Service

Service defines the access method to access the back-end Pod. For details of the service, please see kubernets official documentation - Service. Two access methods are currently supported.

• Internal: that is, the Service’s ClusterIP mode, which automatically assigns the cluster internal IP address for internal cluster access only.
• External: I.e. Loadbalance mode of Service, used with the load balancing service provided by external OneCloud , accessing the back-end pod through the service address of the load balancing instance, suitable for Web class services.

Entry: In the cloud management platform, click the top left corner of navigation menu, and click “Containers/Service & Load Balancing/Service” menu item in the left menu bar that pops up to enter the services page.

1. In the service page, by default, you can view the service information of all namespaces under a cluster.

2. When there are multiple clusters in the environment, click the input box on the right side of the cluster above the list and select other clusters to view the service information of all namespaces under other clusters.

3. When there are multiple namespaces under the cluster, click the input box on the right side of the namespace above the list, select the namespace, and view the service information under the specified namespace.

   

Create service

This function is used to create services based on existing deployment and Statefulset applications.

2. Configure the following parameters.
   • Name: The name of the service.
   • Cluster: Select the cluster to which the service belongs.
   • Namespace: Select the namespace to which the service belongs. Namespaces are used to logically divide the cluster. deployment, pod, service, etc. all belong to a namespace. Kubernetes cluster will generate default, kube-system, and kube-public namespaces by default after the cluster is created.
   • Selector: corresponds to the spec.selector of the yaml file, which is used to select the created stateless or stateful applications.
   • Service: Set the access method for stateless or stateful applications and container groups, including internal access and external access.
     • Internal: A ClusterIP will be automatically generated for access within the cluster and between container groups.
       • Target port: The target port is the port on the pod.
       • Service port: The user access port.
       • Protocol: Select the protocol used by the application, including TCP and UDP.
     • External: will be used with the load balancing function for access outside the cluster. Before using external service, you need to create load balancing cluster and nodes in load balancing first. When creating external service, a load balancing instance will be created in load balancing synchronously.
       • Load balancing network: select IP subnet, the system will automatically assign an IP address from the IP subnet as the access IP.
       • Target port: The target port is the port on the pod.
       • Service port: The external user access port.
       • Protocol: Select the protocol used by the application, including TCP and UDP.
