Kubernetes at Scale: Lessons from Banking Workloads

Running Kubernetes in a regulated financial environment adds layers of complexity that most tutorials skip.

Networking Fundamentals

Docker bridge networking and Kubernetes service meshes behave very differently under load...

Pod Design Patterns

For banking workloads, the most important patterns are:

• Sidecar containers for logging and monitoring
• Init containers for secret injection

RBAC and Security

In banking, every service account must be least-privilege. We define roles at the namespace level...

Production-Ready Checklist

• Liveness and readiness probes on every pod
• Horizontal Pod Autoscaler configured for peak load
• Network policies restricting inter-namespace traffic
• Pod disruption budgets for zero-downtime deployments
