介绍

yapi是api 文档管理系统，基于nodejs和mongodb。集成ldap。
启用插件。本次启用的插件是把文档导出为word

编写entrypoint,sh

因为config.json这个配置，通过环境变量来配置比较方便，所以我们写一个entrypoint.sh文件，主要使用sed方法，用环境变量来替换json字段。具体如下，另外再加一个启动yapi的语句。
需要注意的是数字和布尔变量的sed语句和字符串sed语句有一点点不一样，需要多替换2个双引号。

#!/bin/sh
#update config file with env var
conf_file=/yapi/config.json
if [ $YAPI_SERVER_PORT ]; then
    sed -i "s#\"YAPI_SERVER_PORT\"#$YAPI_SERVER_PORT#" $conf_file
fi
if [ $YAPI_ADMINACCOUNT ]; then
    sed -i "s#YAPI_ADMINACCOUNT#$YAPI_ADMINACCOUNT#" $conf_file
fi
if [ $YAPI_TIMEOUT ]; then
    sed -i "s#\"YAPI_TIMEOUT\"#$YAPI_TIMEOUT#" $conf_file
fi
#mongodb
if [ $YAPI_DB_SERVERNAME ]; then
    sed -i "s#YAPI_DB_SERVERNAME#$YAPI_DB_SERVERNAME#" $conf_file
fi
if [ $YAPI_DB_DATABASE ]; then
    sed -i "s#YAPI_DB_DATABASE#$YAPI_DB_DATABASE#" $conf_file
fi
if [ $YAPI_DB_PORT ]; then
    sed -i "s#\"YAPI_DB_PORT\"#$YAPI_DB_PORT#" $conf_file
fi
if [ $YAPI_DB_USER ]; then
    sed -i "s#YAPI_DB_USER#$YAPI_DB_USER#" $conf_file
fi
if [ $YAPI_DB_PASS ]; then
    sed -i "s#YAPI_DB_PASS#$YAPI_DB_PASS#" $conf_file
fi
if [ $YAPI_DB_AUTHSOURCE ]; then
    sed -i "s#YAPI_DB_AUTHSOURCE#$YAPI_DB_AUTHSOURCE#" $conf_file
fi

#start yapi
node server/app.js

编写yapi的dockerfile

基础镜像是node:11.15
最后打包镜像是node:11.15-alpine
把entrypoint.sh从本人github下载下来，加入到镜像中。
把config.json也从本人github下载下来，放入镜像中。
还需要下载input.docx

FROM node:11.15 as builder
WORKDIR /yapi
RUN npm install -g node-gyp yapi-cli ykit
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
RUN wget https://raw.githubusercontent.com/xie-shujian/yapi/main/ldap_docx/config.json
RUN yapi plugin --name yapi-plugin-export-docx-data
WORKDIR /yapi/vendors
RUN npm install --production
RUN wget https://raw.githubusercontent.com/xie-shujian/yapi/main/ldap_docx/entrypoint.sh
RUN wget https://raw.githubusercontent.com/inceptiongt/Yapi-plugin-export-docx-data/master/input.docx

FROM node:11.15-alpine
LABEL maintainer="xiesj@live.com"
ENV TZ="Asia/Shanghai"
COPY --from=builder /yapi/vendors /yapi/vendors
COPY --from=builder /yapi/config.json /yapi/config.json
WORKDIR /yapi/vendors
RUN cat /yapi/config.json
EXPOSE 3000
ENTRYPOINT ["sh", "entrypoint.sh"]

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-ldap .

镜像大小大概是164m，还是很小的

k8s部署yaml文件

• 创建secret
• 创建部署
  编写环境变量，包含mongodb的连接信息
  编写探针
• 创建service
  service端口是80，容器端口是3000

config.json是修改过的

因为word插件会修改这个配置文件，所以这个json必须是合法的

{
  "port": "YAPI_SERVER_PORT",
  "adminAccount": "YAPI_ADMINACCOUNT",
  "timeout": "YAPI_TIMEOUT",
  "db": {
    "servername": "YAPI_DB_SERVERNAME",
    "DATABASE": "YAPI_DB_DATABASE",
    "port": "YAPI_DB_PORT",
    "user": "YAPI_DB_USER",
    "pass": "YAPI_DB_PASS",
    "authSource": "YAPI_DB_AUTHSOURCE"
  },
  "mail": {
    "enable": "YAPI_MAIL_ENABLE",
    "host": "YAPI_MAIL_HOST",
    "port": "YAPI_MAIL_PORT",
    "from": "YAPI_MAIL_FROM",
    "auth": {
      "user": "YAPI_MAIL_USER",
      "pass": "YAPI_MAIL_PASS"
    }
  },
  "ldapLogin": {
    "enable": "YAPI_LDAP_ENABLE",
    "server": "YAPI_LDAP_SERVER",
    "baseDn": "YAPI_LDAP_BASEDN",
    "bindPassword": "YAPI_LDAP_BINDPASSWORD",
    "searchDn": "YAPI_LDAP_SEARCHDN",
    "searchStandard": "YAPI_LDAP_SEARCHSTANDARD",
    "emailPostfix": "YAPI_LDAP_EMAILPOSTFIX",
    "emailKey": "YAPI_LDAP_EMAILKEY",
    "usernameKey": "YAPI_LDAP_USERNAMEKEY"
 }
}

我们会用mongodb，servername就是service name就叫mongodb

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.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
