Nomad

I want UP ELK cluster by nomad. I will use separate type servers for every elastic role.
ELK data and muster will use big server and kibana will use small server.
How I can tell nomad launch kibana groupe to small server - only?

Although the title says affinities you may also want to check out constraints (which is also mentioned in the article)

Indeed. I thought this site/ doc captures them both. :blush:

THNX it’s true. I used constraint and it’s work.

Hmmm I have now strange situation.
From my groupe1

constraint {
  attribute = "${node.datacenter}"
  value = "dc1"
  distinct_hosts = true
}

and from groupe2

constraint {
  attribute = "${node.datacenter}"
  value = "dc2"
  distinct_hosts = true
}

But now i see that task from groupe1 is spinning on server which has lable dc2.
Why?
When I deleted
distinct_hosts = true
My application is started right.
