So supposedly I have a following file structure where ‘<‘ is current terminal directory

• FolderA
  • text.txt
• FolderB <
  • Dockerfile

And I want to copy text.txt into the container and print the content.

Dockerfile:

FROM alpine
COPY ../text.txt .
CMD cat text.txt

Issues start even on the docker build . stage because when you try to do so you get following error

ERROR ...: "/text.txt": not found
(skipped few words with ‘…’)

I was unable to find any clarifying answers on the internet. So is it possible to copy text.txt without using Docker-Compose?
