Skyscanner clone prototype

microservices based prototype of skyscanner clone

aws-deployed-version => Not available at the moment

Design

• There are three Docker containers - one with React app, one with Spring Boot app and one with Postgres db
• When the app starts - db is populated with random flight data
• Containers are waiting for each other with help of wait-for-it.sh
  • Spring Boot app waits for Postgres db to be ready
  • React app waits for Spring Boot app to be ready

Usage with Docker

• Prerequisites:
  • Docker & Docker Compose installed
  • Ports 3000, 3001 and 5432 available [not required for Docker Toolbox]
  • Chrome browser
• Clone/download the repo
• In core folder run
  • [to start the app]:

    docker-compose up 
    

• Visit http://localhost:3000/ [Linux, Mac OS and Docker Desktop on Windows 10] or http://[host-ip]:3000 [Docker Toolbox] (default is http://192.168.99.100:3000/)
  • To get docker host ip with Docker Toolbox run

    docker-machine ip
    

Deployment

• The app is deployed to a Docker Swarm cluster running on a single node (AWS EC2 t2.micro)
• The following commands were used to deploy the app:
  • Create Docker swarm cluster

    docker swarm init --advertise-addr 172.31.19.6
    

  • Create stack of services for skyscanner-clone-prototype

    env HOST_IP=3.14.147.254 docker stack deploy -c docker-compose.depl.yml skyscannerStackk
