Sprint 02 review

Welcome back! In this lesson, we recap Sprint 02, where we focused on:

What We Achieved

1. GCP Account Setup

   • Registered for a Google Cloud Platform account.
   • Enabled billing and configured IAM permissions.

2. GKE Fundamentals

   • Explored key concepts: nodes, pods, control plane, and networking.
   • Reviewed GKE-specific features like auto-scaling and regional clusters.

3. Cluster Provisioning

   • Created a GKE cluster using the gcloud CLI.
   • Retrieved credentials and verified the cluster’s health.

Essential gcloud & kubectl Commands

# Authenticate with GCP
gcloud auth login

# Set your project ID
gcloud config set project YOUR_PROJECT_ID

# Create a GKE cluster in us-central1-a
gcloud container clusters create my-cluster \
  --zone us-central1-a \
  --machine-type e2-medium \
  --num-nodes 3

# Retrieve cluster credentials for kubectl
gcloud container clusters get-credentials my-cluster \
  --zone us-central1-a

# Verify node status
kubectl get nodes

Key Takeaways

• Defining sprint tasks is just the starting point; dive into related subtasks (e.g., authentication, IAM) for a deeper understanding.
• Hands-on practice with gcloud and kubectl cements your GKE workflow.
• Validating cluster connectivity early prevents common deployment headaches.

Next Steps: Sprint 03 Preview

In Sprint 03, we will:

• Deploy a sample application using a Kubernetes Deployment and Service.
• Scale workloads with the Horizontal Pod Autoscaler.
• Perform rolling updates to achieve zero-downtime releases.
