MIG Multi-Zone / Regional Support

[Jeff Stone]

Hi GCE Team,

I'm new to the GCE module and have a question.  I've been looking around the group board (and Google) and haven't found the answer, so I thought I would post it here.  So far, I have been using the GCE modules to create instances, images and instance templates without much issue.  However, now I want to create a Regional Managed Instance Group.  Can you tell me if there are any plans to offer multi-zone / regional support?

Google actually recommends we use Regional over Zonal Instance Groups.  However, it appears that the gce_mig module only supports zonal instance groups.

https://cloud.google.com/compute/docs/instance-groups/

Regional managed instance groups are generally recommended over zonal managed instance groups because they allow you to spread application load across multiple zones, rather than confining your application to a single zone or having to manage multiple instance groups across different zones. This replication protects against zonal failures and unforeseen scenarios where an entire group of instances in a single zone malfunctions. If that happens, your application can continue serving traffic from instances running in another zone in the same region.

I didn't know if that support is somewhere in the GCE modules and I am just missing it...

Thanks again for the help,

Jeff

Hello Jeff,

You can create regional manged instance group which will have VMs that are distributed across a single region(e.g us-central1). For detailed information and steps to create you can refer to this link.

I hope that helps.

Hi Jeff, you say "module", so I think you're talking about python bindings not being present for r-migs. The issue in that case is that regional MIGs are still in beta, so they are in a different API subset from the "GA" or "1.0" API you're used to using. I'm not exactly sure if Python bindings are published for the beta command sets, but hopefully that's a clue to look and see if there's a beta set of modules.
