use FROM fedora-minimal instead of centos:7

[vorburger]

as that creates a significantly (100 MB) smaller container image

[vorburger]

Don't know how you guys feel about this idea?

If acceptable, docs/ would also have to be updated accordingly.

FTR: There is also a registry.centos.org/centos/centos7-atomic which from what little I gather has a similar purpose and roughly (~ 10M diff) size, but is 7 months older; if anyone better understands which of these (community) images is the one we could be promoting here instead of the "full blown" centos one, please shout.

PS: For an exploration into possible future even much smaller images, see quarkusio/quarkus#326

@n1hility as you did the docker file we use, what do you think?

[cescoffier]

Before merging this:

[ ] The getting started guide needs to be updated
[ ] The generated docker file (created by the create project) needs to be updated

[cescoffier]

I believe we should move forward on this and open a PR on shamrock directly.

[cescoffier]

I will do that Today.

The PR has been merged in the development branch.
