kubernetes blog

Haven't written a blog for a long time, the company engaged in a period of 997 is too brutal. 997 End also fast 1 weeks, finally slow down a bit, first two easy article, and then a little work, write a Kubernetes series. This article mainly introduces the kubernetes related commands, for the initial contact Kubernetes

Recently in the Docker and her management tools, the selection of kuberetes, by her terminology and concepts to get dizzy ... Read an article is not bad, put it here to share.Address: http://www.linuxidc.com/Linux/2015-12/125757.htmThe citations are as follows:As an important member of the Docker ecosystem, Kubernetes is an open source version of Google's many years of large-scale container management technology and is the best practice for line-of-pr

Apiserver is responsible for providing restful Kubernetes API service, it is the unified entrance of the System Management Directive, any operation that increases and deletions the resources should be handed over to apiserver processing and then submitted to ETCD. As shown in the architecture diagram, KUBECTL (t

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

In the previous blog post, we completed the Sonarqube deployment through Kubernetes's devlopment and service. Seems to be available, but there is still a big problem. We know that databases like MySQL need to keep data and not lose data. And the container is exactly the moment you exit, all data is lost. Once our Mysql-sonar container is restarted, any subsequent settings we make to Sonarqube will be lost. So we have to find a way to keep the MySQL da

First of all, to everyone popular science under the kubernetes choice of the network interface, a brief introduction of the network implementation of the background.The container network Interface is a set of container networks definition specification, including method specification, parameter specification, response specification and so on. The MLM only requires that network resources be freed when the container is created, when the container is all

Given the popularity of Docker, Google launched Kubernetes management docker cluster, and many people are expected to try. Kubernetes is supported by a large number of companies, and the Kubernetes Cluster deployment Tool integrates the IaaS platform such as Gce,coreos,aws, which is also very convenient to deploy. Given that many of the online materials are based

Once again, the architecture is clear: three virtual machine CentOS 7.4 systems, Docker 17, IP 10.10.90.105 to 107, 105-bit master, and the next master-related components installed on this machine.The ETCD cluster is 3 units, which are reused for each of the 3 virtual machines.As the core of k8s, the master node consists of three components, namely:Three components:kube-apiserverkube-schedulerkube-controller-managerThis three components are closely linked1.

stability. The format validation of Json-schema for CRD resources can refer to the document CRD validation proposal. Refer to document garbage collection for related resource recycling.Next, let's look at some CRDs limitations: CRD does not provide version conversion functionality, that is, there can be only one version per CRD (not expected to be seen in the near or medium term to support CRD version conversions). In Kubernetes1.7, there is no correlation check validation for CRD at pr

It periodically obtains pods assigned to the native from Etcd, and starts or stops the appropriate containers based on pod information. It also receives Apiserver HTTP requests to report the status of the pod.Pr

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 KUBECTL to configure access permissions for

Basic knowledgeFirst: Docker is an open-source container, in fact this technology is not new. In the early days of Linux, there was a lightweight virtualization system like LXC. Docker is actually just a language to implement. Kubernetes means the helmsman of sailing, it's a powerful orchestration + Monitor + disaster preparedness + load management system for DockerSecond: Kubernetes is a summary and best p

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 the release of
