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

We got an old style phone when we went to see the northern lights

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

I will be looking for cheap dishwashers when we need a new one, that don’t even know what the internet is.

Or making a shit appliances network, all the WiFi crap can live on that

I’m with him, what happens when my internet drops out (which it does on the reg)?

I can’t run the dishwasher cuz AWS us-east-1 is down

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

would agree the hardware would run everything fine

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.

If your router is setup to only allow in the ports with a service hanging off it, like SSH. Then a firewall wont add anything your router doesnt.

On the flip side, if your running any kind of VPS or directly accessible server, like a VPS or dedicated server. Then a firewall is required.

Now protecting your server from other things on your local network might something you want to do, think IoT stuff getting popped and being used to hack other things on the network

As a homelabber and systems admin, I would start with learning how to use Linux on the command line.

It’s all well and good looking at docker, but if you don’t know how to move about or edit on the command line. Your going to get stuck real quick.

Once your happy doing simple tasks on the command line, I would actually look at running something like wordpress on a pi or VPS. That will help you understand how to connect services together, and cement your basic command line knowledge.
