is responsible for "backstage". Each resource generally has a controller, and controller manager is responsible for managing those controllers. For example, we create a pod through Apiserver, and when the pod is created, Apiserver's task is done. And the next guarantee that pod status is always the same as we expected the responsibility of the Controller manager to ensure. Etcd.

Notes on basic concepts of Kubernetes Kubernetes (K8s) is an open-source system for automatically deploying, scaling, and managing containerized applications. It is an "open-source version" of Google's internal tool Borg ". Kubernetes is currently recognized as the most advanced container cluster management tool. After
Analysis of Kubernetes Application Deployment model (Principles) Abstract: this series of articles focus on actual deployment and give you a quick grasp of Kubernetes. This article describes the principles and concepts that need to be understood before deployment, including the Kubernetes component structure, functions of each component role, and
ClusterCluster is a collection of compute, storage, and network resources, and Kubernetes uses these resources to run various container-based applicationsMasterMaster is the brain of cluster, whose primary responsibility is scheduling, that is, deciding where the application will run. Master runs the Linux operating system, which can be either a physical machine or a virtual machine. To achieve high availab

Docker enables more convenient management of single-machine container virtualization, where Docker is located between the operating system layer and the application layer; Relative traditional virtualization (Kvm,xen):Docker can be more flexible to implement some of the application layer functions, while the utilization of resources is also higher Relative application:Docker can better combine applications with more operating systems (mir

With such a large amount of data, there may be thousands of machines behind it, unable to manually monitor the state of the machine. Therefore, this article introduces the use of the Kubernetes container management tool and, through a simple example, tells you how to build a Spark cluster. Preparation Phase 1. You need to have a running kubernetes cluster and use

From Mesos to KubernetesThe previous scheduling framework was based on Mesos self-research. The language used is Python. Run for about two years, and has been relatively stable. But as the business grows, the problems of the existing framework are gradually exposed. Scheduling speed encountered bottlenecks, affecting the deployment of large business speed. There is no good support for stateful services. There are two solutions to this problem, one for improved refactoring of ex
