Smart Parking Application

This application manages smart parking sites and provides a mobile app to users.

  • The Query Vacancy function queries the vacancy of a specific spot.
  • The Reserve Spot function reserves a specific parking spot.

Prerequisites

Both functions require a running Redis and the Reserve Spot function further needs Kafka.

  • After deploying Redis, edit the REDIS_URL entry in both {query-vacancy,reserve-spot}/code/template.yml. Then create a key-value pair vacancy:10 in Redis.
  • After deploying Kafka, create a topic with the name of your choice. Then edit the KAFKA_BROKER and KAFKA_TOPIC entries in reserve-spot/code/template.yml.

Query Vacancy Function

To deploy the function,

cd faas-scheduling-benchmark/smart-parking/query-vacancy/code
npm i  # install node packages

cd ..
fun deploy -y

To invoke the function,

# The <fc-endpoint> can be found in the result printed out by `fun deploy`.
curl -s -i http://<fc-endpoint>/2016-08-15/proxy/smart-parking/query-vacancy/

Reserve Spot Function

To deploy the function,

cd faas-scheduling-benchmark/smart-parking/reserve-spot/code
npm i

cd ..
fun deploy -y

To invoke the function,

curl -s -i http://<fc-endpoint>/2016-08-15/proxy/smart-parking/reserve-spot/ \
        -X POST \
        -d '{"spot-id": "1234", "user-id": "5678", "site-id": "1234" }' \
        -H 'Content-Type: application/json'
