Context
You are designing and operating services on Kubernetes in a public cloud. Answer the following to demonstrate understanding of cluster architecture, troubleshooting with kubectl, cloud service mappings across providers, and secure CI/CD design.
Tasks
- Kubernetes Architecture
- Explain the high-level architecture of a Kubernetes cluster.
- Describe control plane (master) components and worker node components, including their responsibilities and how they interact.
- kubectl Troubleshooting
- List key kubectl commands, flags, and patterns you use to debug cluster issues (nodes, pods, services, networking, rollouts). Include brief explanations and examples.
- GCP vs AWS Core Services
- Compare core computing and testing/CI services between Google Cloud Platform (GCP) and Amazon Web Services (AWS). Map common equivalents (VMs, managed Kubernetes, containers, serverless, build/test/deploy, artifact registries, security scanning).
- Secure CI/CD Design in Public Cloud
- Propose a secure CI/CD pipeline architecture suitable for deploying to Kubernetes in a public cloud.
- Cover: identity and access, secrets, artifact management and signing, build isolation, policy enforcement, environment segregation, deployment strategies, observability, and guardrails.
