Shell Scripting Project

1. Report the Usage of AWS Resources using Shell Scripting

For Reporting the usage of AWS resources let's write a script.

1. create a file aws_resourceses_report.sh and write script.

2.  #!/bin/bash
   
    #############################

    #Version: v1
    #this script will report aws resource usage
    #############################
    #AWS S3
    #AWS EC2
    #AWS IAM
   
    set -x 
    set -e 
    set -o pipefail
   
    #List S3 buckets
    aws s3 ls
   
    #List EC2 instance Id
    aws ec2 describe-instances | jq '.Reservations[].Instances[].InstanceId'
   
    #List IAM UserName
    aws iam list-users | jq '.Users[].UserName'
   

3. Change the file permission chmod u+x aws_resourceses_report.sh

4. Download and configure AWS CLI.

5. Execute the command. ./aws_resourceses_report.sh

6. Now if we want that everyday at 9.00 AM morning our script should be executed automatically, we should create a cronjob.

7. Install and start cron.

    sudo yum install  cronie
    systemctl start crond
   

8. and create a cronjob.

    crontab -e
    # write the job
    0 9 * * * cd /home/ec2-user && ./aws_resourceses_report.sh >> resources_report
   

This script will be executed Everyday 9.00 AM and keeps the output in resources_report file.

Thnakyou for reading.
