Kubespray 是 Kubernetes incubator 中的项目，目标是提供 Production Ready Kubernetes 部署方案，该项目基础是通过 Ansible Playbook 来定义系统与 Kubernetes 集群部署的任务。

1、安装基础环境

yum install -y python-pip git sshpass
2、拉取官方代码

kubespray官方github地址

git clone https://github.com/kubernetes-sigs/kubespray

cd kubespray && sudo pip install -r requirements.txt
cp -rfp inventory/sample inventory/mycluster
3、修改镜像源为阿里源

vim inventory/mycluster/group_vars/k8s-cluster/k8s-cluster.yml
kube_image_repo: "registry.aliyuncs.com/google_containers"
4、修改基础镜像

vim roles/download/defaults/main.yml
kube_image_repo: "registry.aliyuncs.com/google_containers" --修改了上面的文件可不用修改此处
pod_infra_image_repo: "registry.aliyuncs.com/google_containers/pause-{{ image_arch }}" --pause-adm64:3.1
dashboard_image_repo: "registry.aliyuncs.com/google_containers/kubernetes-dashboard-{{ image_arch }}"

如果需要修改网络插件，可以修改下面的参数 (cilium, calico, contiv, weave or flannel)
kube_network_plugin: calico
5、搭建

ansible-playbook -i inventory/mycluster/hosts.ini --become --become-user=root cluster.yml
6、重置

ansible-playbook -i inventory/mycluster/hosts.ini --become --become-user=root reset.yml
7、修改集群基础配置

vim inventory/mycluster/group_vars/k8s-cluster/k8s-cluster.yml
kube_proxy_mode: ipvs --proxy_mode：ipvs，iptables
kube_network_plugin: flannel --network_plugin：cilium, calico, contiv, weave or flannel
dns_mode: coredns --dns: dnsmasq_kubedns, kubedns, coredns, coredns_dual, manual or none
8、启用ingress-nginx插件

vim inventory/mycluster/group_vars/k8s-cluster/addons.yml
ingress_nginx_enabled: false --开启nginx-ingress-controller 插件
