Thanks for the feedback @vijaychd - we'll definitely look at this for the next release

@vijaychd I have committed ALB support in the 1.3-SNAPSHOT version in the core branch of this repository. Could you run a few tests with it? Please note that it only supports the multi-value headers feature

[vijaychd]

Thanks @sapessi
Initial test looks good to invoke the rest controller. I added /lambda-demo-api/rs/* to the controller and configured ALB for /lambda-demo-api/*. Call to api methods worked. .

[vijaychd]

need to figure out how /health and /swagger-ui.html would work. @sapessi Can that be supported?

[sapessi]

Technically it should work @vijaychd, although I have never tried. What framework are you testing with?

[vijaychd]

Spring boot. /health worked after i changed the endpoint. /v2/api-docs doesn't.

[sapessi]

Any chance you have a github repo I can use to try and replicate quickly?

[vijaychd]

Nope.
For spring boot app, usually the context path is set as
server.servlet.context-path=/lambda-demo-api

I think with ApiGateway proxy it was always getting set as /. Is it something you can add to override the context path for container.

So i will use same context on the ALB, then all endpoints should work
