Software requirements

Step 1 :: Building User service with Docker

$cd services/user
$docker image build -t user .
$docker container run --rm -p 3000:3000 \
 -e PROCESS_TYPE=web \
 -e NODE_ENV=production \
 -e DB_HOST=xxx \
 -e DB_USER=xxx \
 -e DB_PASSWORD=xxx \
 -e DB_DATABASE=xxx \
 -e DB_PORT=3306 \
 user

Working with docker compose

  • Create database
  • Seeding data to database (create tables)
  • Start user service
// Create
$docker-compose up -d

// Delete
$docker-compose down

API Testing with Postman by using newman command

$cd testing
$newman run user-service.postman_collection.json

Step 2 :: Building Product service with Docker

$cd services/product
$docker image build -t product .
$docker container run --rm -p 3000:3000 \
 -e PROCESS_TYPE=web \
 -e NODE_ENV=production \
 -e DB_HOST=xxx \
 -e DB_USER=xxx \
 -e DB_PASSWORD=xxx \
 -e DB_DATABASE=xxx \
 -e DB_PORT=3306 \
 product

Working with docker compose

  • Create database
  • Seeding data to database (create tables)
  • Start product service
// Create
$docker-compose up -d

// Delete
$docker-compose down

API Testing with Postman by using newman command

$cd testing
$newman run product-service.postman_collection.json

Step 3 :: Building API gateway for User services with Docker

$cd gateway
$docker image build -t gateway .
$docker container run --rm -p 3001:3000 \
 -e JWT_SECRET=secret \
 -e USER_WEB_SERVICE_HOST=xxx \
 -e USER_WEB_SERVICE_PORT=3000 \
 -e PRODUCT_WEB_SERVICE_HOST=yyy \
 -e PRODUCT_WEB_SERVICE_PORT=3000 \
 gateway

Call API from Gateway

Step 4 :: Building Frontend with Docker

$cd frontend
$docker image build -t frontend .
$docker container run --rm -p 3002:3000 frontend

Open url=http://localhost:3002/login in browser

Step 5 :: Run All-in-one with Docker compose

Build and deploy

$docker-compose -f docker-compose-build.yml build
$docker-compose -f docker-compose-build.yml up

// Delete all
$docker-compose -f docker-compose-build.yml down

Deploy only

$docker-compose -f docker-compose-deploy.yml up

// Delete all
$docker-compose -f docker-compose-deploy.yml down

Open url=http://localhost:3002/login in browser

Next ==> Deploy with Kubernetes on Google Kubernetes Engine (GKE)
