无法连接到docker mongo [英] Cannot connect to docker mongo

问题描述

我正在使用 sane 和docker建立一个项目.创建使用mongodb的项目并创建资源后，我尝试运行它，但是收到一条错误消息，报告服务器容器无法连接到mongo.然后，我尝试仅运行 fig up 来查看它是否是无花果问题，并得到相同的错误.这是我的 fig.yml (删除了不相关的注释):

I am setting up a project using sane with docker. After creating the project to use mongodb and createing a resource I tried running it, but got an error reporting that the server container could not connect to mongo. I then tried just running fig up to see if it was a fig problem and got the same error. Here is my fig.yml (irrelevant comments removed):

db:
  image: mongo:latest
  ports:
    - "27017:27017"
server:
  image: artificial/docker-sails:stable-pm2
  command: sails lift
  volumes:
    - server/:/server
  ports:
    - "1337:1337"
  links:
    - db

关于 fig up 的完整错误报告如下(关于 sane up 的错误报告是相同的，尽管 db_1 的输出更简洁，客户端也有输出行):

The full error report on fig up is as follows (the error report on sane up is the same, although the output from db_1 is more terse and there are also lines of output for the client):

我不确定这是码头工人问题，无花果问题，理智问题还是帆问题.我也无法弄清楚该如何解决.

I'm not sure if this is a docker problem, a fig problem, a sane problem, or a sails problem. I also cannot figure out how to fix it.

推荐答案

用mongo容器IP替换 localhost ，您应该能够从Docker将为您填充的环境变量中获取IP.

Replace localhost with the mongo container IP, which you should be able to get from an environment variable that Docker will populate for you.

Docker还将在您可以使用的/etc/hosts 中为 db 设置一个条目.

Docker will also set up an entry for db in /etc/hosts that you can use.
