When a Citadel Agent sends a certificate signing request to Citadel to get a certificate for a workload instance, it includes the JWT that the Kubernetes API server issued representing the service account of the workload instance. This is the main repository that you are currently looking at. Taking advantage of Kubernetes trustworthy JWTs to issue certificates for workload instances more securely. Using this service registry, the Envoy proxies can then direct traffic to the relevant services. istio-system. A service mesh helps you manage and configure the interactions between them. The openstack cloud-provider can use the openstack LBaaS API to create loadbalancers and add/remove VIP endpoints corresponding to kubernetes loadbalancer service types. I was also intrigued to find complete teams focused on those features. Visualizing Istio Service Mesh Patterns with Kiali Kiali is an open source project that works with Istio to visualize the service mesh topology.
