Is it possible to dynamically select instance type

[kaykhan]

Hi friends, Is there some way that i can dynamically set the instance type in the ci/cd github actions config file.

   runs-on: self-hosted

e.g

   runs-on: self-hosted, t2.small

what is the best way to get this dynamic behaviour and let the dev decide the size of the node that is required to run their ci/cd job.

Is there also a way to dynamically select the base image?

How far can i get in achieving either of these 2 with this repo

---

It seems like if i want to dynamically select the instance type, i would need to create a new runner deployment for each? Using the nodeSelector, it would be able to provision a node for the ci/cd pod?

apiVersion: actions.summerwind.dev/v1alpha1
kind: RunnerDeployment
metadata:
  name: runner-t3-small
  namespace: actions-runner-system
spec:
  replicas: 1
  template:
    spec:
      organization: <>
      image: <>
      nodeSelector:
        aws/node-type: t3.small

We have multiple organisations and i want to be able to allow the dev to spinup a new node to use for their ci/cd, allowing them to decide the instance type (and possibly base image). Is this possible?

Hi @kaykhan, if you're not yet too invested in ARC, you might want to have a look at RunsOn, which allows to dynamically specify runner type and runner image based on labels.

For instance:

- runs-on: ubuntu-latest
+ runs-on: runs-on,runner=16cpu-linux,image=ubuntu22-full-x64
