Add simple health check endpoint

[omerlh]

Describe the enhancement
When using automation to provision runners (Pulumi/Terraform/Puppet/Ansible), we need a way to ensure the VM was provisioned correctly. For example, when running using GCP Instance Group, we can provide health check endpoint. GCP will start a new instance and kill the old one only if this endpoint return healthy response.

I would like to have a dummy endpoint, that return 200 if the runner has started correctly. This is a pretty standard pattern :)

Is there any movement on this? Similar to the OP, I setup self-hosted runners in an Azure Virtual Machine Scale Set. A health endpoint is required to enable auto-updating of the base OS image when Azure patches it.

I am also searching for a way to configure a health check that I can turn on in GCP managed instance group. I found that there is a network checks in Github docs here but it unrolls 4 steps and displays if it PASS or FAIL. So I can not configure the healthcheck with that.

Did you find a way?

I'm looking for something similar too. Would be nice to monitor programmatically than use the Github web page.

I am also looking for something similar here. Sad to see no movement after 5 years. What have people on this thread come up with?
