Building Docker fails to chmod it .sh files

I have a script in src/docker/opt/docker/bin/launch.sh.

The generated Dockerfile:

RUN ["chmod", "-R", "u=rX,g=rX", "/opt/docker"]
RUN ["chmod", "u+x,g+x", "/opt/docker/bin/server"]
RUN ["chmod", "u+x,g+x", "opt/docker/bin/launch.sh"]

See the missing / in front of opt that leads to the following error when Docker/publishLocal:

chmod: cannot access 'opt/docker/bin/launch.sh': No such file or directory

Workaround:

inConfig(Docker)(
  dockerPackageMappings := MappingsHelper
    .contentOf(sourceDirectory.value)
    .map { case (from, to) => from -> Paths.get("/", to).toString }
)

Thanks

Thanks a lot for putting together a reproducible test case.

To he honest I don’t know if I have the time to work on this, but if you would like to do I’ll give you all necessary guidance you need 😊

@muuki88 - I’ve created a repro here: https://github.com/hackcave/sbt-native-packager-docker-issue-1304 , sbt docker:publishLocal should give you the error. we can see the file exists at /opt/bin/docker/entrypoint.sh within the docker image, but the generated chmod command fails to add / prefix.
