Same here, had a deeper look at MicroK8s and decided to go the Nomad route...
Unfortunately, I'm just running a homelab setup. With two publicly exposed services, but noting enterprise like.
Does that count as "in producion"? If yes, what are your questions?
Nomad is totally fine to run on low-spec machines. On my homelab, I have the following running Nomad + Consul:
Totally fine to run client and server on the same machine in a non-enterprise setup.
One stand-alone machine should also work, you just lose the failover capabilities.
IMHO not really.
There is the slight chance that DBs get inconsistent with backing up hot DB files, but in a homelab with minimal load this is usually not an issue. Same for NFS.
Just make sure you have older backups, too. Just in case the last backup was not good.
CoreDNS as my central DNS manager in my home(lab).
Currently two nodes are running CoreDNS with the same config for resilence. I really hate long DNS chains, because if something breaks in between, DNS is out ... wife and children scream ... me unhappy.
Current setup with five zones:
- .fritz.box - resolved to the provider-supplied router which also manages my network printer
- .home - forwarded to my UDM which runs DHCP in my home
- .lab.home - zone file which define s a wildcard to resolve all requests to my Traefik reverse proxy
- .consul - forwarded to Consul service catalog for service discovery
- . - everything else (internet) is either forwarded to AdGuard Home (and then to Cloudflare DNS) if the AdGuard service is running. If not, forward directly to the UDM. Nomad + Consul are amazing for this kind of templating and dynamic re-configuration.
Works quite well for me :-)
