Cannot work with multiple LB policies

[Thai Nguyen Ngoc]

Hi guys,

I have a cluster attached 2 lb policies.

When I scale out cluster, some nodes are created, but they're only added to one ???

After, I try to detach another policy then fail: 'Failed in removing node from lb pool.'

I know that current senlin working only one policy.
And I need work multiple policies, help me ???

Thanks.

Are you attaching 2 lb policies to the same cluster? what is the use case for that?

Or do you mean that you attaching lb policy and scaling policy to the same cluster?

OK.. I want attach 2 lb policies to the same cluster.

That probably won't work. Is there a reason why you need 2 lb policies to the same cluster?

Dear Truong,

Usecase is when high traffic is comming, my backends (Autoscaling cluster) still fine, but my LB (lb policy) is bottleneck and can't serve traffic, we need to add additional LB policy to that cluster and using director LB or DNS to load balancing into two LBs. I think this is important usecase, and aws use that method.

Thanks.
