Expose and secure kyma workloads with client certificates and kyma-system defined mTLS gateways

2. Expose and secure kyma workloads with client certificates and kyma-system defined mTLS gateways

The following kyma tutorial details a number of pre-requisite steps, namely:
  • having a dedicated custom domain for mTLS communication with a mutual TLS gateway
  • and creating a cacert bundle for the server side certificate validation.
However, any managed kyma cluster domain is also a custom domain (and managed by SAP).

Thus, it is possible to reuse this kyma cluster domain "as is" by adding a dedicated mutual TLS gateway.
