copy a file with different name in destination directory using COPY in Dockerfile

Question

Can I copy a file with different Name in Docker image using COPY in Dockerfile. I am trying with below:

COPY file /dest/<renamed_file>

Answer 1

You can simply do it like COPY test.txt /dest/test_renamed.txt without a trailing /.

If you put a trailing / like COPY test.txt /dest/test_2/, it will copy the test.txt file (with the same name, of course) into the directory at /dest/test_2/.
