In this scenario, you'll learn how to use Kubectl to create and launch Deployments, Replication Controllers and expose them via Services without writing yaml definitions. This allows you to quickly launch containers onto the cluster. Step 1 - Launch…

六．部署kubectl客户端工具 1. 下载 [root@kubenode1 ~]# cd /usr/local/src/ [root@kubenode1 src]# wget https://storage.googleapis.com/kubernetes-release/release/v1.9.2/kubernetes-server-linux-amd64.tar.gz [root@kubenode1 src]# tar -zxvf kubernetes-server-linux-amd…

In this scenario, you'll learn how to use Kubectl to create and launch Deployments, Replication Controllers and expose them via Services by writing yaml definitions. YAML definitions define the Kubernetes Objects that become scheduled for deployment.…

这里记录kubernetes学习和使用过程中的内容. CentOS7 k8s-1.13 flanneld-0.10 docker-18.06 etcd-3.3 kubectl用法概述 kubectl是k8s客户端CLI工具,可以让用户通过命令行的方式对Kubernetes集群进行操作. kubectl命令行的语法如下: # kubectl [command] [TYPE] [NAME] [flags] kubectl命令行的参数和选项含义如下: command:子命令,用于操作k8s集群资源对象…

摘要:随着版本的不断迭代,k8s为了集群安全,集群中趋向采用TLS+RBAC的安全配置方式,所以我们在部署过程中,所有组件都需要证书,并启用RBAC认证. 我们这里采用二进制安装,下载解压后,把对应组件二进制文件copy到指定节点 master节点组件:kube-apiserver.etcd.kube-controller-manager.kube-scheduler.kubectl node节点组件:kubelet.kube-proxy.docker.coredns.calico 部署mast…

为了方便在命令行下对集群.节点.pod进行管理,kubernetes官方提供了一个管理命令:kubectl kubectl作为客户端CLI工具,可以让用户通过命令行对Kubernetes集群进行操作. 一.kubectl介绍 kubectl命令行的语法: kubectl [command] [TYPE] [NAME] [flags] command:子命令,用于操作Kubernetes集群资源对象的命令,例如create.delete.describe.get.apply等 TYPE:资源对象的…

安装kubectl 安装kubectl比较简单,几条命令即可(#后面为注释内容): #下载最新版本: curl -LO https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl #如果要下载特定版本,使用特定版本替换$(curl -s…

Share Process Namespace between Containers in a Pod how to configure process namespace sharing for a pod. When process namespace sharing is enabled, processes in a container are visible to all other containers in that pod. You can use this feature to…

Configure Service Accounts for Pods A service account provides an identity for processes that run in a Pod. This is a user introduction to Service Accounts. See also the Cluster Admin Guide to Service Accounts. When you (a human) access the cluster (…

概述: Kubernetes项目目前依然延续着之前爆炸式的扩张.急需能够理解Kubernetes原理并且贡献代码的软件开发者.学习Kubernetes源码并不容易.Kubernetes是使用相对年轻的Go语言编写,并且拥有大量的源代码.在这个系列的多篇文章里,我将为大家深入分析Kubernetes的关键源码,以及介绍那些帮助我理解源码的技术.我的目标是提供一系列的文章,让对于Kubernetes还较为陌生的开发者能够快速学习Kubernetes源码. 在第一篇文章里,我会分析从运行一个简单的ku…
