Question

我有一个运行spring-boot的应用程序来访问mongodb

当我使用单独的docker run命令时，应用程序可以正常工作。但是，当我尝试将所有这些服务作为服务运行时，由于某种原因，应用程序永远无法连接到mongo。

我尝试过：

首先撰写撰写文件[下面列出]
分别运行mongo并为mongo [still。提供external_links 失败]
在撰写文件中，还提到了depends_on [仍然失败]
覆盖撰写文件中的主机名变量[失败]

搬运工-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

撰写具有外部依赖关系的文件：

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

开头

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况下，我得到的错误是：

docker inspect提供了应用程序所指的正确IP地址：

当应用程序和mongo独立运行时，它可以作为魅力

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

我错过了什么？

Answer 1

当您使用docker撰写时，您可能会使用您的服务名称访问您的容器。因此，只需更改您的spring应用程序的mongodb IP配置，如下所示：

mongo:27017

使用您的第一个撰写文件。

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

以下是**版本的示例：“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-service成功连接mongodb:27017

具有docker-compose的mongodb [SocketTimeoutException]
