Non empty src/docker folder fails to build with docker

[adarshaj]

Expected behaviour

sbt docker:publishLocal should work with a source code which has some files under src/docker path

Actual behaviour

sbt docker:publishLocal fails with the following error:

[info] Step 5/15 : COPY opt /opt
[error] COPY failed: stat /var/lib/docker/tmp/docker-builder390126844/opt: no such file or directory

Thanks for the test repository and the detailed bug description and sorry for the late reply @adarshaj

If you have time I'll give you all support to fix this issue 😊

[muuki88]

Does it work if you enable the JavaAppPackaging plugin?

[dwickern]

I just ran into this. What works is to put things in src/docker/opt/docker/. For example, src/docker/opt/docker/conf/application.conf will be copied to /opt/docker/conf/application.conf in the docker image.

What's the desired behavior here? To copy everything from src/docker into the root of the image?
