Write a migration plan for CI infra to the disposable VMs infrastructure
Closed, InvalidPublic


The infrastructure that will let us run Jenkins jobs in disposable VM (T47499) will probably be created in parallel of our current CI infrastructure. Once we have it designed (T86171), we will need a migration plan.

I filled that task after some random discussion we had were we envisioned creating a 2nd CI infra (with a 2nd Zuul server).

In the end we only added Nodepool and a dedicated labs project for its instance. The Zuul scheduler has the logic to route jobs the different slaves.

An example is i.e. a JJB job definition needs:

node: ci-jessie-wikimedia
     - zeromq-event

And in Zuul:

- name: ^tox-jessie$
    parameter-function: offline_when_complete
