A colleague of mine started to use multi-stage builds in Docker. This is a nice feature, as it helps in reducing the final image size.
I realized I can't use this feature on Fedora 29, as the
docker package is
really old (version 1.13). I was somewhat surprised, given that Fedora
always ships the latest version of everything.
A little investigation was due, so I reached out
Freenode, and now I'm reporting here what I learned.
docker package is obsolete. The
moby-engine package should be used
docker package has not been marked as obsolete, so I did
not even realize what was going on.
Well, it looks like, the package has been fixed in rawhide, so it is just a matter of time and upgrades. Still I thought to write a note on my blog, just in case it helps someone. ☺
Thanks to the
#fedora-devel people for the useful information.
