 $ sudo ./aws/install
 $ sudo aws configure
 # Mac
 $ python3 -m pip install --user awscli

EC2 Commands

# configure AWS - May need to use sudo if installed via sudo 
$ aws configure
# List EC2 instances
$ aws ec2 describe-instances --query 'Reservations[].Instances[].[State.Name, InstanceId, ImageId, InstanceType, PublicIpAddress, SubnetId, VpcId,Tags[?Key==`Name`]| [0].Value]' 
# List Vpcs
$ aws ec2 describe-vpcs
# List Subnets
$ aws ec2 describe-subnets
# List Security Groups
$ aws ec2 describe-security-groups --query "SecurityGroups[*].{Name:GroupName,ID:GroupId}"
$ aws ec2 describe-security-group-rules --filter Name="group-id",Values="sg-1234567890abcdef0"
# Add an inbound rule to security group (cidr range optional)
$ aws ec2 authorize-security-group-ingress \
--group-id sg-1234567890abcdef0 \
--protocol tcp \
--port 22 \
--cidr 203.0.113.0/24
# Manage Ec2 state
$ aws ec2 start-instances --instance-ids i-1234567890abcdef
$ aws ec2 stop-instances --instance-ids i-1234567890abcdef
$ aws ec2 terminate-instances --instance-ids i-1234567890abcdef
# Create an AMI from an instance ID
$ aws ec2 create-image \
--instance-id i-1234567890abcdef0 \
--name "My server" \
