Sample CRUD App

Quick Start with Docker

Create a network that is called crud-app:

docker network create crud-app

Start a standalone MongoDB instance:

docker volume create --name mongodb_data
docker run -p 27017:27017 -d --network=crud-app \
            --name mongodb \
            -v mongodb_data:/data/db \
            --restart=on-failure \
            mongo:4.0.2

Start a standalone Redis instance:

docker volume create --name redis_data
docker run -p 6379:6379 -d --network=crud-app \
            --name redis \
            -v redis_data:/data \
            --restart=on-failure \
            redis:5.0.6

Start backend:

docker run -d --network=crud-app \
            --name backend \
            -e MONGODB_URI="mongodb://mongodb:27017/sample-app" \
            -e JAVA_OPTS="-Dspring.profiles.active=local-docker -Xms125m -Xmx250m" \
            --restart=on-failure \
            cunal/demo-backend:51e393ef4be964e1c0a11cbc869d397a82700190

Start gateway:

docker run -p 9091:80 -d --network=crud-app \
            --name gateway \
            -e DEMO_BACKEND_SERVICE="http://backend" \
            -e JAVA_OPTS="-Dspring.profiles.active=local-docker -Xms125m -Xmx250m" \
            -e REDIS_HOST=redis \
            -e REDIS_PORT=6379 \
            -e RATE_LIMIT_ENABLED=true \
            -e RATE_LIMIT_REPOSITORY=REDIS \
            -e RATE_LIMIT=4 \
            -e RATE_LIMIT_REFRESH_INTERVAL=1 \
            --restart=on-failure \
            cunal/demo-gateway:51e393ef4be964e1c0a11cbc869d397a82700190

Start frontend:

docker run -p 5000:5000 -d --network=crud-app \
            --name frontend \
            -e REACT_APP_BACKEND_URI=http://localhost:9091/api/demo-backend \
            --restart=on-failure \
            cunal/demo-frontend:51e393ef4be964e1c0a11cbc869d397a82700190

Check everything is working properly:

docker ps
