information about the cluster, and even make changes to the cluster. In this case, Kubernetes provides a special authentication method: Service account. Service account, like pod, service, and deployment, is a resource in a kubernetes cluster, and users can create their own.ServiceAccount contains three main content: namespace, Token, and CA.

resources through selectors. For example, deployment and services.When you start writing a kubernetes configuration file, you feel good and think that maintenance is not a big problem. However, when you try to implement a deployment pipeline, you will find that using a bunch of configuration files is a very bad idea. At this point helm can save, Helm is a tool for packaging kubernetes applications, and I h

IP address and port, but access s Ervice this virtual IP and port, the service forwards the request to the pod behind it.Kubernetes, when creating a service, finds the pod based on the service's label selector (label Selector), creating a endpoints object with the same name as the service. When the address of the pod changes, the endpoints changes as well. When the service accepts the request, it can find the destination address of the request forwarding through endpoints.For example, the autho

Kubernetes has the concept of a namespace. Namespaces are a way of dividing cluster resources across multiple users (through resource quotas

. Main concepts of Kubernetes 2.1 Pods In the Kubernetes system, the smallest granularity of scheduling is not simply a container, but a Pod. A Pod is the smallest deployment unit that can be created, destroyed, scheduled, and managed. One or more containers (Container) constitute a Pod. Generally, the containers in the Pod run the same application. Pods contain containers running on the same Minion (Host)

Server saves the Node status information to ETCd. The Node Controller in Controller Manager regularly reads the status information of these nodes through the API Server and processes them accordingly. After listening to the information created by a Pod, Scheduler retrieves the list of all nodes that meet the Pod requirements and binds the Pod to the most compliant nodes in the node list: if schedpod detects that a Pod is deleted, the corresponding Pod instance on the current node is deleted.

Name space What is a namespace? The namespace (English: Namespace) represents the visible range of identifiers (identifier). An identifier can be defined in more than one namespace, and its meaning in different namespaces is mutually irrelevant. In this way, any identifiers can be defined in a new

Deployment model, including Pod, Replication controller, Label, and Service. Pod The minimum deployment unit of Kubernetes is Pod rather than container. As a First class API citizen, Pods can be created, scheduled, and managed. Simply put, like the peas in a Pod, the application containers in a Pod share the same context: PID namespace. But not in docker Network
