我是Docker的新手，有一个简单的问题。假设我创建了一个图像来使用下面的 dockerfilemkdir文件夹：
FROM biocontainers/biocontainers:latest
USER root
RUN mkdir -p /bin/testFolder
我构建了如下图像：
docker image build -f dockerfile -t tmp:test .
消息输出如下：

我如何知道/bin/testFolder的位置以及如何访问它？谢谢。
截至目前，您已经构建了映像。下一步是运行带有docker run -d --name container-name image-name的容器，例如docker run -d --name myfirstcontainer tmp:test
目录位于容器内。您可以使用docker exec -it myfirstcontainer bash输入容器
