SCOW在K8S集群上部署

1. 前提条件

• K8S集群已创建，若无可参考sealos快速安装k8s集群；
• 为K8S集群准备一个存储类，若无可参考K8S对接NFS共享存储；
• 已在K8S的一个master节点安装Helm，若无可参考官网安装；
• 部署SCOW的K8S集群节点挂载一个相同的共享目录，例如/scow。

2. 部署

2.1 给部署SCOW的节点打标签

# k8s-node01为规划中k8s中部署scow的节点，若有多个，请分别执行。
# app=scow 标签用于k8s的节点亲和性选择
kubectl label nodes k8s-node01 app=scow

2.2 SCOW部署节点设置

• 为部署scow的节点设置到登录节点的root免密(操作略)；

• 挂载共享目录，挂载点为/scow，并创建如下目录。

  # config用于存放scow部署配置
  # portal用于存放门户自定义入口数据
  # public用于存放自定义公共资源，如图片等
  mkdir /scow/{config,portal,public}

2.3 生成和配置部署文件

通过scow-cli生成配置文件：

# 下载
wget https://github.com/PKUHPC/SCOW/releases/download/latest/cli-x64

# 重命名
mv cli-x64 cli

#修改文件权限
chmod +x cli

#生成配置sample
./cli init

根据实际情况修改config目录中的配置文件(可不用配置install.yaml文件)，如何修改请参照SCOW文档网站，此处略。

配置完成后将config目录中的文件按照文件目录拷贝到/scow/config/。

2.4 开始部署

下载该项目，在安装了Helm的master节点执行：

git clone https://github.com/PKUHPC/scow-k8s.git

修改values.yaml配置文件，重点关注以下参数：

配置项	说明	备注
storageClass	为SCOW提供的存储类名称	根据实际存储类名称修改
image.repository	SCOW镜像仓库
image.tag	SCOW镜像tag	SCOW版本
gateway.nodePort	SCOW服务外部访问端口	k8s nodeport端口，大于30000，默认30080
gateway.resolver	k8s dns解析地址	默认kube-dns.kube-system.svc.cluster.local
***.db.db_password	***服务mysql数据库密码	默认为aWNvZGVAMjAyNA==，base64编码(icode@2024)

安装：

helm install scow . -n scow --create-namespace
