Compliance requirements (PCI-DSS, HIPAA)
Multi-cluster secure communication

Core Concepts

1. mTLS Flow

┌─────────┐                              ┌─────────┐
│ Service │                              │ Service │
│    A    │                              │    B    │
└────┬────┘                              └────┬────┘
     │                                        │

└─────────┘                              └─────────┘

2. Certificate Hierarchy

Root CA (Self-signed, long-lived)
    │
    ├── Intermediate CA (Cluster-level)
    │       │
    │       ├── Workload Cert (Service A)
    │       └── Workload Cert (Service B)
    │
    └── Intermediate CA (Multi-cluster)
            │
            └── Cross-cluster certs

Best Practices

Do's

Start with PERMISSIVE - Migrate gradually to STRICT
Monitor certificate expiry - Set up alerts
Use short-lived certs - 24h or less for workloads
Rotate CA periodically - Plan for CA rotation
Log TLS errors - For debugging and audit

Don'ts

Don't disable mTLS - For convenience in production
Don't ignore cert expiry - Automate rotation
Don't use self-signed certs - Use proper CA hierarchy
Don't skip verification - Verify the full chain

Excalidraw Diagram Generator

by github

vendor ×3

Generate Excalidraw diagrams from natural language descriptions. Use when asked to "create a diagram", "make a flowchart", "visualize a process", "draw a system architecture", "create a mind map", or "generate an Excalidraw file". Supports flowcharts, relationship diagrams, mind maps, and system architecture diagrams. Outputs .excalidraw JSON files that can be opened directly in Excalidraw.
