garystafford/user-service repository overview

⁠microservice-docker-demo-user

⁠Introduction

One of a set of Java Spring Boot services, for an upcoming post on scaling Spring Boot microservices with the latest Spring and Docker features.

⁠Technologies

  • Java
  • Spring Boot
  • Gradle
  • MongoDB
  • Consul
  • Spring Cloud Config Server (migrating to Consul)
  • Spring Cloud Netflix Eureka
  • Spring Boot with Docker

⁠MongoDB

Common MongoDB Commands

mongo # use mongo shell
> show dbs
> use users
> db.user.find()
> db.dropDatabase()

Import sample data to MongoDB locally

PROJECT_ROOT='/Users/gstaffo/Documents/projects/widget-docker-demo'
mongoimport --host localhost:27017 --db users --collection user \
  --type json --jsonArray \
  --file ${PROJECT_ROOT}/user-service/src/main/resources/data/data.json

⁠Build Service

Build and start service locally

./gradlew clean build && \
  java -jar -Dspring.profiles.active=local \
  build/libs/user-service-0.1.0.jar

⁠Test Service

Create new user document

curl -i -X POST -H "Content-Type:application/json" -d '{
  "firstName": "Max",
  "lastName": "Mustermann",
  "userName": "MadMAX",
  "points": 44,
  "widgets": [
    {
      "product_id": "N212QZOD9B",
      "name": "Pentwist",
      "color": "Gray",
      "size": "Huge",
      "value": 60,
      "preview": "https://s3.amazonaws.com/widgets-microservice-demo/N212QZOD9B.png"
    },
    {
      "product_id": "N43WV5234S",
      "name": "Zapster",
      "color": "Green",
      "size": "Tiny",
      "value": 4,
      "preview": "https://s3.amazonaws.com/widgets-microservice-demo/N43WV5234S.png"
    }
  ]
}' http://localhost:8031/users

Get users

curl http://localhost:8031/users | prettyjson
curl http://localhost:8031/users/search/findByLastName?name=Mustermann | prettyjson

⁠Docker

Login to Docker Hub first

docker login

Build the Docker Image containing service jar. The profile will be used to run Docker container not create Docker Image

./gradlew clean build buildDocker

Create and run a Docker container

docker run -e "SPRING_PROFILES_ACTIVE=production" -p 8031:8031 -t garystafford/user-service

Import sample data to MongoDB running in container Doesn't work right now even with sudo - error inserting documents: not authorized

PROJECT_ROOT='/Users/gstaffo/Documents/projects/widget-docker-demo'
mongoimport --host localhost:27018 --db user --collection user \
  --type json --jsonArray \
  --file ${PROJECT_ROOT}/user-service/src/main/resources/data/data.json
