This is a Spring boot project built with Spring Tool Suite (STS). You can download/clone the repo and import it as an existing project into workspace in STS. It is a Maven project so it has all required dependencies in the pom.xml.

Prerequisites

You need the following installed and available in your $PATH:

• Java 8
• Apache maven 3.0.3 or greater

This is a simple tutorial I followed to install them.

AWS scripts:

1. Launch ec2 instances

launchEC2Instance.sh launches a EC2 instance and configures it with userdata.sh, then use Route53 to configure it with our domain name neu-csye6225-spring2017-team-4.me.

2. Set up S3

setupS3.sh creates a bucket "s3.neu-csye6225-spring2017-team-4.me" on AWS S3 and if the bucket exists it gives a message "Bucket already exists". We enable versioning to the bucket and grant read permission for all users

3. Set up the web security group

setupWebSecurityGroup.sh creates a "web" security group and opens port 80 and 443 for incoming traffic from anywhere.

4. Set up the database security group

setupWebSecurityGroup.sh creates a "db" security group and opens port 3306 for incoming traffic from 'web' security group.

5. Launch a MyQql RDS instance

launchMysqlRdsInstance.sh launches a mysql instance with no public accessability.

6. Create DynamoDB tables

createDynamoTable.sh creates a dynamodb table and if table exists it gives a message "already exists" . We have table name as csye6225 with attributes personId in Number and username as String.

7. Create IAM policies

createContinuousDeliveryIAMPolicies.sh creates three policies 'CodeDeploy-EC2-S3', 'Travis-Upload-To-S3' and 'Travis-Code-Deploy'.

8. Create the travis user

createContinuousDeliveryTravisUser.sh creates a 'travis' user with 'Travis-Upload-To-S3' and 'Travis-Code-Deploy' policies attached.

9. Create IAM roles

createContinuousDeliveryIAMRoles.sh creates a 'CodeDeployEC2ServiceRole' with 'CodeDeploy-EC2-S3' policy attached, and a 'CodeDeployServiceRole' with 'AWSCodeDeployRole' policy attched.

10. Set up a S3 bucket for CodeDeploy

setup_codedeploy_s3.sh creates a S3 bucket to deploy the application archive.

11. Create the CodeDeploy application

createContinuousDeliveryCodeDeployApp.sh creates a CodeDeploy application 'jobportal' and add the ec2 instance to it.

12. appspec.yml & .travis.yml

Configuration files for continuous deployment.

13. restartapp.sh

It's used by CodeDeploy to restart the application on the EC2 instance. It's not meant to be used by users.

How to run python sccript.

This connects to the dynamodb and gets the json data from the table. We have to provide username in the GET request URL. Set environment variables:

• export AWS_ACCESS_KEY_ID="you accesskey"
• export AWS_SECRET_ACCESS_KEY="your secret key"
• Run the get_python.py file on server and access the {localhost:8080}/?name={username}

Updates

• Add anti XSS filter;
• Update AJAX to jQuery AJAX;
• Upload user image to S3 and display the image on candidate profile page
• Add email pattern control
• Add empty entry alert
• Added loggers using slf4j which creates external file for logger
• Added python rest api , GET request gets data from AWS dynamo db
