Building image from Dockerfile - COPY failed: no source files were specified

[welo78]

Hello all, first of all thank you for this amazing terraform resource.

Secondly, I am having hard time wrapping my head around issue I have with building your terraform resource from dockerfile. I was under the impression that by running the docker build command with your dockerfile an image should be created which then can be used for concourse pipelien purposes.

As you can see it keeps failing on Step 10/12 : COPY $TARGETARCH/terraform/* /usr/local/bin/ COPY failed: no source files were specified

Am I missing something ? I tried running your dockerfile on both Windows and Ubuntu docker engine.

Sorry for the delayed response. Use this script to build the docker image: https://github.com/ljfranklin/terraform-resource/blob/master/scripts/docker-build. Ideally the dockerfile would be a self-contained build but this is an artifact of how the CI pipeline works.
