ansible一键部署k8s单机环境
来源：cnblogs　　作者：Chen_linux　　时间：2019/4/15 8:49:30　　对本文有异议

一、虚拟机准备

干净的Centsot7.4、4G内存、2个CPU

最小化安装，最好带虚拟化

 

二、执行初始化脚本

注意：脚本中配置静态网卡根据实际网卡名称配置，我用的是ens33

可以用 sed -i "s/ens33/（实际网卡名)/g" 文件路径 进行替换

  1. #!/bin/bash
  2. echo "正在执行安装k8s环境初始化..."
  3. #关闭防火墙
  4. /usr/bin/iptables -F >/dev/null 2>&1
  5. /usr/bin/iptables -X >/dev/null 2>&1
  6. /usr/bin/systemctl disable firewalld.service >/dev/null 2>&1
  7. /usr/bin/systemctl stop firewalld.service >/dev/null 2>&1
  8. echo "执行关闭防火墙..."
  10. #禁用SELINUX
  11. /usr/sbin/setenforce 0
  12. /usr/bin/sed -i 's/^SELINUX=enforcing$/SELINUX=disabled/' /etc/selinux/config
  13. echo "执行关闭selinux..."
  15. #关闭swap
  16. /usr/sbin/swapoff -a
  17. echo "vm.swappiness = 0">> /etc/sysctl.conf
  18. echo "执行关闭swap..."
  20. #配置静态网络
  21. echo "配置静态网络..."
  22. cat << EOF >/etc/sysconfig/network-scripts/ifcfg-ens33
  23. TYPE="Ethernet"
  24. BOOTPROTO="static"
  25. IPADDR="`ifconfig ens33 | grep broadcast | awk -F " " '{print $2}'`"
  26. NETMASK="`ifconfig ens33 | grep broadcast | awk -F " " '{print $4}'`"
  27. GATREWAY="`route -n | grep UG | awk -F " " '{print$2}'`"
  28. NAME="ens33"
  29. DEVICE="ens33"
  30. ONBOOT="yes"
  31. PEERDNS="yes"
  32. DNS1="114.114.114.114"
  33. DNS2="8.8.8.8"
  34. DNS3="`route -n | grep UG | awk -F " " '{print$2}'`"
  35. EOF
  37. cat <<EOF >/etc/sysconfig/network
  38. GATEWAY=`route -n | grep UG | awk -F " " '{print$2}'`
  39. EOF
  41. #配置yum源
  42. cat << EOF >/etc/yum.repos.d/163.repo
  43. [163]
  44. name=163
  45. baseurl=http://mirrors.163.com/centos/7/os/x86_64/
  46. gpgcheck=0
  47. enable=1
  48. EOF
  50. cat << EOF >/etc/yum.repos.d/epel.repo
  51. [epel]
  52. name=epel
  53. baseurl=https://mirrors.aliyun.com/epel/7/x86_64/
  54. enabled=1
  55. gpgcheck=0
  56. EOF
  57. echo "写入网络yum源..."
  59. #更新yum源
  60. yum clean all >/dev/null 2>&1
  61. yum makecache >/dev/null 2>&1
  62. echo "更新yum源..."
  64. #安装wget、ansible
  65. yum install -y wget >/dev/null 2>&1
  66. yum install -y ansible >/dev/null 2>&1
  67. echo "安装wget、ansible工具..."
  69. #定义ansible组
  70. cat << EOF >>/etc/ansible/hosts
  71. [k8s]
  72. `ifconfig ens33 | grep broadcast | awk -F " " '{print $2}'`
  73. EOF
  74. echo "配置ansible组..."
  76. #设置主机名
  77. echo -n "请输入主机名："
  78. read -p "" name
  79. /usr/bin/hostnamectl --static set-hostname $name
  80. if [ $? = 0 ]
  81. then
  82.    echo "修改主机名成功..."
  83. else
  84.    echo "修改主机名失败..."
  85.    exit
  86. fi
  87.  
  88. echo "初始化完成..."
  89. echo "正在执行重启操作..."
  90. sleep 3
  91. /usr/sbin/init 6

 

三、执行ssh进行主机验证

ssh root@本机ip

若不执行，ansible执行会报错

 

