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.
Agree with Proton Mail, awesome service.
Was thinking about self-hosting my email server, but Proton is just €40/year for me. Even if I value my time at only €20/hour, that means I have just two hours per year to fix issues with my email to break even.
Sure, this is /r/selfhosted, but issues with email are usually not some config changes on my side, which can be easily resolved by rolling back my latest changes from git.
Most of the issues arise from some asshat at email provider X deciding that I’m no longer trusted and blacklisting me. Resolving that issue is more like office politics than tinkering with my setup. Pretty happy if I can live my non-work life without any additional office politics.
Thanks, but no thanks.
Just have a look at Nomad.
Had a single docker machine before, and wanted to upgrade to a more distributed setup. Works like a charm now 😀
IMHO Nomad is in the sweet spot between Docker and K8s: more capable than docker, but still not the mess of disparate moving parts that is K8s.
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.
