我是Docker的新手，有一个简单的问题。假设我使用下面的dockerfile为

mkdir

文件夹创建了一个图像：

FROM biocontainers/biocontainers:latest

USER root

RUN mkdir -p /bin/testFolder

我构建的图像如下所示：

docker image build -f dockerfile -t tmp:test .

如何知道

/bin/testFolder

的位置以及如何访问它？谢谢

到目前为止，您已经创建了图像。下一步是使用

docker run-d--name container name image name

运行容器，例如

docker run-d--name myfirstcontainer tmp:test

目录位于容器内部。您可以使用位于

/bin/testFolder

中的

docker exec-it myfirstcontainer bash
输入容器。检查my。我收到来自守护程序的错误响应：container 450B1CDB06C10A5C20B5D4DFEA1FE9E91BAF2C4345565BD29CFE00E6CB89AD未运行
：当我运行docker exec-it myfirstcontainer bash时意味着您的容器要么崩溃，要么执行完毕。您可以通过发出以下命令直接在bash
中启动映像：docker run-it/bin/bash
@bison72您只能在容器运行时进入容器。运行docker ps以列出正在运行的containers@bison72当前dockerfile未运行任何进程，这就是原因。试试这个例子
