gcr.io/trillian-opensource-ci/db_server:v1.6.0 has multiple media types

[coltonfreeman26]

good day all,
we are using the latest stable release of gcr.io/trillian-opensource-ci/db_server:v1.6.0 and there seems to be a bug in that build.

when doing a skopeo copy docker-archive we are running into an error with unknown media types

if you look here at the last layer you can see it is a docker type and not OCI
https://console.cloud.google.com/gcr/images/trillian-opensource-ci/global/db_server@sha256:ec1886abed03a4e739e69d0b9bb0fb7bf6e77c083e8f4f11cdd97dcc6f82bbfe/details?tab=pull

is there a plan to rebuild that or is 1.7.0 going to be out soon? this works fine with the latest build as that layer is not there but we are only able to use stable releases.

please let me know if you need any more info.

Hmm, I did a quick bit of digging around and I wonder if this is related to GoogleContainerTools/kaniko#2700 - we do seem to use kaniko for building those images (https://github.com/google/trillian/blob/master/cloudbuild_tag.yaml).

Not fixed fixed yet... need to do the re-release

Hey @coltonfreeman26 - many thanks for reporting this, I've bumped the builder version in our GCB pipeline and re-built the v1.6.0 image. The manifest seems better now, no vnd.docker in there:

Could you give it a try and see if it's working for you now?

Cheers,
