Docker to snappy

[Vincent JOBARD]

@Loic,

I take a look at the discourse project, they visibly don't want to support
anything else than docker. There's no documentation about alternatives ways
\o/ So it will be more difficult to create snaps

Searching more on Google, I find this, that could help :
https://bcarlin.net/blog/discourse-without-docker.html

But seems that creating discourse snap will be a little bit difficult, and
the Discourse team doesn't ready to cooperate. But if someone success and
PR them the snapcraf.yaml, it could help to open discourse installation on
non-docker ready system (arm, x86)

I don't know the relationship that Canonical have with Discourse, but some
diplomatic-political stuff with upstream could help

@Anca

Good luck with this one ^^"

Cheers
Winael
