I have two microservices communicating using gRPC.Both are docker applications deployed on ECS. How do I configure them to use AWS ALB?In documentation it says ALB supports HTTP/2, however I can only see HTTP1 settings. My application has one gRPC port and one health check API at 8080.How do I configure that on ALB?
I don't believe you can.
ALBs "support" HTTP2 but only in so far as they can accept HTTP2 and de-multiplex it before forwarding on HTTP1.
You can use AWS's newer "NLB" though that has other wrinkles. More details of doing this https://blog.prefab.cloud/blog/grpc-aws-some-gotchas
