AWS EC2 CLI

The AWS Command Line Interface (AWS CLI) is a unified tool to manage your AWS services. With just one tool to download and configure, you can control multiple AWS services from the command line and automate them through scripts.

If you haven't installed AWS CLI yet start Installing the AWS CLI Guide from Amazon. 

AWS EC2

Amazon Elastic Compute Cloud (Amazon EC2) provides secure and resizable computing capacity in the Amazon Web Services Cloud. Using Amazon EC2 eliminates the need to invest in hardware up front, so you can develop and deploy applications faster. Amazon Virtual Private Cloud (Amazon VPC) enables you to provision a logically isolated section of the Amazon Web Services Cloud where you can launch Amazon Web Services resources in a virtual network that you've defined.

AWS CLI options and list all the services. If you need to see what all the available commands for AWS EC2 specifically, you would type 'aws ec2 help.' It will become a huge aid to you in becoming an AWS CLI pro.

List Instance ID

aws ec2 describe-instances --region regionname --preofile profilename --instances-ids instancename 

List Instances with public IP addresses and Name

aws ec2 describe-instances --query 'Reservations[*].Instances[?not_null(PublicIpAddress)]' | jq -r '.[][]|.PublicIpAddress+" "+(.Tags[]|select(.Key=="Name").Value)' 

List VPCs and CIDR IP Block

aws ec2 describe-vpcs | jq -r '.Vpcs[]|.VpcId+" "+(.Tags[]|select(.Key=="Name").Value)+" "+.CidrBlock'

List Subnets for a VPC

aws ec2 describe-subnets --filter Name=vpc-id,Values=vpc-0d1c1cf4e980ac593 | jq -r '.Subnets[]|.SubnetId+" "+.CidrBlock+" "+(.Tags[]|select(.Key=="Name").Value)'

List Security Groups

aws ec2 describe-security-groups | jq -r '.SecurityGroups[]|.GroupId+" "+.GroupName'

 Add Rule to Security Group

aws ec2 authorize-security-group-ingress --group-id sg-02a63c67684d8deed --protocol tcp --port 443 --cidr 35.0.0.1

 Delete Rule from Security Group

aws ec2 revoke-security-group-ingress --group-id sg-02a63c67684d8deed --protocol tcp --port 443 --cidr 35.0.0.1

 Edit Rules of Security Group

aws ec2 update-security-group-rule-descriptions-ingress --group-id sg-02a63c67684d8deed --ip-permissions 'ToPort=443,IpProtocol=tcp,IpRanges=[{CidrIp=202.171.186.133/32,Description=Home}]'

 Delete Security Group

aws ec2 delete-security-group --group-id sg-02a63c67684d8deed

 

Describe all instances Name, PublicIP, status, and type.

 aws ec2 describe-instances --profile qa --query "Reservations[*].Instances[*].{PublicIP:PublicIpAddress,Type:InstanceType,Name:Tags[?Key=='Name']|[0].Value,Status:State.Name}"  --filters "Name=instance-state-name,Values=running" "Name=tag:Name,Values='*'"  --output table

Describe all instances Name, PublicIP, status, and type and VpcId.

aws ec2 describe-instances --query "Reservations[*].Instances[*].{PublicIP:PublicIpAddress,PrivateIP:PrivateIpAddress,Name:Tags[?Key=='Name']|[0].Value,Type:InstanceType,Status:State.Name,VpcId:VpcId}" --filters Name=instance-state-name,Values=running --output table
