【问题描述】：
我创建了一个镜像来运行带有 chrome 的 docker 容器。下面是我的代码。我的 dockerfile 确实编译成图像。但是，每当我尝试从图像运行容器时，我都会收到错误“未找到 Bootstrap.sh 文件”，尽管文件存在于我的 FileSystem 快照内部图像中。您可以查看屏幕截图。
请帮我解决这个问题，我是 docker 新手。

【问题讨论】：
-
docker run -it your_image "/bootstrap.sh" -
我试过但得到这个错误“docker：来自守护进程的错误响应：OCI 运行时创建失败：container_linux.go:345：启动容器进程导致“exec：\”bootstrap.sh\”：可执行文件在 $PATH 中找不到“：未知。”
-
docker build --no-cache -t your_image .似乎窗口解释了路径磨损，尝试docker run -it your_image "\bootstrap.sh" -
` \"bootstrap.sh\":` 它应该像` \bootstrap.sh":
-
或者尝试在 gitbash 中运行命令
