node as a working node in a cluster, running a real application, the smallest unit of Kubernetes managed on node is pod. Node runs kubernetes kubelet, Kube-proxy service processes that are responsible for pod creation, start-up, monitoring, restart, destruction, and load balancing of software patterns.
Node contains information: node address: The IP address of the host, or
What is the difference between Apache's Mesos and Google's kubernetes?

As soon as I arrived this morning, I received a "complaint" from my colleague: a node in the Kubernetes cluster on the private cloud seemed to be out of work because the application that was specifically deployed on that node was hung up and was not recovered for a long time. This company private cloud Kubernetes cluster is th
Kubernetes (hereinafter referred to as "k8s") is now recognized as the most advanced container cluster management tool, after the release of the 1.0 release, the development of k8s more rapidly, and has been the full support of the container ecosystem manufacturers, including coreos, rancher, etc., Many vendors that provide public cloud services also provide container services based on k8s for two development to support the infrastructure layer, such
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
