active credentials are established for gcloud CLI operations
Google Cloud authentication must precede requesting cluster endpoint certificates.
2
Fetch cluster endpoint and credential info via `gcloud container clusters get-credentials`
Local `~/.kube/config` file is populated with cluster context and auth parameters
`kubectl` relies on `kubeconfig` settings populated by `gcloud container clusters get-credentials` to locate and authenticate against the GKE API server.
3
Validate cluster node reachability with `kubectl get nodes`
Confirmation that the GKE control plane responds and cluster nodes report `Ready` state
Testing API connectivity prior to deployment isolates authentication or network issues from manifest configuration errors.
4
Deploy workload manifest using `kubectl apply -f billing-deployment.yaml`
Kubernetes objects defined in the manifest are created or updated on the cluster
`kubectl apply` sends the desired state declaration to the GKE control plane.
5
Monitor container status with `kubectl get pods`
Verification that pods transition from `ContainerCreating` to `Running` state
Post-deployment inspection ensures image pull, scheduling, and health check steps complete successfully.
