CLI contd …

Lets create an ubuntu 24.04 ec2 instance in mumbai region

• output: ec2 instance with a public ip
• inputs:
  • tags: Name: from-cli
  • ami: ami-00bb6a80f01f03502
  • instance type: t2-micro
  • subnet: subnet-067813a42fb6cbebe
  • key pair: my_idrsa
  • security group: docker
  • region: ap-south-1
• lets find a command to create ec2 instance
• Running on Powershell

aws ec2 run-instances `
    --image-id "ami-00bb6a80f01f03502" `
    --instance-type "t2.micro" `
    --key-name "my_idrsa" `
    --subnet-id "subnet-067813a42fb6cbebe" `
    --tag-specifications "ResourceType=instance,Tags=[{Key=Name,Value=from-cli}]" `
    --associate-public-ip-address `
    --security-group-ids "sg-077690d1b4c7e9836"

• Running on bash

aws ec2 run-instances \
    --image-id "ami-00bb6a80f01f03502" \
    --instance-type "t2.micro" \
    --key-name "my_idrsa" \
    --subnet-id "subnet-067813a42fb6cbebe" \
    --tag-specifications "ResourceType=instance,Tags=[{Key=Name,Value=from-cli}]" \
    --associate-public-ip-address \
    --security-group-ids "sg-077690d1b4c7e9836"

Lets get the ec2 instance id of the machine created above

• Command

aws ec2 describe-instances --query "Reservations[0].Instances[0].InstanceId"

Lets get the names of all key pairs

• Command

aws ec2 describe-key-pairs

Lets get all the security group ids

• Command

aws ec2 describe-security-groups --query "SecurityGroups[].GroupId"

• We have been using JMES Path

Lets get the security id for a security group with name docker

• Command

 aws ec2 describe-security-groups --query "SecurityGroups[?GroupName == 'docker'].GroupId"
