If docker is installed you can build and run images locally.

Set the REACT_APP_API_URL variable in .env, based on your need.

Create a new EC2 instance (Ubuntu 18.04)

  • Go to AWS EC2
  • Launch instance
  • Chose Ubuntu 18.04 64 bit ( you can choose as your need )
  • Select Free tier eligible ( recommended for testing )
  • In Configure Security Group add All traffic rule and allow from anywhere ( for testing only )
  • Leave all settings as default
  • Launch
  • Create a key pair, and download it.

Connect EC2 instance from Windows machine

  • Install PuTTY
  • Open PuTTYgen, Load the downloaded *.pem file
  • Save private key ( this will save a *.ppk file )
  • Go to the AWS EC2
  • Select the instance
  • Click on connect
  • Copy the name from ssh ( the part should start with ubuntu and end with .com )
  • Open PuTTY ( NOT PuTTYgen! )
  • Go Session, paste the copied name in Host Name (or IP address) leave port as 22
  • Go Connection > SSH > Auth and browse the saved private key ( *.ppk ) in Private key file for authentication
  • Click Open
  • Click Yes ( if anything prompt up )
