platform mismatch during pack build / pack builder create

[robdimsdale]

Summary

When running pack build 0.32.0 wih the paketo builder/buildpack images, we see the following error:

fetching image: image with reference gcr.io/paketo-buildpacks/dotnet-core:0.41.0 was found but does not match the specified platform: wanted linux/amd64, actual: linux

This is true for all our images - it's nothing specific to the dotnet-core buildpack.

---

Reproduction

pack build or pack builder create with the paketo builders.

e.g. pick a Paketo Samples app and try to pack build it.

Environment

pack info

docker info

[c0d1ngm0nk3y]

This is kind of a big deal, isn't it? Should we add some integration test to make sure that pack build works with paketo?

Should we add some integration test to make sure that pack build works with paketo?

We should definitely add an acceptance test. Our current suite didn't catch this because all the tests that do pack build --buildpack <image> use daemon images. A test that uses a registry image would have caught this.
