docker tag without leading v

[clux]

Out of all the projects on the front page on docker hub, no one is prefixing tags with a leading v. Consistency wise, is it possible to tag without it?

How is this related to swagger-ui?

Is that preventing you from accomplish something?

PHP has letters after the number: https://hub.docker.com/r/library/php/tags/

Node has some non consistent tags too, some start with letter some with numbers: https://hub.docker.com/r/library/node/tags/

Ubuntu seems to have it's own pattern (name-date): https://hub.docker.com/r/library/ubuntu/tags/

Well, parsing tags that are masquerading as semver, as semver.

The ones you listed (apart from ubuntu) all have valid semver tags (dash separated stuff after version is allowed). It's not a big problem, just trying to lock down version pinning so that we don't rely on floating tags everywhere. Semver enforcement is a nice way of doing that.

I don't have a problem considering it. @shockey, @ponelat - thoughts?

[ponelat]

Yeah no problem my side. Might be worth re-tagging all to the new format ( and keeping the old ones around ), its reasonably easy to do. As I wouldn't want people looking for a version, and having to guess whether it starts with a v or not.

[shockey]

Agreed @ponelat.

This isn't hard to do technically, we just need to strip the leading v off of the tag given to docker.

I imagine for new images, it's just a matter of updating our build process. For older ones, we can probably write a script that will run through the images (maybe even keep both to not break any existing dependencies?).

[shockey]

Fixed - Swagger-UI and Swagger-Editor will publish without a leading v going forward.

Thanks @clux!

This has regressed in both projects - probably due to a change in our deployment scripts.

Reopening.
