All I can tell you from my decades of Linux use is, the memory management is very odd.

But yes more free memory should help keep things running shooth, if you have the memory leave it as is

That’s how Linux manages it memory, it will use free memory as file cache till it needs it. Then free up memory for process use.

If your only half using the memory for actual services, you may want to reduce it.

Depending on what your server is doing, swap use is normal. But if it’s into swap cuz ram is full, you will find it grinds to a halt.

Use free -mh to see what the memory use is, there is a way to reduce the swapiness if your running a database server and is advised.

yeah, I think so. So nodes are over meshtastic and some are over quux

I didnt know of NNCP either, it looks amazing and super simple to setup. might have to look at how I run a NNCP forwarder to Gmail

you could do that, set the use NNCPNET_NO_NODELIST to 1.

Then your into private node https://salsa.debian.org/jgoerzen/docker-nncpnet-mailnode/-/wikis/configuration#adding-private-nodes

If you have your own domain and your DNS provider has an API, you can get a certificate for anything in your domain

OVH here, both domains, dedi server and a VPS.

Has an API to get an cert you want, even for non internet facing stuff

Snapcast might fit the bill, not sure about the 5.1 bit.

Does multi room sync

In my case I need to use a named volume for docker swarm, also I can reuse a named volume in other services. If your not using swarm then just a bind mount should be fine

with the way I do it, you can also use NFS as a backend

https://docs.docker.com/reference/compose-file/volumes/

but you shouldn’t be building out new applications and new environments on VMs or LXC

That’s a bold statement, VMs might be just fine for some.

Use what ever is best for you, if thats containers great. If that’s a VM, sure. Just make sure you keep it secure.

If you use a volume, you can mount that anywhere.

volumes:
  lemmy_pgsql:
    driver: local
    driver_opts:
      type: none
      o: bind
      device: '/mnt/data/lemmy/pgsql'

Then in your service add a volume

    volumes:
      - lemmy_pgsql:/var/lib/postgresql/data:Z

Yes, but no. There is still a lot of places using old fashioned VMs, my company is still building VMs from an AWS ami and running ansible to install all the stuff we need. Some places will move to containers and that’s great, but containers won’t solve every problem

right tool for the job mate, not everything works great in a container.

Also Proxmox is not legacy as its used a lot in homelabs and also some companys

I use proxmox to carve up my dedicated host with OVH, 3 of the vms run docker anyway.
