Hi all, I’m fairly new to nomad and would like to know if its OK to have nomad and consul servers on the same node. I tested this on 4 ubuntu VM’s and it worked well. (one node running nomad and consul server, three nodes running both in client mode)

Hi @taypo ! Given that both Nomad and Consul servers required a good amount of resources(i.e RAM, Storage, Network I/O) in order to run properly, we generally recommend that you run Nomad and Consul server nodes on separate machines. For more information on this, please check out the following secti…

Thanks for the great links @ChipV223 Keeping those recommendations in mind, I will be building a really small cluster, with three servers and three clients. Which will handle very low loads, but production loads nonetheless. Do you think this justifies for three more nodes for consul servers?

in my opinion (OPINION), running a single node for Consul Server and Nomad Server should be OK for three worker nodes, keep adequately sized servers, not too large. Also, the documentation will always recommend separate servers, but that is “high activity” requirement. How about if you test out th…

[image] taypo: with three servers and three clients 1 server and 3 workers was my test setup. 3 servers will be running on the real thing. All nodes are 8core/16GB on-prem RHEL instances. At this level of detail, I sound like asking for free consultancy :slight_smile:, and I’m sorry about tha…

[image] taypo: three sorry, missed your second reply (low on coffee right now). at 8 CPU 16 GB these machines are quite (quite!) well powered, I think!!! BTW, Welcome to Nomad!! :+1:

A followup on this. For the managed machines (the nodes running the applications), do we have to install the nomad and consul binary on each machine? For the servers understand that its recommended to segregate them, but what about the clients?

Each client should be running a Consul Agent (if you choose to use Consul) and the Nomad Agent.

Should consul run on all nodes or just server nodes?