四、ansible部署k8s环境准备

注意：shell脚本我统一放在/root/start-sh/目录下

mkdir -p /root/start-sh/

cd /root/start-sh/

vim docker-k8s.sh

创建docker-k8s.sh脚本，其内容是拉取k8s镜像

  1. #!/bin/bash
  2. #下载镜像
  3. docker pull mirrorgooglecontainers/kube-apiserver:v1.14.0
  4. docker pull mirrorgooglecontainers/kube-controller-manager:v1.14.0
  5. docker pull mirrorgooglecontainers/kube-scheduler:v1.14.0
  6. docker pull mirrorgooglecontainers/kube-proxy:v1.14.0
  7. docker pull mirrorgooglecontainers/pause:3.1
  8. docker pull mirrorgooglecontainers/etcd:3.3.10
  9. docker pull coredns/coredns:1.3.1
  10. docker pull registry.cn-shenzhen.aliyuncs.com/cp_m/flannel:v0.10.0-amd64
  11. #给镜像打tag
  12. docker tag mirrorgooglecontainers/kube-apiserver:v1.14.0 k8s.gcr.io/kube-apiserver:v1.14.0
  13. docker tag mirrorgooglecontainers/kube-controller-manager:v1.14.0 k8s.gcr.io/kube-controller-manager:v1.14.0
  14. docker tag mirrorgooglecontainers/kube-scheduler:v1.14.0 k8s.gcr.io/kube-scheduler:v1.14.0
  15. docker tag mirrorgooglecontainers/kube-proxy:v1.14.0 k8s.gcr.io/kube-proxy:v1.14.0
  16. docker tag mirrorgooglecontainers/pause:3.1 k8s.gcr.io/pause:3.1
  17. docker tag mirrorgooglecontainers/etcd:3.3.10 k8s.gcr.io/etcd:3.3.10
  18. docker tag coredns/coredns:1.3.1 k8s.gcr.io/coredns:1.3.1
  19. docker tag registry.cn-shenzhen.aliyuncs.com/cp_m/flannel:v0.10.0-amd64 quay.io/coreos/flannel:v0.10.0-amd64
  20. #删除原镜像
  21. docker rmi mirrorgooglecontainers/kube-apiserver:v1.14.0           
  22. docker rmi mirrorgooglecontainers/kube-controller-manager:v1.14.0  
  23. docker rmi mirrorgooglecontainers/kube-scheduler:v1.14.0           
  24. docker rmi mirrorgooglecontainers/kube-proxy:v1.14.0               
  25. docker rmi mirrorgooglecontainers/pause:3.1                        
  26. docker rmi mirrorgooglecontainers/etcd:3.3.10                      
  27. docker rmi coredns/coredns:1.3.1
  28. docker rmi registry.cn-shenzhen.aliyuncs.com/cp_m/flannel:v0.10.0-amd64

创建k8s目录，编写kube-flannel.yaml文件（参照https://www.codesheep.cn/kube-flannel-yml/?spm=a2c4e.11153940.blogcont682810.11.6f853974iYJ4BU）

该内容目的是pod的网络通信

mkdir -p /root/kube-system/

cd /root/kube-system/

vim kube-flannel.yaml

yaml文件建好后使用一个脚本启动它

cd /root/start-sh/

vim start-pod-network

  1. #!/bin/bash
  2. #设置kubectl
  3. echo "export KUBECONFIG=/etc/kubernetes/admin.conf" >> /etc/profile
  4. source /etc/profile
  5. #安装pod network
  6. /usr/sbin/sysctl net.bridge.bridge-nf-call-iptables=1
  7. kubectl apply -f /root/k8s/kube-system/kube-flannel.yaml

准备好k8s需要的环境文件后编写ansible剧本

mkdir -p /root/asnible

cd /root/ansible

vim k8s.yml

注意：init k8s我使用了一个awk获取本地ip也是根据ens33网卡

  36.     shell: bash /root/start-sh/docker-k8s.sh

  38.     shell: swapoff -a
  39.   - name: init k8s
  40.     ignore_errors: yes
  41.     shell: kubeadm init --kubernetes-version=v1.14.0 --apiserver-advertise-address `ifconfig ens33 | grep broadcast | awk -F " " '{print $2}'`  --pod-network-cidr=10.244.0.0/16
  42.   - name: install pod network
  43.     script: /root/start-sh/start-pod-network.sh
  44.   - name: source kubcetl
  45.     shell: source /etc/profile

 

五、执行ansible一键部署

cd /root/ansible/

ansible-playbook k8s.yml --ask-pass

输入密码

开始执行中，过程会有些慢，因为需拉取镜像

 

六、验证pod是否正常

完成后执行 kubectl get pod -n kube-system查看pod状态

若输入命令无效，再执行一次source /etc/profile

k8s环境部署好了

技术不足望多见谅，若ansible有更好的优化方式可以留言交流

谢谢，祝工作顺利，身体健康
