Hello. I'm thinking about diving into node red. What is the minimum cpu, ram, and storage I need to run it on my vmware box? Also what OS works best with it. Thanks.
Not the best question for here, better for a node-red forum, but in any case it is very low spec.
I run it in docker exclusively, as I think a full VM for it is a waste, and my fully loaded container is ~200MB ram, never uses more than 1 .5 core equivalent on a peak basis, average is like 3% util. In terms of OS I've only run it on alpine and ubuntu, but it supports many others.
I don't believe there are published minimum specs, though. If I were to run it in a VM, I would do ubuntu server, 1 core, 512MB-1GB RAM - but that's me.
Here are my cpu/mem stats right now (5s update rate on graph).
- 100% cpu in this context=1 RPi 4 core. There are 4 cores allocated, so technically the CPU graph can go to 400% - that's just how portainer displays it.
- The cpu spikes are when I was modding/loading flows.
- I force limit my container to 512MB memory max, and have never run out
How are you getting these graphs for your docker container?
Portainer. The downside is that it doesn't historize them - it only collects the data while the container display is on-screen / real-time.
Docker, and by extension docker swarms, kind of stink for statistics vs Kubernetes. But Kube is a pain in the arse to use in home environments.
Thanks. I have a small vmware box that host my router, dns server, sql server, and more. I want it on a separate vmware so I donβt screw it up when I do maintenance on my other servers. Thanks.
that sounds pretty cool ... what kind of box & nics are you running?
I bought a Qotom i7 box from Aliexpress which has 4 Intel nics. I put inside a legrand box with all my networking there. It has been running for 6 months now with no issues.
I use a Qotom i5-5250U 4 nic for my Untangle router/firewall. Has been running great for a few years now (even if the nics do get enumerated in a different order than they physically are on the device... ).
This is the downside of qotom. I have to go to bios and take a picture of the MAC address of each nic and light it up there as well. I have sophos UTM. I have less than 50 ips so itβs free. Does untangle have free version? I would like to try it out.
Untangle has a free version but it isn't very good / useful for long term use (in my opinion). I believe there is also a trial version with all features.
They have a "HomePro" license, which is what I use, it is $50/yr (or $40/yr in 5 year renewals).
I have had >50 IP for many years (tivo, smart tvs, dvd players, phones, tablets, laptops, desktops, etc - all adds up fast, and they all need to contact the internet), so I haven't really used/followed Sophos in some time. Looks nice, though.
