Use existing ALB for Load Balanced Web Services

[chris-adam-b12]

Hello,

I'd like to deploy a Load Balanced Web Service using an existing ALB (that is already used for other ECS clusters). Is it possible ?

My application is deployed by a Jenkins pipeline using copilot and I don't want to delete the load balancer and reconfigured the old one every time.

Thank you

Hi @chris-adam-b12 !

Thank you for the feature request, it seems to be related to: #1457

To help us deliver the right thing, would the imported load balancer already have a port 80 or port 443 listener?
If there is already a port 443 listener I assume that you have your own managed certificates attached to it, is that correct?

Hi @efekarakus ,

Indeed, it is related.

Yes, my load balancer have both port 80 and 443 listeners. I also have a certificate attached.

We'd like to have this feature too.

The ALB could be imported when the environment is created (like VPC and subnets), and certificates handling should be disabled.

Same request. this feature would be really helpful.
Since a single ALB can now be used to configure different services, I think it would also be important to have the different conditions for ALB routing rules, available as properties in the manifest. e.g host headers, HTTP headers, Query string, etc.

Agreed, this would be really helpful. ALBs are the most expensive part of Copilot's load balanced web services for me - with spot tasks the compute costs can be low, but if I have a bunch of small apps that all need dev/qa/prod environments, then I'm going to spend a LOT on ALBs. Like maybe 50-75% of the total costs. It's nice that related services can reuse the same ALB but that is not a preferred way to go about organizing apps which should actually be entirely separate.

I am looking for a quick and easy way to build many Feature Environments. Copilot seems to solve that, but I am disappointed that it will be costly if I cannot use my existing ALB...

This feature would help in increasing cost efficiency for lower envs.
