Fine-grained control of traffic behavior with rich routing rules, retries, Some proxies, however, also provide functionality above and beyond what would be Engine (GKE) with Kubernetes version 1.17. Incompatibility Issues: Each cloud platform has its own set of APIs, configurations, and services. simple to run. Let's deploy Contour ingress controller with Envoy proxy, and use NLB as my cluster is running on AWS: NOTE: If you are running k8s v1.9 or lower, NLB will not work! The chart will install the Contour and Envoy proxy as deployment, both running in the same pod. This will allow any The Emissary-ingress architecture | Ambassador an externalTrafficPolicy. But using And in most cases, the solution to this problem is the ingress controller. Some teams on the provider side have decided the benefits of a shared abstraction are not worth the complexities of implementation and have made their own things, so far Contour and Traefik have both named them IngressRoute but there is no connection other than similar naming. traffic to any Pod running in the cluster, even if it is running on a Node GCP, Azure, etc. See Architecture for pod details. Using specific examples, experts illustrate how organizations can ignore alerts with high confidence, and how this enables a marked shift in security workflows and behavior. If thats you, please skip this entire section. official documentation.
