A better way for building instance types list

[jameswnl]

Currently we are using this rake task which also involve pre-rake manual steps to retrieve info from multiple website.

This procedure has to be done before each MIQ release. In between releases, user now can use this (yet to be released) mechanism to capture new instance types which missed the release train.

A better solution will be a web service that is always available to allow MIQ to retrieve. (Similar to what Azure has)

What we can do for now is to

1. contribute to https://github.com/powdahound/ec2instances.info to enhance its json output to contain what we need

2. Adapt and move the logic in this rake task to the ManageIQ::Providers::Amazon::CloudManager::RefreshParser.get_flavors and/or ManageIQ::Providers::Amazon::InstanceTypes.instance_types

3. (MIQ would need access to http://www.ec2instances.info/)

I have 2 PRs moving in that direction.

• For 1., Add CPU details vantage-sh/ec2instances.info#270 (merged)
• For 2, Improve instance_types.rake logic #301 (merged)

@durandom @bronaghs @blomquisg FYI...

[juliancheal]

I love the idea, but don't like the thought of going to a third party.

[jameswnl]

@juliancheal yeah, I agree it's not ideal to depend on a 3rd party. But we have been depending on the same 3rd party, ec2instances.info (since day 1?).

Plus, this 3rd party is open source and it is depending on AWS's published html.

[juliancheal]

@jameswnl oh, I thought we read it direct from AWS's published pages.

[juliancheal]

@jameswnl as ec2instances.info is open source, could we mirror it?

Thank you for all your contributions!

@jameswnl are we still pursuing this?

[jameswnl]

@juliancheal closing this because #396 seems a simpler approach.

[juliancheal]

@jameswnl I had a feeling @AlexanderZagaynov would have a solution :)

[AlexanderZagaynov]

yeah, there is the first one #436
and if everyone likes that approach, I'll do the PRs for two other related issues too in the same way
