图片中的容器不是运行

Question

我有一张图片 segmentation_site_segmentation_site。该图像是根据以下 Docker 文件和 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

Docker文件

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-编写文件

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

docker-compose up 运行完美呈现图像，加载的模型显示出来。

junaidali@ubuntu:~/Documents/segmentation/segmentation_site$ sudo docker-compose up

但是当我运行使用docker run e1793ab30737将该图像作为容器时，它没有显示输出

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

任何人都可以解释一下运行图像 docker 运行命令的正确方法是什么，因为当这个图像将被拉到部署位置时，它只能是运行使用 docker run 命令。

谢谢

从您的 docker-compose.yaml 中删除 command: gunicorn -b 0.0.0.0:8000 segmentation_site.wsgi 并将其放入您的 Dockerfile 中，如下所示：

CMD gunicorn -b 0.0.0.0:8000 segmentation_site.wsgi

否则图像不会启动任何进程

Here is the official Dockerfile documentation 了解更多信息。
