[Question] Can you build and push to a Registry an image with more than one tag with buildkit?

[gian1200]

I want to build and image, but push it to a registry with 2 tags. Is it possible? I'm currently able to do it with a single tag.

I've seen this old issue, but I'm not sure if I'm understanding it correctly.
#2141

I also have this question on Stackoverflow with more details.

Yes, you can set multiple names. If you use buildctl then separate them with a comma. In Buildx just use multiple --tag.

Yes, after writing this issue I just happen to find the original issue #797.
However, this functionality is not explained in the docs, is it? Would be nice to have it there, too.

Heya @gian1200, I've added some more info to the docs in the mentioned PR, so I'm going to close this issue 🎉

Feel free to re-open if you feel it's not resolved 😄
