mongodb與docker-compose [SocketTimeoutException]

Question

我有一個運行spring-boot的應用程序，可以訪問mongodb

當我使用單個docker run命令時，該應用程序運行正常。 但是，當我嘗試將它們全部作為服務運行時，由於某種原因，該應用程序永遠無法連接到mongo。

我嘗試過的

• 從撰寫文件開始[在下面列出]
• 單獨運行mongo並提供指向mongo的external_links [仍然失敗]
• 在撰寫文件中，還提到了depends_on [仍然失敗]
• 覆蓋撰寫文件中的主機名變量[失敗]

docker-compose.yaml

version: '2'
services:
 mongo:
  image: mongo:latest
  container_name: mongo
  ports:
   - "27017:27017"

 hygieia-api:
  image: hygieia-api:latest
  container_name: hygieia-api
  ports:
   - "8080:8080"
  volumes:
   - ./logs:/hygieia/logs
  links:
   - mongo:mongo
  environment:
    - JASYPT_ENCRYPTOR_PASSWORD=hygieiasecret
  depends_on:
   - mongo

 hygieia-ui:
  image: hygieia-ui:LATEST
  container_name: hygieia-ui
  ports:
   - "8088:80"
  links:
   - hygieia-api

編寫具有外部依賴性的文件：

mongo以docker run --name mongo -p 27017:27017 -d mongo

version: '2'
services:

 hygieia-api:
  image: hygieia-api:latest
  container_name: hygieia-api
  ports:
   - "8080:8080"
  volumes:
   - ./logs:/hygieia/logs
  external_links:
   - mongo:mongo
  environment:
    - JASYPT_ENCRYPTOR_PASSWORD=hygieiasecret
    - SPRING_DATA_MONGODB_HOST=mongo
  depends_on:
   - mongo

 hygieia-ui:
  image: hygieia-ui:LATEST
  container_name: hygieia-ui
  ports:
   - "8088:80"
  links:
   - hygieia-api

在上面列出的任何情況下，我得到的錯誤是：

This is very likely to create a memory leak. Stack trace of thread:

當應用程序和mongo獨立運行時，它就像一個魅力

docker run --name mongo -p 27017:27017 -d mongo

docker run --name hygieia-api --link mongo:mongo -e "JASYPT_ENCRYPTOR_PASSWORD=hygieiasecret"    -p 8080:8080 -d hygieia-api:latest

我想念什么？

Answer 1

使用docker compose時， 您可能會使用服務名稱訪問容器。 因此，只需按照以下步驟更改spring應用程序的mongodb IP配置：

mongo:27017

與您的第一個撰寫文件。

version: '2'
services:
 mongo:
  image: mongo:latest
  container_name: mongo
  ports:
   - "27017:27017"

 hygieia-api:
  image: hygieia-api:latest
  container_name: hygieia-api
  ports:
   - "8080:8080"
  volumes:
   - ./logs:/hygieia/logs
  links:
   - mongo:mongo
  environment:
    - JASYPT_ENCRYPTOR_PASSWORD=hygieiasecret
  depends_on:
   - mongo

 hygieia-ui:
  image: hygieia-ui:LATEST
  container_name: hygieia-ui
  ports:
   - "8088:80"
  links:
   - hygieia-api

這是帶有** version的示例：“ 3”

version: "3"
services:
    mongodb:
      image: mongo:3.2
      volumes:
       - ${HOME}/gocart_db:/data/db
      ports:
       - "27017:27017"

    blabla-service:
      image: blabla-service
      depends_on:
       - mongodb

在此示例中，我的blabla服務成功連接了mongodb:27017
