Incus cluster networking issue

1

Hello, I have 2 different VPS that I wanna cluster together. I joined them with normal procedure listed in documentation. I created the network as mentioned here: How to create a network - Incus documentation

But when I create an instance, after attaching the network to it, no IPs are being assigned to the instance. Sorry if it might have been asked before. Any help would be appreciated. Thanks.

Edit: Another question, is it possible to create instance replica on each node in the cluster instead of the instance residing on just one member?

Hi! Not too experienced with clusters. I think clusters work properly when you have 3+ members.

Perhaps you want to link together the two Incus installations? That is, the Incus client from each member will be able to access remotely the other member. And you can move instances between the two members from either one of those members.

I tried with 3 members as well. It’s still not assigning the IPs.

That’s cool but I would like to run the same VM/container on all nodes, is that possible?

I am guessing you’re looking for replica sets like Kubernetes. I don’t think such constructs are available out of the box.

Is there any specific config for that?

Not that I know of. As much I could tell, having replica sets in incus world is upon us to design and build. In the past, I built something similar to vmware’s site recovery manager with docker. (This was before kubernetes was released by google). Worked ok as POC but comes with complexity. Better to go with kubernetes if replica sets is an absolute must :slight_smile: Here is my design if it’s of any use/help : https://fieldday.io/droc/

Yeah, I will most likely go back to k3s. Thanks for the help!
