I would recommend using Istio Ingress Controller with its core component Istio Gateway which is commonly used for enabling monitoring and routing rules features in Istio mesh services. (as a toggle). When you use an ingress controller and ingress rules, a single IP address can be used to route traffic to multiple services in a Kubernetes cluster. When the Kubernetes load balancer service is created for the NGINX ingress controller, an IP address is assigned under EXTERNAL-IP, as shown in the following example output: If you browse to the external IP address at this stage, you see a 404 page displayed.

Istio has a very powerful and flexible model of setting up ingress gateways, but its like a lego set: youll need to manually put the pieces together to have a production ready setup. Rewrites, redirects, or routes can easily be configured for various matching rules via custom resources, along with TLS termination, monitoring, tracing and a few other handy features. Along this config, theres also a label selector in the gateway that specifies which particular proxy (deployment) this configuration belongs to (see multiple gateways above). Backyards (now Cisco Service Mesh Manager) understands Istios Gateway resources and the gateways service configuration in Kubernetes, so it can display information about ports, hosts and protocols that are configured on a specific gateway. I'am on a journey of testing Istio and at the moment I'am about to test the "canary" capabilities of routing traffic. Tomorrow we will continue Thanks @saurabh3460 ! Find us at imprint.co.

My requirment is to create a outbond TCP/TLS connection to external server through any Egress gateway.And start sending Data to external server. 5) Configure Istio ingress for the Kubernetes dashboard. All the proxies and their associated policy checks add latency to your traffic. If these Gateway resources hold different port configs, or the same ports, but without overlapping hosts, these are merged by Istio. 2.1) Verify ifdashboard, andmetrics-serverare listed in the available add-ons for minikube. It makes Backyards (now Cisco Service Mesh Manager), Prometheus, and Grafana all available on localhost by proxying the internal Backyards ingress gateway that has some routing rules set for these particular services. Find out how you can get fine-grained control over pod version roll outs. layer over the underlying cluster management platform, such as Kubernetes. If you later find that more capabilities are required, explore them at a later time. Asking for help, clarification, or responding to other answers.
