Hands-On Microservices with Kubernetes

Using Go-kit to build the NewsManager service

Here is the implementation of the service itself in news_service.go. It looks very similar to an HTTP service. Let's dissect the important sections. First, it imports some libraries, including the generated gRPC code in pb/news-service-pb, pkg/news_manager, and a general gRPC library called google.golang.org/grpc. At the beginning of the Run() function, it gets the service port to listen from the environment:

package service

import (
        "fmt"
        "github.com/the-gigi/delinkcious/pb/news_service/pb"
        nm "github.com/the-gigi/delinkcious/pkg/news_manager"
        "google.golang.org/grpc"
        "log"
        "net"
        "os"
)

func Run() {
        port := os.Getenv("PORT")
        if port == "" {
                port = "6060"
        }

Now, we need to create a standard TCP ...
