Design first-time Kubernetes deployment in new cloud
Scenario
You are tasked with setting up a new compute cluster in a brand new cloud account/subscription (greenfield deployment). The team requires a simplified, practical plan for the initial deployment of Kubernetes and its associated platform components.
Requirements
- New Account: The cloud account is completely new, meaning no pre-existing network configurations, IAM roles, or container registries.
- Multi-Environment Support: The platform must support at least development and production environments.
- Secure by Default: Implement security measures from the outset, focusing on identity management, secrets handling, and the principle of least privilege.
- Operational Readiness: The deployment should include considerations for upgrades, observability (monitoring, logging), backups, and disaster recovery.
Questions
- What are the primary steps involved in bootstrapping the cloud account and establishing the foundational network infrastructure?
- Describe your approach to deploying Kubernetes for the first time. Would you opt for a managed service or a self-managed solution, and what are the justifications for your choice?
- How would you configure node pools, autoscaling, ingress controllers, persistent storage, and DNS resolution within the Kubernetes cluster?
- What are the critical security controls you would implement, including Identity and Access Management (IAM), Role-Based Access Control (RBAC), network policies, secret management, and image vulnerability scanning/policy enforcement?
- What Day-2 operational practices would you establish, such as monitoring, logging, alerting, cluster upgrades, and backup/restore procedures?
- How do Custom Resource Definitions (CRDs) and Operators contribute to the platform architecture and its ongoing operations?

Core dilemma
Balancing the operational overhead and complexity of a self-managed Kubernetes cluster against the potential vendor lock-in and cost of a managed service, while ensuring robust security and operability from day one in a greenfield environment.
