# 安装 kubespray

cd /opt
git clone https://github.com/kubernetes-sigs/kubespray.git
cd kubespray
pip3 install -r requirements.txt -i http://mirrors.aliyun.com/pypi/simple/ --trusted-host mirrors.aliyun.com

# 配置集群
# Copy ``inventory/sample`` as ``inventory/mycluster``
cp -rfp inventory/sample inventory/mycluster

# Update Ansible inventory file with inventory builder
declare -a IPS=(10.10.1.3 10.10.1.4 10.10.1.5)
CONFIG_FILE=inventory/mycluster/hosts.yaml python3 contrib/inventory_builder/inventory.py ${IPS[@]}

# 编辑 inventory/mycluster/hosts.yaml 文件

# 使用自定义配置
rm -rf /opt/kubespray/inventory/mycluster/group_vars
