After trying docker cp from here, it still throws a Error: No such container:path:...

enter image description here

What am I doing wrong?

  • The container is running
  • I can run docker exec commands
  • docker cp fails

From the documentation:

The docker cp command assumes container paths are relative to the container’s / (root) directory.

Source:

This means that, when your docker exec [CONTAINER] ls is affected by the WORKDIR, your docker cp is not.

What you should do from there is to run:

  1. docker exec [CONTAINER] pwd
  2. Use what this yields you in the docker cp command to have a fully qualified path to use in you docker cp command

e.g. from the httpd image:

$ docker run -d --name httpd httpd $ docker exec httpd pwd /usr/local/apache2 $ docker exec httpd ls bin build cgi-bin conf error htdocs icons include logs modules $ docker cp httpd:/usr/local/apache2/conf .

All this because the httpd image defines a WORKDIR on the folder /usr/local/apache2.
