無法連接到docker mongo

Question

我正在與docker一起使用健全的項目。 在創建使用mongodb的項目並創建資源后，我嘗試運行它，但是收到一條錯誤消息，報告服務器容器無法連接到mongo。 然后，我嘗試僅運行fig up ，看看是否是無花果問題，並得到相同的錯誤。 這是我的fig.yml （刪除了不相關的注釋）：

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

關於fig up的完整錯誤報告如下（關於sane up的錯誤報告是相同的，盡管db_1的輸出更簡潔，並且客戶端也有輸出行）：

我不確定這是碼頭工人問題，無花果問題，理智問題還是帆問題。 我也無法弄清楚如何解決它。

Answer 1

將mongo容器IP替換為localhost ，您應該能夠從Docker將為您填充的環境變量中獲取該IP。

Docker還將在/etc/hosts中為您可以使用的db設置一個條目。

Answer 2

我正在通過Docker運行MongoDB，並且可以使用它：

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