I'm going with /root/tesc. You know, because that's how I roll - always thinking outside the box! Gotta keep the exam graders on their toes, am I right?

Definitely /tmp/test. The WORKDIR / command sets the root directory, but the RUN cd /tmp command changes the working directory to /tmp before creating the file. This one's a classic Docker gotcha!

Hah, this is a tricky one! I bet the file is in /test. The WORKDIR / command sets the root directory, and the RUN echo test > test command creates the file right there in the root.

Yeah, it can be a bit confusing with Dockerfile commands sometimes.

No, it's actually in /tmp/test on the system running docker build.

I'm pretty sure the file is in /tmp/test. The WORKDIR / command sets the working directory to the root, but the RUN cd /tmp command changes it to /tmp before creating the test file.

Hmm, I see your point. But I still think it's in /tmp/test because of the RUN cd /tmp command.

I disagree, I believe the file test is located in /test within the container image.

The file test should be located in the /tmp directory within the container image. The RUN cd /tmp command changes the working directory to /tmp before the echo test > test command is executed.
