i believe hiro has setup a test server at greenhost for this, fwiw.

it's a test server, so not ready.. we'll destroy/delete it when the experiments is over and will likely setup a host in Hetzner cloud instead (CX21: 5€/mth, 2vCPU, 4GB RAM, 40GB disk, 20TB traffic), fully in puppet so we can rebuild it elsewhere if/when we want.

i created hetzner-nbg1-01.tpo for this, will setup with puppet.

the machine is now setup with puppet, and collects scrape targets thanks to a pull request I issued on the prometheus module here:

https://github.com/voxpupuli/puppet-prometheus/pull/304

i also issued a PR to fix the package-based installer:

https://github.com/voxpupuli/puppet-prometheus/pull/303

the code is deployed from my "deploy" branch on github, but eventually that should go away as my PRs are merged.

i've rerolled both PRs and I believe this can be considered complete. followup in #29683 (moved) for the deployment of all the node exporters.
