Study Notes

Ingress Requirements

  • Tanzu needs an ingress controller to expose services to external clients.
  • Ingress controllers route external requests to the appropriate service within the workload domain.
  • Common ingress controllers include Traefik, Nginx Ingress Controller, and Ambassador.
  • Ingress configurations define rules mapping hostnames and paths to specific services.
  • Configurations can define TLS encryption for secure communication.
  • Ingress must be accessible from outside the workload domain (e.g., using an external load balancer or service).
  • Firewall rules must allow network traffic between the external and ingress components.
  • Ingress integration with Cloud Foundry ensures proper routing and security.

Egress Requirements

  • Egress allows Tanzu workloads to access external resources (databases, APIs, etc.).
  • Proper configuration is needed for egress traffic to reach external endpoints.
  • Configuration involves specifying destination endpoints.
  • Security of egress routes is crucial.
  • Correct firewall rules are needed for outgoing traffic from the Cloud Foundry environment.
  • Cloud Foundry DNS and reverse-proxy settings are important for external service endpoints.
  • Connectivity through cloud provider infrastructure is needed.
  • Network policies are often needed for egress routing.
  • Workloads need access to external network components (e.g., DNS resolution).
  • Policies must prioritize security by limiting authorized traffic.

Connection Considerations

  • Secure connections are essential for both ingress and egress.
  • Trust relationships between the workload domain and external systems are needed.
  • Encryption, authentication, and authorization are crucial components (often involve certificate management).
  • Security groups and networking components must be properly configured.
  • Configuration should align with wider cloud provider security policies.
  • Connection methods depend on ingress/egress controllers and target applications.
  • Consistent security policies across services are essential.

Network Policies and Management

  • Network policies control ingress and egress traffic flows.
  • Defining rules for application traffic and service communication is crucial.
  • Security and access control prevent unauthorized access.
  • Policy management and updates are needed in dynamic environments.
  • Properly implemented policies ensure security and limit external connections.
  • Monitoring and maintenance of policies ensure security posture.
  • Policies must be adjusted for changing application needs.

Cloud Provider Considerations

  • Cloud providers dictate networking specifications and resources for ingress and egress.
  • Leverage cloud provider resources (load balancers, firewall rules) for improved flexibility and scalability.
  • Cloud provider-specific components are needed.
  • Cloud provider resources and constraints should be integrated into Tanzu designs.
