无法连接到 docker mongo

Question

我正在使用带有 docker 的 sane 设置一个项目。创建项目以使用 mongodb 并创建资源后，我尝试运行它，但收到错误报告，服务器容器无法连接到 mongo。然后我尝试运行fig up 看看它是否是一个无花果问题并得到了同样的错误。这是我的fig.yml（已删除无关的 cmets）：

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

fig up 的完整错误报告如下（sane up 的错误报告是一样的，虽然db_1 的输出更简洁，并且还有几行输出给客户端）：

我不确定这是 docker 问题、无花果问题、理智问题还是风帆问题。我也不知道怎么解决。

Answer 1

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

Docker 还会在/etc/hosts 中为db 设置一个条目供您使用。

Answer 2

我正在通过 Docker 运行 MongoDB，并且可以使用它：

$ export dockerip="$(docker-machine ls | awk '{print $5}' | sed -n '2p' | sed 's/tcp:\/\///' | sed 's/\:2376//')"
$ mongo --host "$dockerip" --port 27017
