@thewtex @JonasVautherin For each dockcross images, are we pushing on dockhub both the latest and YYYYMMDD-SHA{7} tag ?

Looking at dockhub I see both but I am not sure where this happening in the CI configuration

[JonasVautherin]

It's just doing docker image push dockcross/${{ matrix.arch_name }} (which for android-arm would be docker image push dockcross/android-arm).

I must say I don't know exactly how that works internally, e.g. does it actively push a latest tag, or does the server move the latest cursor whenever a new image is pushed? I would intuitively think about the latter, but I don't know 😄

[thewtex]

By default, Docker pushes to the latest tag

We will have to re-add pushes of the date-sha tags.

[JonasVautherin]

@thewtex: it seems to me that the date tags are pushed:

20210210-84c47e5
Last pushed a month ago by dockcrossci

I did not push them manually, so it has to come from the CI, right?

[thewtex]

@JonasVautherin do you have a link for this?

When I check here:

https://hub.docker.com/r/dockcross/base/tags?page=1&ordering=last_updated

I get only get an updated latest:

This one from @jcfr message above: https://hub.docker.com/r/dockcross/manylinux2014-x64/tags?page=1&ordering=last_updated

But you're right, dockcross/base is not... 🤔

Isn't it because in the Makefile, they use $(TAG) (see here), but base does not (see here)? Let me try that...

EDIT: and actually that would answer the initial question 😆. The tag is made by the Makefile, and docker push image pushes both tags. Would that make sense?

Yes! Thanks for the follow-up -- looks like we are in good shape 💪 .

Yes, thanks @JonasVautherin for the investigation.
