Question

我是Docker的新手，有一个简单的问题。假设我使用以下dockerfile在mkdir文件夹中创建了一个图像：

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。

Answer 1

到目前为止，您已经构建了映像。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

该目录位于容器内。您可以使用docker exec -it myfirstcontainer bash

输入容器

从dockerfile创建的目录在哪里，如何访问它？
