hosts.m-masters.example
配置如下

部署节点:运行这份 ansible 脚本的节点

[deploy]
192.168.0.30

etcd集群请提供如下NODE_NAME,注意etcd集群必须是1,3,5,7...奇数个节点

[etcd]
192.168.0.30 NODE_NAME=etcd1
192.168.0.31 NODE_NAME=etcd2
192.168.0.32 NODE_NAME=etcd3

[kube-master]
192.168.0.30
192.168.0.31

负载均衡有且仅有两个节点,安装 haproxy+keepalived

[lb]
192.168.0.30 LB_IF="ens192" LB_ROLE=backup # 注意根据实际使用网卡设置 LB_IF变量
192.168.0.31 LB_IF="ens192" LB_ROLE=master

[kube-node]
192.168.0.32
192.168.0.33

如果启用harbor,请配置后面harbor相关参数

[harbor]
#192.168.1.8

预留组,后续添加master节点使用

[new-master]
#192.168.1.5

预留组,后续添加node节点使用

[new-node]
#192.168.1.xx

[all:vars]

---------集群主要参数---------------

#集群部署模式:allinone, single-master, multi-master
DEPLOY_MODE=multi-master

#集群主版本号,目前支持: v1.8, v1.9, v1.10,v1.11
K8S_VER="v1.11"

集群 MASTER IP即 LB节点VIP地址,为区别与默认apiserver端口,设置VIP监听的服务端口8443

公有云上请使用云负载均衡内网地址和监听端口

MASTER_IP="192.168.0.35"
KUBE_APISERVER="https://{{ MASTER_IP }}:8443"

#TLS Bootstrapping 使用的 Token,使用 head -c 16 /dev/urandom | od -An -t x | tr -d ' ' 生成
BOOTSTRAP_TOKEN="c30302226d4b810e08731702d3890f50"

集群网络插件,目前支持calico, flannel, kube-router, cilium

CLUSTER_NETWORK="flannel"

服务网段 (Service CIDR),注意不要与内网已有网段冲突

SERVICE_CIDR="10.68.0.0/16"

POD 网段 (Cluster CIDR),注意不要与内网已有网段冲突

CLUSTER_CIDR="172.20.0.0/16"

服务端口范围 (NodePort Range)

NODE_PORT_RANGE="20000-40000"

kubernetes 服务 IP (预分配,一般是 SERVICE_CIDR 中第一个IP)

CLUSTER_KUBERNETES_SVC_IP="10.68.0.1"

集群 DNS 服务 IP (从 SERVICE_CIDR 中预分配)

CLUSTER_DNS_SVC_IP="10.68.0.2"

集群 DNS 域名

CLUSTER_DNS_DOMAIN="cluster.local."

etcd 集群间通信的IP和端口, 根据etcd组成员自动生成

TMP_NODES="{% for h in groups['etcd'] %}{{ hostvars[h]['NODE_NAME'] }}=https://{{ h }}:2380,{% endfor %}"
ETCD_NODES="{{ TMP_NODES.rstrip(',') }}"

etcd 集群服务地址列表, 根据etcd组成员自动生成

TMP_ENDPOINTS="{% for h in groups['etcd'] %}https://{{ h }}:2379,{% endfor %}"
ETCD_ENDPOINTS="{{ TMP_ENDPOINTS.rstrip(',') }}"

集群basic auth 使用的用户名和密码

BASIC_AUTH_USER="admin"
BASIC_AUTH_PASS="test1234"

---------附加参数--------------------

#默认二进制文件目录
bin_dir="/opt/kube/bin"

#证书目录
ca_dir="/etc/kubernetes/ssl"

#部署目录,即 ansible 工作目录,建议不要修改
base_dir="/etc/ansible"

#私有仓库 harbor服务器 (域名或者IP)
#HARBOR_IP="192.168.1.8"
#HARBOR_DOMAIN="harbor.yourdomain.com"
