This application exposes an API to lookup if a URL is malicious. The project is built in Java, Spring Boot and uses Redis as the datastore. The application is stateless and hence can be scaled to n number of instances behind a loadbalancer(eg. see kubernetes deployment) . The Redis datastore can also be scaled to create a cluster of several nodes.

To check if url is malicious GET /urlinfo/1/{URL to verify} eg.

    $ curl localhost:8080/urlinfo/1/hjaoopoa.top%2Fadmin.php%3Ff%3D1.gif

returns

    {"fullUrl":"hjaoopoa.top/admin.php?f=1.gif","isMalicious":"true"}% 

To add a URL to the malicious list POST /urladd/1/{malicious URL}

eg.

    $ curl -X POST localhost:8080/urladd/1/www.hjaoopoa.top%2Fadmin.php%3Ff%3D1.gif

response with

    {"fullUrl":"hjaoopoa.top/admin.php?f=1.gif","isMalicious":"true"}% 

  $ ./mvnw install dockerfile:build
  $ docker-compose up -d

 $ ./mvnw package && java -jar target/urllookupservice-0.0.1-SNAPSHOT.jar --redis.servername=localhost

Make sure that minikube and kubectl is installed and running

Install kubectl Install minikube

1. Create Redis Master Deployment

	$ kubectl create -f k8s/redis-master-deployment.yaml

2. Create Redis Master Service

	$ kubectl create -f k8s/redis-master-service.yaml

3. Create Redis Slave Deployment

	$ kubectl create -f k8s/redis-slave-deployment.yaml

4. Create Redis Slave Service

	$ kubectl create -f k8s/redis-slave-service.yaml

5. Create the URLService Deployment ( deploys 3 instances)

	$ kubectl create -f k8s/urlservice-frontend-deployment.yaml

6. Create the URLService Service to expose the API

	$ kubectl create -f k8s/urlservice-frontend-service.yaml

To get the API URL via the NodePort

	$ minikube service frontend --url

should return a response similar to this

	http://192.168.99.100:31323

Open the returned URL in a browser to go to the URLService home page
