高可用安装

使用 ocboot 部署工具高可用安装 Cloudpods 服务，更符合生产环境的部署需求

环境准备

关于环境的准备和不同架构 CPU 操作系统的要求，请参考 All in One 安装/机器配置要求。

假设准备好了 3 台 CentOS7 机器，以及 1 台 Mariadb/MySQL 的机器，规划如下：

role	ip	interface	note
k8s primary	10.127.90.101	eth0	-
k8s master 1	10.127.90.102	eth0	-
k8s master 2	10.127.90.103	eth0	-
k8s VIP	10.127.190.10	-	-
DB	10.127.190.11	-	pswd=“0neC1oudDB#”, port=3306

其中 DB 的部署目前是不归 ocboot 部署工具管理的，需要提前手动部署，高可用的数据库部署可以参考文档部署 DB HA 环境。

开始安装

下载 ocboot

参考 All in One 安装/下载 ocboot。

编写部署配置

# 填充变量，生成配置
DB_IP="10.127.190.11"
DB_PORT=3306
DB_PSWD="0neC1oudDB#"
DB_USER=root

K8S_VIP=10.127.190.10
PRIMARY_INTERFACE="eth0"
PRIMARY_IP=10.127.90.101

MASTER_1_INTERFACE="eth0"
MASTER_1_IP=10.127.90.102
MASTER_2_INTERFACE="eth0"
MASTER_2_IP=10.127.90.103

cat > config-k8s-ha.yml <<EOF

  - user: root
    hostname: "$MASTER_2_IP"
    host_networks: "$MASTER_2_INTERFACE/br0/$MASTER_2_IP"
EOF

开始部署

$ ./ocboot.py install ./config-k8s-ha.yml

等待部署完成后，就可以使用浏览器访问 https://10.127.190.10 (VIP), 输入用户名 admin 和密码 admin@123，进入前端。

另外部署完成后，可以给已有集群添加节点，参考文档：添加计算节点。
