This is a simple HTTP Echo server. If you send a request value to the API, the server will return the exact same value for the response.
The build option has already been added to the Makefile file, so you can simply build with the command below.
$ make package
$ go run cmd/server/main.go
The server can also run with a docker image.
$ make docker-run
The swagger is already included in the source code, so you can just access from the local machine.
