We need to use the ruby24 SCL.
That means ovirt and rdo will have a dependency on ruby24 SCL, which also means the fluentd systemd service will need to know how to run the service using the scl, unless ovirt and rdo are ready to run fluentd containerized, in which case it is as simple as using the centos ruby24 scl base image, which is what openshift is doing: https://github.com/openshift/origin-aggregated-logging/blob/master/fluentd/D...
ruby24 will be needed at build time for some packages as well as at runtime.

In the OpenStack world, containers are used from kolla (or very near to that). [1]
The container in kolla itself pull in CentOS-base, centos-opstools, and RDO dependencies.
I'd think we'll need another package (and probably all dependencies) as scl versions for fluentd.
So a fluentd-ruby24-scl package, a fluent-plugin-add-ruby24-scl package, etc. etc.? That's going to be a non-starter.
It is the only way. You cannot run ruby24 and load packages built for ruby 2.0 - running fluentd on a system which has rh-ruby24 installed:
+ exec /opt/rh/rh-ruby24/root/usr/bin/ruby /usr/bin/fluentd --no-supervisor -vv /opt/rh/rh-ruby24/root/usr/share/rubygems/rubygems/core_ext/kernel_require.rb:55:in `require': incompatible library version - /usr/share/gems/gems/yajl-ruby-1.3.1/lib/yajl/yajl.so (LoadError) from /opt/rh/rh-ruby24/root/usr/share/rubygems/rubygems/core_ext/kernel_require.rb:55:in `require' from /usr/share/gems/gems/yajl-ruby-1.3.1/lib/yajl.rb:1:in `<top (required)>'
The gems in /usr/share/gems are installed via RPM and built with ruby 2.0.
It might be possible to perform this conversion at runtime:
- install fluentd from regular ruby 2.0 rpms normally - for each gem in /usr/share/gems rebuild using ruby24 into /opt/rh/rh-ruby24/root/usr/share
but this is just piling hacks on top of more hacks
I think we're going to need ruby24 branches for all of our common, collectd, and fluentd packages, and we're going to need some sort of mass conversion of all of those specs so that we can use them both with and without scl.
