url-shortener

Requirements:

Cassandra:

A docker-compose file is included for this purpose.\

docker-compose -f cassandra-cluster.yml up

Note: This will take several minutes for the Cassandra nodes to come up the first time.

Environment Variables:

• CASSANDRA_HOST: The location of a cassandra host
• FRONT_HOST: The front-facing portion of the URLs to be returned to the user.
  e.g. Setting FRONT_HOST=http://127.0.0.1:8080 means the service will return shortened URLs of the form http://127.0.0.1:8080/lookup/6UnHLut8NR

Scala & sbt:

To run using sbt:
FRONT_HOST=http://127.0.0.1:8080 CASSANDRA_HOST=172.19.0.2 sbt run
