BlueHat Tech EC2 instance creation shell script!

This shell script creates EC2 instances and, in addition, during the process performs the following tasks:

• Creates group security with rules
• Create a key pair
• Adds tags on Instance, Group Security and instance volumes
• Read a powershall userdata where it change the hostname and administrator password for Windows 2016 or higher

To choose which region the instance will be created in, run aws configure , and specify the region as shown below:

aws configure
AWS Access Key ID [****************5JKA]:
AWS Secret Access Key [****************WcJ0]:
Default region name [us-east-1]: us-east-2
Default output format [json]: 

See, that I just hit Enter for the first two options, because I already have my AWS connection set up. And I specified us-east-2 as a new region. If you are not yet connected to AWS, search for the aws configure command to see how to establish a connection with AWS.

Notes:

• Before running this shell script, open the code and try to understand what it does. Change it as needed.
• The userdata here is for Windows only.
• If an error appears saying that the SubnetId does not exist, it can be for two reasons: 1- It does not really exist. 2- You can be in the different region of the SubnetId that you specified. Which may be the most common mistake.
• When choosing the option to use the password defined in userdata, wait at least 3 minutes before trying to make an RDP connection.
• If the option of random password with key pair is chosen, in addition to displaying a cryptographic key in the terminal, a file will be created with the content of the key in the same directory as this script, in the following format: hostname-keypair.pem

To use this shell script, enter the following commands:

git clone https://github.com/marceloeliassantos/run-ec2
cd run-ec2
chmod +x run-ec2.sh
./run-ec2.sh
