使用链接的泊坞窗容器configurationPM2模块

我有我的应用程序在Docker容器中

FROM keymetrics/pm2-docker-alpine:7 ENV environment development # Add PM2 modules RUN pm2 install pm2-mongodb ADD . . EXPOSE 3000 CMD ["pm2-docker", "ecosystem.config.js", "--env ${environment}"] 

我使用PM2和ecos.config.js

 module.exports = { apps: [ { name: 'api', script: 'api/index.js', env: { PORT: process.env.PORT || 3000, API_MONGO_URL: process.env.MONGO_URL || 'mongodb://localhost/api', }, env_production: { MONGO_URL: `mongodb://${process.env.MONGODB_PORT_27017_TCP_ADDR}:${process.env.MONGODB_PORT_27017_TCP_PORT}/api`, }, }, ], }; 

这个应用程序依赖于MongoDB服务…所以我运行这个链接的容器..

 docker run -it --name api -e environment=production --link mongodb:mongodb api:latest sh 

问题是当我在容器中执行这个命令…

 /app # pm2-docker ecosystem.config.js --env $environment [STREAMING] Now streaming realtime logs for [all] processes 0|pm2-mong | You have triggered an unhandledRejection, you may have forgotten to catch a Promise rejection: 0|pm2-mong | Error: double colon in host identifier 0|pm2-mong | at module.exports (/root/.pm2/node_modules/mongodb/lib/url_parser.js:89:13) 0|pm2-mong | at connect (/root/.pm2/node_modules/mongodb/lib/mongo_client.js:480:16) 0|pm2-mong | at /root/.pm2/node_modules/mongodb/lib/mongo_client.js:234:7 0|pm2-mong | at Function.MongoClient.connect (/root/.pm2/node_modules/mongodb/lib/mongo_client.js:230:12) 0|pm2-mong | at Object.init (/root/.pm2/node_modules/pm2-mongodb/lib/stats/client.js:53:15) 0|pm2-mong | at Object.init (/root/.pm2/node_modules/pm2-mongodb/lib/stats/index.js:78:12) 0|pm2-mong | at /root/.pm2/node_modules/pm2-mongodb/app.js:33:9 0|pm2-mong | at Object.PMX.initModule (/root/.pm2/node_modules/pmx/lib/pmx.js:116:12) 0|pm2-mong | at Object.<anonymous> (/root/.pm2/node_modules/pm2-mongodb/app.js:4:5) 0|pm2-mong | at Module._compile (module.js:571:32) PM2 | App [pm2-mongodb] with id [0] and pid [21], exited with code [0] via signal [SIGINT] PM2 | Starting execution sequence in -fork mode- for app name:pm2-mongodb id:0 PM2 | App name:pm2-mongodb id:0 online 

这个错误是因为我使用pm2-mongodb模块 ，我需要configuration模块如下…

 pm2 set pm2-mongodb:ip ${MONGODB_PORT_27017_TCP_ADDR} pm2 set pm2-mongodb:port ${MONGODB_PORT_27017_TCP_PORT} 

所以问题是… 何时/何地我可以做到这一点？

在我run容器后， MONGODB_PORT_27017_TCP_ADDR和MONGODB_PORT_27017_TCP_PORT将可用。
