Support for ARM servers

(SentinelX101) #1

Continuing on from the discussion on ARM support at GitHub.

ARM support would be extremely useful for owners of small communities like myself because of the extremely low price (like the Scaleway 2GB ARM servers for €2.99) and for those who can’t afford the move from cheap shared hosting to the dedicated or KVM machines that Discourse requires.

There has also been some discussion of this on the Scaleway forums, although much of this has been around getting Discourse working without using the Docker method.

The cheapest solution for hosting?
ScaleWay review?
Your Docker installation is not working correctly on Linux/ARM
(Robert) #2

As @erlend_sh said, this is a blocker. No updates so far? Maybe Discourse could provide a list of non-ARM gems so far so that we could track here the process with respect to blocking dependencies?

(Sam Saffron) #3

Simplest thing to do is install Ruby on a scaleway copy our Gemfile and do a bundle install… what happens?

(Robert) #4

bundle install is not an issue.

However, the therubyracer and v8 gem requires some patches/different version. Otherwise, the
RUBY_GC_MALLOC_LIMIT=90000000 RAILS_ENV=production bundle exec rake assets:precompile
does not finish, but break with a stack trace.

This seems to be the upstream bug: TheRubyRacer 0.12.1 Segmentation Fault · Issue #317 · cowboyd/therubyracer · GitHub
I posted recently a comment, but did not get a response.

Scaleway patches the Gemfile and Gemfile.lock in order to use local versions that have been downloaded from elsewhere: scaleway-discourse/Dockerfile at master · scaleway-community/scaleway-discourse · GitHub

For those looking into this, a fair amount of progress has been made on this front:

Nice looks like mini racer helped here @sam!
