容器不从图像运行

Question

我有一个图像segengeation_site_sementation_site。该图像是根据以下Dockerfile和Docker-Compose文件构建的。

junaidali@ubuntu:~/Documents/segmentation/segmentation_site$ sudo docker images
REPOSITORY                            TAG            IMAGE ID       CREATED        SIZE
segmentation_site_segmentation_site   latest         e1793ab30737   3 hours ago    3.07GB

dockerfile

FROM python:3
ENV PYTHONUNBUFFERED 1
WORKDIR /app

ADD . /app
COPY ./requirements.txt /app/requirements.txt

RUN pip install --upgrade pip
RUN pip3 install -r requirements.txt

COPY . /app

docker-compose文件

version: '3'
services:
    segmentation_site:
        build: .
        command: gunicorn -b 0.0.0.0:8000 segmentation_site.wsgi 
        ports:
            - 8000:8000

进行docker-compose在显示模型时，完美地运行了图像。

junaidali@ubuntu:~/Documents/segmentation/segmentation_site$ sudo docker-compose up
Starting segmentation_site_segmentation_site_1 ... done

但是，当我使用docker运行E1793AB30737显示该图像作为容器时，它显示没有

junaidali@ubuntu:~/Documents/segmentation/segmentation_site$ sudo docker run e1793ab30737
junaidali@ubuntu:~/Documents/segmentation/segmentation_site$ 

任何人可以解释什么是运行Image Docker Run命令的正确方法，只能使用Docker Run命令运行。

谢谢

Answer 1

删除命令：Gunicorn -B 0.0.0.0:8000从您的docker -compose.yaml中删除 wsgi ：

CMD gunicorn -b 0.0.0.0:8000 segmentation_site.wsgi

否则图像不会启动任何过程

这是官方的Dockerfile文档有关更多信息。
