Solved–Assignment #4 adduser and Cloud Computing– Solution

Description

Overview

In this assignment, you will be writing a shell script wrapper for user management using usermod, userdel, and useradd as building blocks. Include a verbose option to output what is happening step by step. Alongside this, you will be writing a python script that utilizes the AWS SDK to provision a t2.micro EC2 instance. For both of your scripts, create appropriate documentation in your git repo’s README.md file.

Submission

No webcampus submission. Follow the link provided below to create a GitHub classroom repo to push your code to. I will be checking the two scripts and the readme for documentation.

To-Do

For Git repo

• Follow link instructions: ​https://classroom.github.com/a/GlVuYrot

Adduser Script:

• Prompt for username, full name, and password

• Create /etc/passwd, /etc/shadow, and /etc/group entries

• • Make sure syntax is correct before you make changes to actual files

• • For /etc/shadow, see sample code for generating password hash

• Create home directory, chmod and chown it

AWS Script

• Create SSH keypair to connect to instance with via aws SDK

• • create_key_pair() method: ​Documentation

  • Save the private key in it’s return JSON object

• • • Save to a .pem file in current directory, with permissions 400

• Create an t2.micro EC2 instance

• • create_instances() method: ​Documentation

  • Use keypair that you created

• • Save the public IP address of the instance in it’s return JSON object
