How to create an EC2 instance with AWS CLI

1. Install aws CLI on your working station (Linux or Windows)

$aws configure 
AWS Access Key ID [****************GYFA]:
AWS Secret Access Key [****************DTIn]:
Default region name [us-east-1]:
Default output format [None]:
Available Tools

2. Create a key with following commnad

#aws ec2 create-key-pair --key-name ovi-key --query 'KeyMaterial' --output text > ovi-key.pem

3. Create an instance

#aws ec2 run-instances --image-id ami-6869aa05 --count 1 --instance-type t2.small --key-name ovi-key --security-group-ids sg-74ef3210 --subnet-id subnet-01ac3976 --associate-public-ip-address
