ansible部署k8s详解

服务器IP分配：
master1 192.168.50.171
master2 192.168.50.190
node1 192.168.50.191
node2 192.168.50.192
etcd1 192.168.50.193
etcd2 192.168.50.194
etcd3 192.168.50.195
harbor 192.168.50.196
keepalived+haproxy 192.168.50.197 vip 192.168.50.201
keepalived+haproxy 192.168.50.198

所有的服务器的时间尽量要一致seliux关闭（不一致可能会影响证书的签发）

harbor服务器：
harbor按照顺序执行，否则可能出错)

yum install python-pip -y
装docker-ce (yum 装即可)
包 harbor （将harbor的包解压到该目录 /usr/local/src/）
进入/usr/local/src/harbor
pip install docker-compose
修改配置文件
hostname = 192.168.50.196 （本机ip）
harbor_admin_password = 123456 （登录harbor的密码，账号为admin）
启动docker
./install.sh

keepalived+haproxy服务器：

haproxy+keepalived
装包 修改配置文件 （下方的操作 否则haproxy不能启动到两台机器里）
修改配置文件 （keepalived）

[root@k8s-ha1 keepalived-1.4.2]# cat /etc/keepalived/keepalived.conf
vrrp_instance VI_1 {
    state MASTER  （另一个改为BACKUP）
    interface eth0
    virtual_router_id 1
    priority 100
    advert_int 3
    unicast_src_ip 192.168.50.197
    unicast_peer {
        192.168.50.198
    }

    authentication {
        auth_type PASS
        auth_pass 123abc
    }
    virtual_ipaddress {
        192.168.50.201 dev eth0 label eth0:1
    }
}

haproxy的配置文件：

global

#chroot /usr/local/haproxy
#stats socket /var/lib/haproxy/haproxy.sock mode 600 level admin
