For example, Skopeo ( https://github.com/projectatomic/skopeo) can do this: ./skopeo inspect docker://amouat/network-utils { "Name": "docker.io/amouat/network-utils", "Digest": "sha256:fcb208490240b82af947a24b233cbc208ee9761035731bddbeb888bb33b71d14", "RepoTags": [ "latest" ], "Created": "2016-11-11T12:59:09.461996171Z", "DockerVersion": "1.12.3", "Labels": { "org.label-schema.build-date": "2016-11-11 12:57:22+00:00", "org.label-schema.docker.dockerfile": "/Dockerfile", "org.label-schema.vcs-type": "Git", "org.label-schema.vcs-url": " https://github.com/amouat/network-utils-container"; }, "Architecture": "amd64", "Os": "linux", "Layers": [ "sha256:386a066cd84a33a04d560c42bef66d1dd64ebfc76de78550e5fd0f8d57778bca", "sha256:44f8daaa54e7d5a2fc678d26ae691ab0f7c6a51bb7346fbdd581697f22b1a120", "sha256:c6a1e73879c72e17e7a917b197d0927494f48f42bd560f2ff61ab8efa3814830" ] } On Thu, Dec 1, 2016 at 10:57 AM, <hu.zhiji...@zte.com.cn> wrote: For #1, I think the requirement is that before pulling the image to local registry, one can get its metadata about the version info before hand, thus save time and space spend on pulling wrong images. I don't know if the info in docker label can be retrieved before before pulling the image to local registry. If not, holding such info in docker label may be not a good solution since we have to pull the image first. Another thought is how about let the kolla build command to generate a report about what component version it used to build for each image and just let it output this report to a file or stdout? Then this well formatted output can be published along with the images(docker save...) but not inside of images.

This solution is gaining traction in the docker community, and integrates well with external tools e.g. https://microbadger.com. One of the maintainers of this project (Adrian Mouat) works in the same room as me and I've cc'd him in case he has any additional insight or perspective that may be useful. Unfortunately this does not provide a solution to the 2nd problem, and currently it is not possible to query labels from within a container. I think Steve's suggestion of a simple shell tool to query the containers package manager(s) and produce a report is probably the right way to go: but we should draw up a specification that scoped what data we collected in such a manifest as if we simply do the equivalent of 'rpm -qa' then I think Paul's point is valid and we don't gain much from the exercise.

I don’t have a clear solution to obtaining version manifests for container content or the upstream container version. Perhaps someone in our broader community may have an answer. The best I’ve got is we could add a general shell command that can be run with docker exec to obtain a proper version manifest of both 1 and 2 (formatted in YAML or plaintext). This could be placed in the base container image to enable a general diagnostic and certificate of origin tool. Perhaps someone has a better solution?

I am a contributor of Kolla. Excuse me, I have a question to bother you. The question is that how to get openstack component version from a running container or image. you know , the version info is wrapped by the container, it is not easy to get them there are two type of versions one: version in a image, two: version in a running container two is easy, for example , we can get it by calling docker exec... but how to get the one, Is there any way, Thanks. __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev -- Pete Birley / Director pete@port.direct / +447446862551 PORT.DIRECT United Kingdom https://port.direct This e-mail message may contain confidential or legally privileged information and is intended only for the use of the intended recipient(s).
