Docker: Provide Open Containers Initiative annotations

[bschmalhofer]

See: https://github.com/opencontainers/image-spec/blob/master/annotations.md .
Looks like this is a convention for labels on docker images.

@StefanRother-OTOBO , @svenoe

I have adapted the label in https://github.com/RotherOSS/otobo/tree/issue-277-open_containers_initiative. Could you take a look at these labels, whether the changes can be merged into rel-10_0:

                "maintainer": "Team OTOBO <dev@otobo.org>",
                "org.opencontainers.image.authors": "Team OTOBO <dev@otobo.org>",
                "org.opencontainers.image.created": "2020-08-31T07:49:32Z",
                "org.opencontainers.image.description": "OTOBO is the new open source ticket system with strong functionality AND a great look",
                "org.opencontainers.image.documentation": "https://otobo.org",
                "org.opencontainers.image.licenses": "GNU General Public License v3.0 or later",
                "org.opencontainers.image.revision": "cbb08a0f59a47a358fd07ed91484e45466e81ebd",
                "org.opencontainers.image.source": "git@github.com:RotherOSS/otobo.git",
                "org.opencontainers.image.title": "OTOBO",
                "org.opencontainers.image.url": "https://github.com/RotherOSS/otobo",
                "org.opencontainers.image.vendor": "Rother OSS GmbH",
                "org.opencontainers.image.version": "issue-277-open_containers_initiative"

The version is currently the Docker tag. For releases it probably is sensible to normalize rel-10_1_0 to 10.1.0.

[bschmalhofer]

Changed "org.opencontainers.image.url" to point to "https://github.com/RotherOSS/otobo".
On second thought I probably would leave "org.opencontainers.image.version" to contain the Docker hub tag, That is rel-10_0_3 instead of 10.0.3. . Looks more consistent to me, as there are also tags for devel versions and maybe other cases.

Hi Bernhard,

please implement it the way you think, it sounds perfekt for me.

Labels look fine in local and in Docker hub builds. Closing the issue.

[bschmalhofer]

Let's backport this to 10.0.3 as the Docker version is starting to get used. TODO:

• backport
• check labels of local builds
• check labels of Docker Hub builds

[bschmalhofer]

Labels look fine. Closing again.
