kube-vip as a lb?

[ndrwstn]

In his video on this topic, @timothystewart6 said he couldn't get kube-vip to work as a load balancer, which is why we're still using metallb. I didn't think much of this at the time--nor did I mind, as I like metallb--but after getting this repo working with kube-vip using BGP, I just found out that a single node can't use BGP in two deployments (e.g. kube-vip and metallb) as it leads to 'peer flapping', which I need to solve.

The simple solution to this is likely to just use kube-vip as a load balancer, but before I start down that rabbit-hole, I wanted to see if there was some Very Good Reason why kube-vip didn't work in the first place? Anyone have any ideas?

It might have been a bug or a configuration issue at the time. I am also considering making metal-lb optional. #172

[timothystewart6]

Hey, agree with all of these statements. I would love to give kube-vip some more flexibility as well as the option to exclude MetalLB. I too fee like GitOps is the way to go vs. installing anything via ansible see #192 (comment)

Don't disagree, but then whats the point of this vs k3s-io/k3s-ansible ?

Is that one too stale? Maybe I missing repo functionality knowledge and so am missing the point....

[timothystewart6]

No clue about the differences, last I checked that didn't work nor was supported. This ones creates an HA cluster with HA service load balancer and HA k8s API.

[rr4444]

Def def, totally agree. So:

1. if the official k3s ansible repo is verging on abandoned
2. and this repo's ansible element is instead changed to be only for k3s deployment
3. meaning the kubevip +/- metal-lb combo moves from ansible to k8s yaml deployment

then this repo becomes THE community maintained ansible k3s deployment repo (plus bells and whistles)

That's still a very valid and valuable FOSS role.

Or am I misunderstanding things?

Frankly, I am trying to work out the most sensible k8s + kubevip + kubevip cloud controller combo. And this repo feels nicely alive to have legs for the future.

[timothystewart6]

That's exactly right. I couldn't find one that worked, so I forked and built this instead 😄
