AWS CLI Contd

• Creating EC2 instance using AWS CLI.
• To create an ec2 instance we have the command run-instances Refer Here
• Ubuntu EC2 instance
  • Make a note of AMI id of ubuntu 20 => ami-03d5c68bab01f3496
  • Make a note of instance type => t2.micro
  • Make a note of security group name and id => (sg-0eb0f3fca6c9a45a8 openall)
  • Make a note of key pair => ansible
• Lets try to create ubuntu ec2 instance

aws ec2 run-instances --image-id 'ami-03d5c68bab01f3496' \
    --instance-type 't2.micro' --key-name 'ansible' \
    --security-group-ids 'sg-0eb0f3fca6c9a45a8' 

• Lets try to stop the instance

aws ec2 stop-instances --instance-ids i-05025418f5dbd5d9e

• Now lets try to terminate the ec2 instance

aws ec2 terminate-instances --instance-ids i-05025418f5dbd5d9e

Exercise using AWS CLI

1. Create two ubuntu ec2 instances with t2.micro instance type
   1. Try login in to both instances and install any software such as apache or nginx

   sudo apt update
   sudo apt install apache2 -y
   

   2. Stop one ec2 instance and modify the instance type to t2.nano
   3. Terminate all the two ec2 instances

    aws ec2 run-instances --image-id 'ami-03d5c68bab01f3496'     --instance-type 't2.micro' --key-name 'ansible'     --security-group-ids 'sg-0eb0f3fca6c9a45a8'     --count 2 
    aws ec2 describe-instances --filter 'Name=instance-state-name, Values=running'
    aws ec2 stop-instances --instance-ids i-051287cbe1819817f
    aws ec2 describe-instances --filter 'Name=instance-state-name, Values=running'
     aws ec2 stop-instances --instance-ids i-0c8d896941e95dea2
     aws ec2 modify-instance-attribute --instance-id i-0c8d896941e95dea2 --instance-type "{\"Value\": \"t2.micro\"}"
     aws ec2 start-instances --instance-ids i-0c8d896941e95dea2
     aws ec2 describe-instance --instance-id i-0c8d896941e95dea2
    aws ec2 describe-instances --instance-id i-0c8d896941e95dea2
     aws ec2 stop-instances --instance-ids i-0c8d896941e95dea2
     aws ec2 modify-instance-attribute --instance-id i-0c8d896941e95dea2 --instance-type "{\"Value\": \"t2.nano\"}"
    aws ec2 terminate-instances --instance-ids i-0c8d896941e95dea2
     aws ec2 terminate-instances --instance-ids i-051287cbe1819817f

2. Create one windows ec2 instance with t2.mico.
   1. Login into windows ec2 instance and install IIS Server.
   2. Launch Powershell as admin and execute Install-WindowsFeature -name Web-Server -IncludeManagementTools
