I am trying to deploy Spring Boot microservices using Docker using Appmesh and EC2. I have deployed two sample microservices (https://github.com/amitgct/appmesh-hello) namely: caller-service and called-service using docker on a single EC2 instance and configured appmesh accordingly by following guide https://docs.aws.amazon.com/app-mesh/latest/userguide/getting-started-ec2.html. Currently, my applications are running on ec2 but they cannot communicate with each other and getting error on calling called-service from caller-service i.e. Unknown host. Can anyone tell me how can I specify hostname and register service with that host on EC2 and App mesh. (Note: I don't want to use kubernetes, ECS, AWS cloud map, AWS Route53) . If can provide example also then very thankful to you. Please help.
