Docker构建创建并标记Docker运行无法找到的映像

Question

我得到了一个Docker容器中的项目。我已经设法构建了Docker容器映像并对其进行了标记，但当我运行它时，我遇到了问题。

bash-5.1$ docker build -t game:0.0.1 -t game:latest .

bash-5.1$ sudo docker run -it -e DISPLAY=$DISPLAY -v /tmp/.X11-unix:/tmp/.X11-unix game:latest

它似乎没有找到游戏：最新的图像，尽管上面命令的输出说它只是创建了它

我也会在登录会话后尝试这样做。

我试着运行59b472b693f2(它是什么，是容器哈希代码吗？(：

bash-5.1$ docker run 59b472b693f2
python3: can't open file 'start.py': [Errno 2] No such file or directory
bash-5.1$ ls
data_collection  demonstrateur.ipynb  demo.py  Dockerfile  examples  README.md  requirements.txt  serious_game  start.py  test
bash-5.1$ 

以下是可用图像列表：

bash-5.1$ docker images

python3: can't open file 'start.py': [Errno 2] No such file or directory
bash-5.1$ 

我试图将其添加到Dockerfile中，但仍然得到了相同的错误：

这是我的Dockerfile:

在您发布的第一块代码中，它显示Successfully tagged game:latest和Successfully tagged game:0.0.1，但在docker images输出中，您看不到这些图像。查看docker images的输出，我发现上次构建名为serious-game的映像是在1小时前。我猜您试图重命名图像，但图像ID没有更改。

您可以尝试使用docker image rm命令(docs(删除旧映像，然后尝试重新构建它。要执行的命令序列是下面的代码块。数据应该是安全的，因为我看到你在使用卷(我认为你知道你在做什么(。

docker image rm 59b472b693f2
docker build -t game:0.0.1 -t game:latest .

序列59b472b693f2是Docker本地环境中映像的唯一ID(您可以假设它是一个与数据库中用于索引的ID类似的ID(。
