can a puppet run tell puppet master to run puppet on other host based on previous events (e.g. new host)?

[Alex Leonhardt]

hi,

to ease orchestration and changes to systems with dynamic configurations / e.g. configure load balancer based on how many webs are known to puppet / I was wondering if it's possible to make a puppet master trigger puppet runs on e.g. the load balancers *after* it got told there is a new host that got class 'web' applied ?

in particular am looking for someting like saltstacks salt-reactor w/ salt-mine system

thanks!

No.

Maybe you can do it if you have a script that monitors a puppetdb? But this is not what you are asking, so the answer will be no.

The master is involved only on giving the ENC data and doing the catalog compilation.

Alex,

The more complete idea would be to trigger when resources have
actually been applied. So I would probably consider a report listener
for this kind of thing, as it shows when a resource has changed rather
than compiled.

I think Chris Spence has a tool for this kind of thing that uses MCO
to trigger the runs:
