Ingress “Ingress exposes HTTP and HTTPS routes from outside the cluster to services within the cluster. If it does not, the load balancer marks the instance as unhealthy and does not send it any traffic until the health check shows that it is healthy again. In this two-part post, we will explore the set of observability tools which are part of the Istio Service Mesh. There is one final step we need to take to get this to work, that is because of an existing github issue with ingress-gce. Accelerating the transition to Containers by building a Kubernetes-native Cloud. Open the GKE page and create Kubernetes cluster. The GCE Ingress currently configures its health check to hit / (and defaults host header to the IP address) on the Istio gateway's HTTPS service port, but this will fail because Istio routes by the host name and a random IP address has no route. Daemonset is a pod that runs on every K8 host; The FluentD agent monitors logs that are generated from every K8 pod running on the host and streams the logs to Elastic Search Cluster. The Ingress controller looks for a compatible readiness probe first, if it finds one, it adopts it as the GCE loadbalancer's HTTP(S) health check. In the spec.
