介绍

安全方面

yapi容器使用非root权限
mongodb使用非root账号

首先我们创建一个dockerfile

FROM node:11-alpine as builder
WORKDIR /home/node
RUN wget https://github.com/YMFE/yapi/archive/refs/tags/v1.9.2.tar.gz
RUN tar -zxvf v1.9.2.tar.gz
RUN mv yapi-1.9.2 vendors
WORKDIR /home/node/vendors
RUN apk add python make
RUN npm install --production --registry https://registry.npm.taobao.org

FROM node:11-alpine
LABEL maintainer="xiesj@live.com"
WORKDIR /home/node/vendors
COPY --from=builder /home/node/vendors /home/node/vendors
USER node
ENV TZ="Asia/Shanghai"
EXPOSE 3000
CMD ["node","server/app.js"]

我们使用node11-alpine，需要额外安装python和make
这里使用了多重镜像，使用 copy --from 命令，第一个镜像作为builder镜像，把第一个镜像的builder结果，复制到第二个镜像里

制作成镜像

docker build -t xieshujian/yapi:1.9.2 .

镜像大小大概是164m，还是很小的

为了安全我们使用非root账号，为了安全我们不新建账号，直接使用node账号

apiVersion: v1
kind: Service
metadata:
  name: yapi
spec:
  selector:
    app: yapi
  ports:
    - protocol: TCP
      port: 80
      targetPort: 3000

我们把config.json这个文件制作成k8s secret文件，这里是用了base64,原始文件如下

{
  "port": "3000",
  "adminAccount": "admin@admin.com",
  "timeout":120000,
  "db": {
    "servername": "mongodb",
    "DATABASE": "yapidb",
    "port": 27017,
    "user": "yapiuser",
    "pass": "yapipassword",
    "authSource": "yapidb"
  },
  "mail": {
    "enable": false,
    "host": "smtp.163.com",
    "port": 465,
    "from": "***@163.com",
    "auth": {
      "user": "***@163.com",
      "pass": "*****"
    }
  }
}

我们会用mongodb，servername就是service name就叫mongodb
这里采用文件挂载，使用subPath，注意path要写到config.json,因为/yapi是非空目录，不是挂载整个目录，是挂载单个文件，坑1

探针，这里使用http探针，5秒跑一次

建立service叫yapi

创建命名空间

kubectl create ns yapi

安装mongodb

把mongodb chart下载解压，找到values.yaml,打开，修改里面的rootPassword的值改为taihu123
另外把useStatefulSet设置成true，我们使用statefull
执行下面命令安装mongodb
helm repo add bitnami https://charts.bitnami.com/bitnami
helm install mongodb bitnami/mongodb -n yapi -f values.yaml
安装完毕之后进入容器，执行下面命令，新建普通账号，和数据库

mongo -u root -p taihu123
use yapidb
db.createUser({user: "yapiuser",pwd: "yapipassword",roles: [ { role: "dbOwner", db: "yapidb" } ]} )

安装yapi

kubectl apply -f yapi yapi.yaml -n yapi
安装完毕之后，进入其中一个pod
执行下面命令
npm run install-server
初始化数据库
接下来就可以登录yapi了，账号是admin@admin.com,密码是ymfe.org
