Istio
The Kong Ingress Controller can be integrated with an Istio Service Mesh to use Kong Gateway as an ingress gateway for application traffic into the mesh network.
We run tests for each Kong Ingress Controller release to verify this documentation with upcoming versions of KIC and Istio. The following table lists the tested combinations:
| Kong Ingress Controller | 2.12.x | 3.0.x | 3.1.x | 3.2.x | 3.3.x | 3.4.x |
