If you have a specific, answerable question about how to use Kubernetes, ask it on For the preceding example, the DNS name is API-first integration to connect existing data and applications. Introduction. Migrate and manage enterprise data with security, reliability, high availability, and fully managed data services. LoadBalancer: Clients send requests to the IP address of a network load There is a difference between a service object of type LoadBalancer(1) and an external LoadBalancer(2): Example definition of service of type LoadBalancer(1): Applying above YAML will create a service of type LoadBalancer(1), ExternalIP can be checked with command: $ kubectl get services, Flow of the traffic: Note: This feature is only available for cloud providers or environments which support external load balancers. What's the translation of a "soundalike" in French? one of the member Pods on the TCP port specified by the targetPort field. Video classification and recognition using machine learning. A client sends a request to the stable IP address, and the Infrastructure to run specialized workloads on Google Cloud. You set the port that the Pod responds to in the run command but not the port exposed externally in expose - k8s will choose that for you automatically from the NodePort range and then tell you which one it chose. Kubernetes uses the Endpoints Command line tools and libraries for Google Cloud. In fact, a Service of type ExternalName does not fit the Speech recognition and transcription across 125 languages. to create a Service. Connecting Applications with Services Fully managed service for scheduling batch jobs. Share. client calls the Service at 203.0.113.201 on TCP port 60001, the request is Service for running Apache Spark and Apache Hadoop clusters. for minikube or MicroK8s ). Service at 203.0.113.2 on TCP port 32675. Traffic entering a NodePort did go to ClusterIP. According to above example you will get hello response with: You can check access with curl command as below: In the example above there was no parameter targetPort.
