[egg]: https://eggjs.org ### FINISH ## 构建项目关键点 egg-swagger-doc ```bash npm install --save egg-swagger-doc ``` 配置 开启服务，然后访问http://127.0.0.1:7001/swagger-ui.html TODO:编写注释。但不知为什么错了 > @Response 200 body 正确响应 ## TODO - 错误拦截 ## docker的dockerfile构建 ### es @eggplugin/es是三年前的插件，依赖的es版本已经不存在，会出各种问题，es^8.x版本放弃了type，search方法传的query没有body，所以还是自己写一个插件。 ```bash npm i @eggplugin/es --save ``` ### 自己写一个egg-es-client插件 问题：依赖的@elastic/elasticsearch需要在最外层安装，使用的8.4版本 ### docker构建 由于容器中的es，mongo都要配置，如果启动容器再配置很繁琐，用dockerfile配置的话比较简单。 #### ES容器 配置了es的dockerfile。 参照官网构建镜像运行容器 ```bash docker build -t es -f es.Dockerfile . # docker run -p 9200:9200 -d --name es es:8.4.1 docker run -d --name es --net somenetwork -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" elasticsearch:8.3.1 ``` 拷贝配置文件修改再拷贝回容器 ```bash docker cp ./elasticsearch1.yml es:/usr/share/elasticsearch/config/elasticsearch.yml docker cp es:/usr/share/elasticsearch/config/elasticsearch.yml ./elasticsearch1.yml # 配置密码，用于项目连接 docker exec -it es bash /bin$ elasticsearch-reset-password -u elastic -i ``` #### mongo容器 ```bash docker build -f mongo.Dockerfile -t mongo . docker run -d --name mongo -p 27017:27017 --network somenetwork mongo ``` #### 项目容器 构建项目镜像 ```bash docker build -f Dockerfile -t egg . # docker run -d --name egg_test -p 8080:7001 egg_test # docker run -d --name egg_test -P egg_test docker run -d --name egg -P --network somenetwork egg ``` 项目内需要连接其他容器的网络，所以设置network，这样容器间才能通信。 ```bash docker network create somenetwork docker network connect somenetwork egg docker network connect somenetwork mongo docker network connect somenetwork es docker restart egg ``` 注意踩坑 Dockerfile中这样写是错的。 CMD [npm","run","start"] 当各种容器启动了却发现容器间无法通信。 所以加了network实现容器间通信，也可以通过宿主机连接 连接mongo错误导致项目启动不了 [MONGODB DRIVER] Warning: Current Server Discovery and Monitoring engine is deprecated, and will be removed in a future version. To use the new Server Discover and Monitoring engine, pass option { useUnifiedTopology: true } to the MongoClient constructor. 所以配置改为这样 ```js config.mongoose = { url: 'mongodb://localhost:27017/test', options: { // user: 'admin', // 数据库用户名 // pass: '123456', // 数据库密码 // dbName: 'test' // 数据库名 useUnifiedTopology: true } } ``` 连接es失败，但有返回。 用window上的项目连接能，但容器中连接就失败，mongo也能连，就es不能。 应该网络连不上，网络不通。 容器间通信要了解下,可以用容器名连接，也可以用宿主机ip连接 ```bash > interface@1.0.0 start > egg-scripts start --daemon --title=egg-server-interface [egg-scripts] Starting egg application at E:\me\workplace\Nodejs\egg\interface_test [egg-scripts] Run node --no-deprecation --trace-warnings E:\me\workplace\Nodejs\egg\interface_test\node_modules\egg-scripts\lib\start-cluster {"title":"egg-server-interface","baseDir":"E:\\me\\workplace\\Nodejs\\egg\\interface_test","framework":"E:\\me\\workplace\\Nodejs\\egg\\interface_test\\node_modules\\egg"} --title=egg-server-interface [egg-scripts] Save log file to C:\Users\pgd\logs [egg-scripts] Wait Start: 1...
