run jaeger ui by visiting http://localhost:16686

Run jaeger container and then run our go server using:

Generating Swagger Go Client

First we will generate swagger client for golang

• on root level create directories gen/client
• run make command make swaggerClient
• once files generated without error run go mod tidy

Now make sure our server is running

go run 1.go

now cd into cmd/rest/client and run go run client.go
