使用 kubeadm 安装最新 Kubernetes 1.15 版本

荒凉一梦 提交于 2021-02-17 07:40:20
导读: kubeadm是Kubernetes官方提供的用于快速安装Kubernetes集群的工具,伴随Kubernetes每个版本的发布都会同步更新,kubeadm会对集群配置方面的一些实践做调整,通过实验kubeadm可以学习到Kubernetes官方在集群配置上一些新的最佳实践。 作者:青蛙小白 原文: https://blog.frognew.com/2019/07/kubeadm-install-kubernetes-1.15.html 最近发布的Kubernetes 1.15中,kubeadm对HA集群的配置已经达到beta可用,说明kubeadm距离生产环境中可用的距离越来越近了。 1.准备 1.1系统配置 在安装之前,需要先做如下准备。两台CentOS 7.6主机如下: cat /etc/hosts 192.168.99.11 node1 192.168.99.12 node2 如果各个主机启用了防火墙,需要开放Kubernetes各个组件所需要的端口,可以查看Installing kubeadm中的”Check required ports”一节。这里简单起见在各节点禁用防火墙: systemctl stop firewalld systemctl disable firewalld 禁用SELINUX: setenforce 0 vi /etc/selinux
