Mongodb 使用链接的docker容器配置PM2模块

我的应用程序位于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}"]

我将PM2与ecosystem.config.js一起使用

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`,
      },
    },
  ],
};

此应用程序依赖于MongoDB服务。。。所以我用链接容器运行这个

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

问题是当我在容器内执行此命令时

/app # pm2-docker ecosystem.config.js --env $environment

PM2        | Starting execution sequence in -fork mode- for app name:pm2-mongodb id:0

所以问题是何时/何地我能做到

MONGODB_端口_27017_TCP_ADDR

和

MONGODB_端口_27017_TCP_端口

仅在运行容器后可用

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