1517615 - Create a temporary worker type to test CI-only hgweb mirrors

Status: RESOLVED FIXED

(Taskcluster :: Operations and Service Requests, task)

Description

[Connor Sheehan [:sheehan]]

To test hgweb mirrors in AWS, we have linked the Taskcluster
VPC with the hg VPC in us-west-2. I'd like to be able to test the
instances (for performance/connectivity/etc issues) by making try
pushes that clone/pull from the mirror instances in the same region.
To ensure that my try pushes are executed in us-west-2 and pass
through the expected network devices, I would like to request a
new temporary Taskcluster worker type be created. This worker would
be a direct copy of the configuration for gecko-1b-linux and access
to this worker would be limited to myself (or it should be impossible
for someone to use this worker without explicitly trying to). 

Once this worker type is created, I will need some guidance on which
in-tree settings I can tweak to force the usage of the new worker.
In terms of capacity, a single worker is enough for my purposes.

K, I created https://tools.taskcluster.net/aws-provisioner/gecko-1-b-linux-usw2/view

To run a try job with this, you'll want to make a temporary commit that replaces
  aws-provisioner-v1/gecko-{level}-b-linux
with
  aws-provisioner-v1/gecko-{level}-b-linux-usw2

under taskcluster/

A search-and-replace would do a bit of a hack-and-slash job of it, but enough to see if this worked.  Alternately, you could add a morph (taskcluster/taskgraph/morph.py) to do the replacement in task.task['worker-type'] on all tasks.

Once that's done, push to try and bob's your uncle!

Thanks, Dustin!

The code that this is supporting is now live, so I'm going to remove the temporary worker.
