Docker-compose没有建立一个容器

[英]Docker-compose is not building one container

问题描述

我有以下docker-compose.yml 

version: '2.1'
services:
  files:
    image: busybox
    volumes:
      - ./file/input:/file/input
      - ./file/output:/file/output
   [..]  
  classificatore:
    build: classificatore/.
    volumes:    
      - ./classificatore:/src
    volumes_from: 
      - files
    ports: 
      - 8080:5000      
    command: ["python", "/src/main.py"]
    depends_on: 
      rabbit:
        condition: service_healthy

  mpeg-pre-encoder:
    build: mpeg-pre-encoder/.
    volumes:
      - ./mpeg-pre-encoder:/src
      - ./gabac_encoder:/src/gabac_encoder
    volumes_from: 
      - files    
    depends_on: 
      rabbit:
        condition: service_healthy

  rabbit:
    image: rabbitmq
    ports:
      - 5672:5672
    healthcheck:
      test: ["CMD", "rabbitmqctl", "cluster_status"]
      interval: 5s
      timeout: 2s
      retries: 20

和以下目录结构 ： 

classificatore/
   Dockerfile
   [..]
aggregatore/
   Dockerfile
   [..]
mpeg-pre-encoder/
   Dockerfile
   [..]
docker-compose.yml
[..]

mpeg-pre-encoder Dockerfile 

FROM python:3
RUN mkdir /src
ADD requirements.txt /src/.
WORKDIR /src
RUN pip install -r requirements.txt
ADD . /src/.
CMD ["python", "main.py"]

当我运行docker-compose up -d --build

并检查运行中的容器 

docker ps -a

我懂了

在构建过程中，encoder_mpeg-pre-encoder容器失败。

关于我为什么收到此错误的任何提示？

编辑3：我隔离了来自异常的错误，但我得到了一个更严重的错误。 实际上，当分类服务将数据发送到队列时，将触发mpeg-pre-encoder服务。 我认为RabbitMQ中的某些内容损坏了，如何检查我是否正确？

在mpeg-pre-encoder服务构建日志下面：

看起来构建良好，但是我一运行docker ps -a

您正在尝试使用python 3解释器运行python 2代码。 他们更改了版本之间处理异常的方式，所以现在您不能只raise 'My exception' 。

将基本容器更改为python 2或重写代码，python 2即将在2020年寿终正寝。
