Golang Microservices

A Microservices Architecture consists of a collection of small, autonomous services. Each service is self-contained and should implement a single business capability.

Below is an example of designing and implementing Microservices using:

• Gin Gonic
• Traefik
• MongoDB

---

Movie Service Build & Run

Setup development environement

• Install Golang

• Install MongoDB

  https://docs.mongodb.com/manual/installation

• Start MongoDB

$ mongod --dbpath="[your_database_path]"

• Install neccessary Golang packages

$ go get -u github.com/swaggo/swag/cmd/swag github.com/swaggo/gin-swagger github.com/swaggo/gin-swagger/swaggerFiles github.com/alecthomas/template github.com/gin-gonic/gin github.com/sirupsen/logrus gopkg.in/mgo.v2/bson github.com/natefinch/lumberjack

NOTE: You can change host and basePath of the service by editting the file ./docs/docs.go

- Change configuration file

Update values of file ./config/config.json

{
    "port": ":8808",
    "enableGinConsoleLog": true,
    "enableGinFileLog": false,

    "logFilename": "logs/server.log",
    "logMaxSize": 10,
    "logMaxBackups": 10,
    "logMaxAge": 30,

    "mgAddrs": "127.0.0.1:27017",
    "mgDbName": "go-microservices",
    "mgDbUsername": "",
    "mgDbPassword": "",

    "jwtSecretPassword": "raycad",
    "issuer": "seedotech"
}

- Run services

• Run the Authentication service

$ cd [go-microservices]/src/user-microservice
$ go run main.go
>> [GIN-debug] Listening and serving HTTP on :8808
