Using HashiCorp Vault as Ingress TLS Certificate Issuer in TAP

Tanzu Application Platform (TAP) uses Contour HTTPProxy resources to expose several web components externally via ingress. Some of these components include the API Auto Registration, API Portal, Application Live View, Metadata Store, and TAP GUI. Web workloads deployed through TAP also leverage the same method for their ingress resources. For example:

$ kubectl get httpproxy -A

TAP uses a shared ingress issuer as a centralized certificate authority representation, providing a method to set up TLS for the entire platform. All participating components get their ingress certificates issued by it. This is the recommended best practice for issuing ingress certificates on the platform.

Getting Started with Carvel ytt - Real-World Examples

2023-01-01 11 min read Carvel Cloud Native Kubernetes Tanzu TAP TKG

Over the years of working with Tanzu Kubernetes Grid (TKG), one tool has stood out as a game-changer for resource customization: Carvel’s ytt. Whether tailoring cluster manifests, customizing TKG packages, or addressing unique deployment requirements, ytt has consistently been a fundamental part of the workflow. Its flexibility, power, and declarative approach make it an essential tool for anyone working deeply with Kubernetes in a TKG ecosystem.

But what exactly is ytt? Short for YAML Templating Tool, ytt is part of the Carvel suite of tools designed for Kubernetes resource management. It provides a powerful, programmable approach to templating YAML configurations by combining straightforward data values, overlays, and scripting capabilities. Unlike many traditional templating tools, ytt prioritizes structure and intent, making it easier to maintain, validate, and debug configurations—particularly in complex, large-scale Kubernetes environments.
