1、下载kubespray

wget https://github.com/kubernetes-sigs/kubespray/archive/v2.13.3.tar.gz
mv v2.13.3.tar.gz kubespray_v2.13.3.tar.gz
tar zxvf kubespray_v2.13.3.tar.gz

2、安装pip3

yum install epel-release python36 python36-pip -y

3、安装依赖

cd kubespray-2.13.3/
pip3.6 install -r requirements.txt

4、更新配置

cp -rfp inventory/sample inventory/mycluster
declare -a IPS=(172.17.185.91 172.17.185.92 172.17.185.93 172.17.185.94)
CONFIG_FILE=inventory/mycluster/hosts.yaml python3.6 contrib/inventory_builder/inventory.py ${IPS[@]}

5、配置机器免登录

使用autossh.tar.gz 工具进行SSH免密配置.
注意:vim /etc/ssh/sshd_config里StrictModes no

6、验证免密

ansible all -i inventory/mycluster/hosts.yaml -m ping

7、替换官方镜像地址

修改文件：roles/download/defaults/main.yml

注意：由于使用https://storage.googleapis.com地址会被墙。

错误如下：(目前尚未解决)

TASK [download : download_file | Download item] ************************************************************************************************************************************************************
fatal: [node1 -> 172.17.185.91]: FAILED! => {"attempts": 4, "changed": false, "dest": "/tmp/releases/kubeadm-v1.17.9-amd64", "elapsed": 30, "msg": "Request failed: <urlopen error timed out>", "url": "https://storage.googleapis.com/kubernetes-release/release/v1.17.9/bin/linux/amd64/kubeadm"}

8、执行安装

ansible-playbook -i inventory/mycluster/hosts.yaml  --become --become-user=root cluster.yml
