Install prerequisites

• docker-compose
• docker.io

  docker-compose 

Update docker-compose.yml if needed, such as PASSWORD environment variables.

Then run the application along with the database by executing:

docker-compose -f docker-compose.yml up

Volume does not mount to host path by default, therefore data will be erased when the database container is killed.

curl --location --request POST 'http://localhost:8080/' \
--header 'Content-Type: application/json' \
--data-raw '{
  "url": "https://youtube.com"

curl --location --request GET 'http://localhost:8080'

Use shorten URL for redirect

curl --location --request GET 'http://localhost:8080/<shortenUrl>'

Get HTTP response code

HTTP response code should be 304 NOT_MODIFIED

curl -o /dev/null -s -w "%{http_code}\n" 'http://localhost:8080/<shortenUrl>'
