You need to remove the following pod, but you cannot delete it using the following command: KUBECTL delete pod kong-rc-2364486572-3hgpk Looking at this instance's information, we found that the container was running on kubernetes node, but now that node is down. So now that node is down, it's time to just remove node. After node deletion, the pod inside the node is deleted. But if you don't want to delete this node, then start the node as follows: S

If you're an OPS engineer, you know that Docker is valued at more than $1 billion, and Docker is one of the most popular technology brands. Docker containers are known as the de facto standard for container runtimes, but Google's kubernetes is winning the choreography framework market. When using container technology, we often encounter the question, "will using Kubernetes hurt Docker?" ”Many people believe

Controller manager, as the Management control center within the cluster, is responsible for the resource management in the cluster, including node, Pod, namespace, and rated resources. For example, when an unexpected node outage occurs, Controller Manager will promptly discover and perform an automated fix.First, deploy k8s Controller ManagerMake sure Controller-manager-key.pem and Controller-manager.pem exist, and I've created the relevant private key here in the previous article.

The content of this article has been validated based on k8s v1.8.8. K8s Service defines the access entry address of a server, the front-end application accesses a cluster of pod replicas behind it through this entry address, and the access requests from outside are load balanced to each container application on the back end. Between the service and the back-end pod replica cluster, the docking is done through the label selector. The function of RC is to ensure service ability and service quality

Ubernetes is the King of container orchestration and scheduling, it beats the competitors Docker swarm and Apache Mesos, opens the bright future, microservices can be self-repairing, can be automatically expanded, can cross zone, Region even across cloud providers for federate. In this new era of cloud-native applications, it is becoming increasingly important to have a simple insight into how services interact with each other, which can be different from a haystack-wide search for a specific ca
