kubernetes 1.18.3 版本 二进制部署

kubernetes系列


一: 系统环境介绍
二: 部署Etcd集群
三: 安装docker
四: 部署k8s Master Node
五: 部署k8s Worker Node
六: 部署Dashboard和CoreDNS


一: 系统环境介绍

1.1 环境准备

  1. 在开始之前,部署Kubernetes集群机器需要满足以下几个条件:
  2. 操作系统: CentOS7.8-86_x64
  3. 硬件配置:2GB或更多RAM2CPU或更多CPU,硬盘30GB或更多集群中所有机器之间网络互通
  4. 可以访问外网,需要拉取镜像,如果服务器不能上网,需要提前下载镜像并导入节点
  5. 禁止swap分区

1.2 软件环境:

  1. 操作系统: CentOS7.8_x64 mini
  2. Docker: 19-ce
  3. Kubernetes: 1.18.3

1.3 环境规划

  1. 服务器整体规划:

1.4 单Master架构图:

1.5 单Master服务器规划:

image_1e9t7tee516e18pd1col92o1nok20.png-69.6kB

1.6 操作系统初始化配置

  1. # 关闭防火墙
  2. systemctl stop firewalld
  3. systemctl disable firewalld
  4. # 关闭selinux
  5. sed -i 's/enforcing/disabled/' /etc/selinux/config # 永久
  6. setenforce 0 # 临时
  7. # 关闭swap
  8. swapoff -a # 临时
  9. sed -ri 's/.*swap.*/#&/' /etc/fstab # 永久
  10. # 根据规划设置主机名
  11. hostnamectl set-hostname <hostname>
  12. # 在master添加hosts
  13. cat >> /etc/hosts << EOF
  14. 192.168.100.11 node01.flyfish
  15. 192.168.100.12 node02.flyfish
  16. 192.168.100.13 node03.flyfish
  17. EOF
  18. # 将桥接的IPv4流量传递到iptables的链
  19. cat > /etc/sysctl.d/k8s.conf << EOF
  20. net.bridge.bridge-nf-call-ip6tables = 1
  21. net.bridge.bridge-nf-call-iptables = 1
  22. EOF
  23. sysctl --system # 生效
  24. # 时间同步
  25. yum install chronyd
  26. server ntp1.aliyun.com

二、部署Etcd集群

2.1 ETCD 集群的概念

  1. Etcd 是一个分布式键值存储系统,Kubernetes使用Etcd进行数据存储,所以先准备一个Etcd数据库,为解决Etcd单点故障,应采用集群方式部署,这里使用3台组建集群,可容忍1台机器故障,当然,你也可以使用5台组建集群,可容忍2台机器故障

image_1eanr5rv217iet32g0n1sv62739.png-23.5kB

  1. 注:为了节省机器,这里与K8s节点机器复用。也可以独立于k8s集群之外部署,只要apiserver能连接到就行。

2.2准备cfssl证书生成工具

  1. cfssl是一个开源的证书管理工具,使用json文件生成证书,相比openssl更方便使用。
  2. 找任意一台服务器操作,这里用Master节点。
  3. ---
  4. wget https://pkg.cfssl.org/R1.2/cfssl_linux-amd64
  5. wget https://pkg.cfssl.org/R1.2/cfssljson_linux-amd64
  6. wget https://pkg.cfssl.org/R1.2/cfssl-certinfo_linux-amd64
  7. chmod +x cfssl_linux-amd64 cfssljson_linux-amd64 cfssl-certinfo_linux-amd64
  8. mv cfssl_linux-amd64 /usr/bin/cfssl
  9. mv cfssljson_linux-amd64 /usr/bin/cfssljson
  10. mv cfssl-certinfo_linux-amd64 /usr/bin/cfssl-certinfo
  11. ---

2.3 生成Etcd证书

  1. 1. 自签证书颁发机构(CA
  2. 创建工作目录:
  3. mkdir -p ~/TLS/{etcd,k8s}
  4. cd TLS/etcd

image_1e9t8qmhe1kfooa24101i411e2b37.png-138.9kB

  25. }
  26. ]
  27. }
  28. EOF
  29. 生成证书:
  30. cfssl gencert -ca=ca.pem -ca-key=ca-key.pem -config=ca-config.json -profile=www server-csr.json | cfssljson -bare server

  1. 3. 启用 TLS Bootstrapping 机制
  2. TLS BootstrapingMaster apiserver启用TLS认证后,Node节点kubeletkube-proxy要与kube-apiserver进行通信,必须使用CA签发的有效证书才可以,当Node节点很多时,这种客户端证书颁发需要大量工作,同样也会增加集群扩展复杂度。为了简化流程,Kubernetes引入了TLS bootstraping机制来自动颁发客户端证书,kubelet会以一个低权限用户自动向apiserver申请证书,kubelet的证书由apiserver动态签署。所以强烈建议在Node上使用这种方式,目前主要用于kubeletkube-proxy还是由我们统一颁发一个证书。
  3. TLS bootstraping 工作流程:

  2. $ wget https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.0-beta8/aio/deploy/recommended.yaml
  3. 默认Dashboard只能集群内部访问,修改ServiceNodePort类型,暴露到外部:
  4. vim recommended.yaml
  5. ----
  6. kind: Service
  7. apiVersion: v1
  8. metadata:
  9. labels:
