Support for NLBs targeting ALBs

Open gshutler opened this issue 3 years ago • 19 comments

A few weeks ago it was announced that NLBs could now use and Application Load Balancer-type Target Group (docs).

We are currently using the previously documented workaround involving Lambda which this feature is intended to replace and would love to switch to the new method.

@gshutler, thanks for bringing it to our attention. We have been considering this feature post v2.3.0 release.

Oh this is critical for an architecture I'm working on!

We're wanting this feature to get implemented as well. Our use case might be useful to others:

  • We need static IP addresses so we are using an NLB
  • We have been using an ALB and would like to continue with it for most of our traffic
  • For the app the requires the static IP's: -- we let the NLB terminate TLS connections -- we redirect HTTP to HTTPS by manually adding the ALB as a target group for the NLB

This works well, as I don't have to do anything special other than create/add a target group to the NLB and avoids having to put something behind (or in front of) the NLB to redirect to HTTPS.

However, some event eventually causes the manual configuration to get removed. Implementing this feature will allow us to remove the problematic manual configuration.

This too is a feature I could use. create a nlb and define the target for a port to a alb. Is this still on the roadmap?

45cali avatar Aug 09 '23 17:08 45cali

Also have interest in this feature. It is a surprise when looking to configure the NLB that I can use other target types but not ALB.

This is would be ideal for architectures using private link and API gateway VPC link, such as: https://aws.amazon.com/blogs/networking-and-content-delivery/application-load-balancer-type-target-group-for-network-load-balancer/

Currently looks like we will have create a shared NLB and target group + binding in terraform to achieve this.

NLB/TargetGroup CRDs or a dummy service to chain NLB -> ALB could be an option

philstevenson avatar Feb 16 '24 12:02 philstevenson

We would also like to use this feature. Any updates ? Anyone actively working on this ? Issue is open for 900 days

+1 for this feature to create NLB and set target group to an ALB.
