• List EC2 Instances

    aws ec2 describe-instances
  

• Start an EC2 Instance

    aws ec2 start-instances --instance-ids i-1234567890abcdef0
  

• Stop an EC2 Instance

    aws ec2 stop-instances --instance-ids i-1234567890abcdef0
  

• Reboot an EC2 Instance

    aws ec2 reboot-instances --instance-ids i-1234567890abcdef0

• Delete a Key Pair

    aws ec2 delete-key-pair --key-name MyKeyPair
  

Elastic IP Addresses

• Allocate a New Elastic IP Address

    aws ec2 allocate-address
  

• Associate an Elastic IP Address with an Instance

    aws ec2 associate-address --instance-id i-1234567890abcdef0 --allocation-id eipalloc-12345678
  

• Disassociate an Elastic IP Address

    aws ec2 disassociate-address --association-id eipassoc-12345678

AMIs (Amazon Machine Images)

• Create an AMI from an Instance

    aws ec2 create-image --instance-id i-1234567890abcdef0 --name "My server" --no-reboot
  

• List AMIs

    aws ec2 describe-images --owners self
  

• Deregister an AMI

    aws ec2 deregister-image --image-id ami-0abcdef1234567890
  

Volumes

• Create a New Volume

    aws ec2 create-volume --size 10 --region us-west-2 --availability-zone us-west-2a --volume-type gp2
  

• Attach a Volume to an Instance

    aws ec2 attach-volume --volume-id vol-12345678 --instance-id i-1234567890abcdef0 --device /dev/sdf
