Apiserver is the primary management node for the entire cluster, where the user configures and organizes the cluster through Apiserver, while the interactions between the nodes in the cluster and the ETCD store interact with the Apiserver. Apiserver implements a set of Restfull interfaces that allow users to interact directly wit

Kubernetes using NFS as a shared storageKubernetes managed containers are encapsulated, and sometimes we need to put logs from the container running locally or shared storage to prevent the container from going down, and the logs can also analyze the problem. Kubernetes's shared storage scheme is currently more prevalent in three, namely: Nfs,glusterfs and Ceph.Previously wrote an article kubernetes use Glu

kubernetes clinet-go Development (I.) Kubernetes currently provides two ways to create the required pod,service,replicationcontroller, one is through Kubectl create-f, a restful interface via HTTP, because of the work item's reason, Need to be customized according to the actual business needs of the development of K8s API, I used the library is the official, code base address: Https://github.com/

Service on the line to the top of the live pressure, carry the test, or to be said or we do things brother, remember this scene above? The old method is a service cluster deployment, but there is always a limit, before with Ali when they have a flexible calculation can be set by the CPU's threshold to dynamically expand and shrink computing capacity, at that time the feeling is very strong, at least at that time our conventional approach is difficult to do, Did not expect to have

kubernetes Introduction Kubernetes is a container cluster management system that Google Open-source in June 2014, using the Go language development, Kubernetes also called k8s. K8s is a Borg container cluster management system inside Google, Borg has been operating on Google's mass production for 10 years. K8s is mainly used for automated deployment, expansion

Rancher is an open-source full-stack enterprise container management platform, the user in the rancher visual interface in a single click to complete all the container infrastructure (network, storage, load balancing, etc.) docking and deployment, to ensure that the container on any infrastructure (public and private cloud, virtual machine, The physical machine, etc.) runs seamlessly. All the work of using containers in a production environment can be done with simple, intuitive operation.?start

In addition, OPS will want this OpenStack lifecycle management system to span bare metal, IaaS, and even PAAs.What Atomic, Docker, Kubernetes bringIf you have an OpenStack service lifecycle management scenario, the following benefits can be created: Isolated, lightweight, portable, detachable The service relationship of the running state is easy to describe Easy to run, easy to update Manage service life

Article from: Listen to the Cloud blogAs our business continues to grow, our number of applications has exploded. With the growth of application explosion, the difficulty of management is increased. How to quickly complete the expansion while the business explosion is growing is a big challenge. The advent of Docker happened to solve our problem. With Docker, we can quickly complete the expansion and contraction, and the configuration is uniform and error-prone.In the Docker cluster management s

Kubernetes about the service exposure is mainly through the Nodeport way, through the binding minion host of a port, then the pod request forwarding and load balancing, but this way the defect is The service may have many, if each is bound to a node host port, the host needs to open the perimeter of a heap of ports to make services calls, management confusion Cannot apply firewall rules required by many companies The ideal way is thr

OverviewKubernetes is a powerful container orchestration tool that enables users to reliably deploy and run containerized applications on a scalable system. Within the container area, k8s has undoubtedly become a community standard for container orchestration and management, and even Docker has announced support for K8s. The fighting in the field of container orchestration has been turned around, and the dust settles, and k8s has been unanimously endorsed by the players including Google, Huawei,
