Running Signet and Testnet nodes alongside Mainnet

I didn’t realize running multiple instances of UmbrelOS on the same machine was an option! How do I do that? I tried installing to a different path but it craps out when docker runs into name conflicts.

How do I specify different container names or prefixes or something so I don’t get this error?

Ah damn, sorry @jimmysong I wasn’t very clear with my language here:

This, in combination with running multiple umbrelOS instances (instead of trying to run multiple nodes on the same instance), is probably the easiest way to do what you’re trying to do without having to mess around with portainer, docker-in-docker, stripping out our app proxy, and translating environment variables.

I used the word “instance” way too loosely and accidentally sent you down the wrong path. I meant that it is best to run completely separate umbrelOS installs, such that each install is on a separate machine.

That being said, if you want to run multiple instances of umbrel OS on the same machine then your best bet would be to run multiple VMs. Multipass works pretty well for this in my experience: https://multipass.run/

You could set up two instances on the same machine with something like this (change --disk to what you actually need):

First instance:

multipass launch --name umbrel-testnet --disk 100G
multipass exec umbrel-testnet -- sh -c 'curl -L https://umbrel.sh | bash'

Second instance:

multipass launch --name umbrel-signet --disk 10G
multipass exec umbrel-signet -- sh -c 'curl -L https://umbrel.sh | bash'

You can also pass multipass options for CPUs and RAM.
