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

What is the difference between Apache's Mesos and Google's kubernetes? This article comes from a question on the StackOverflow, mainly discusses the difference between Mesos and kubernetes, I believe many of us also have the question of agreeing. Kubernetes's developer Craig answered the question, while Masi also made an overview, not necessarily for the reader's reference.
Kubernetes is Google open source Docker container Cluster Management system, for the container of the application of resource scheduling, deployment operations, service discovery, expansion shrink capacity, such as a whole set of functions.
The composition of the entire k8s frame is shown below
The entire k8s architecture consists of two components: Master (APIs, Scheduler, replication Controller) and agents (Kubelet, proxy)
Explain the role of
Kubernetes is designed to solve the difficulties of managing a large-scale containerized environment. However, this does not mean that kubernetes can be extended in any environment. There are ways to maximize the scalability of kubernetes, and there are some important things and limitations to be aware of when extending kuber
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
Google Kubernetes Engine upgrade: regional cluster, new control panel, and security recommendations
Google has updated its Kubernetes Engine (GKE) service several times. You can now use GKE on a large scale. In addition to the kubectl command for cluster control and management, it also supports cluster management through the Cloud Console of a Web-side control panel. In addition, GKE can use Google best pra
The development track of modern cloud computing from the perspective of container and Kubernetes Technology
[Editor's note] This article is selected from the Google Cloud Platform Blog. It is the beginning of a series of blogs that mainly introduce container technology. This article briefly introduces container technology and kubernetes, describes the advantages of container technology and Google's understa
Mesos and Kuberneteshttp://dockone.io/article/956 I firmly believe that their use will grow faster in the next year, so it is time to review the summary and prepare for 2016 years. I would like to discuss the current situation of Mesos and kubernetes and enumerate the strengths and weaknesses that will allow you to understand the concept of cluster manager.Mesos and KubernetesBefore I start, I'd like to take the time to roughly compare Mesos and
Tags: WordPress MySQL KubernetesWordPress is the main platform for editing and publishing Web content. In this tutorial, I'll step through how to use kubernetes to build a high availability (HA) WordPress deployment.WordPress consists of two main components: a wordpress PHP server and a database for storing user information, posts, and website data. We need to make these two components in the entire application both highly available and fault tolerant
Run the MongoDB microservice on Docker and KubernetesGuideDocker is an open-source application container engine that allows developers to package their applications and dependencies to a portable container and then publish them to any popular Linux machine, you can also achieve virtualization. Containers fully use the sandbox mechanism and do not have any interfaces between them.

Watch the spark resource created on the cluster and how to operate it.We need to know before we start.What is KubernetesKubernetes (usually written as "k8s") is the first open source container cluster management project that was ultimately contributed by Google Design and development to Cloud Nat
1. Bash Auto-refill for KUBECTL commandsThis is probably the easiest thing to do in the kubernetes process, but it's also one of the most useful. To add the auto-refill feature, if you use bash, simply execute the following command:echo"sourceIt will add an auto-complete command to your. bashrc file. So each shell window you open supports this feature. I found that auto-completion is especially useful for some long parameters, such as--all-namespaces.

Docker Network BasicsSince Kubernetes is based on the Docker container as the carrier of the application release, the network characteristics of Docker also determine that kubernetes in building a container interoperability network must solve the problem of Docker's own network.Network namespacesTo support multiple instances of the network protocol stack, Linux introduces a network namespace in the network
