I can use the following to list all Amazon Windows EC2 instances. How do I list Linux instances?
aws ec2 describe-images --owners self amazon --filters "Name=root-device-type,Values=ebs" "Name=platform,Values!=windows"
I think you can use the below to list all instances with platform type, then filter by platform type.
for region in `aws ec2 describe-regions --output text | cut -f2|awk -F. '{print $2}'`; do echo -e "\nInstances in: '$region':"; aws ec2 describe-instances --query 'Reservations[*].Instances[*].[InstanceId,Platform]' --output text --region $region; done;
Platform type "None" indicates the Linux.

How to filter out AllocationId for Elastic IP address in AWS cli 2.0 in Powershell.
aws ec2 describe-addresses --query 'Addresses[?AssociationId!=`null`].{AllocId:AllocationId} | [0]' --output text --region ap-southeast-2 --filters "Name=tag:xxx,Values=xxx"
tried this, returns Null. Need help especially with TAG filter.
I am trying to automate the process of EIP allocation to my newly generated Instance from autoscaling group.
Try this as it working for me, I just reorder the command query after filter.
aws ec2 describe-addresses --region ap-southeast-2 --filters "Name=tag:Name,Values=xxx" --query 'Addresses[?AssociationId!=`null`] | [0]' --output table
This command lists hundreds of windows servers. How do I select the most popular ones those are displayed on web console while I create a new instance?

I am looking for the full name and not just the ami-id.
For e.g. which one of the above is "ami-04ca2d0801450d495"?
The DescribeImages API call returns the name of the AMI along with the rest of the info. To extract just the name of the AMI, you can run the following command:
aws ec2 describe-images --image-ids $IMAGE_ID \
--output text --query 'Images[*].Name'
Details about the describe-images command can be found here.
This command will return the full name of the given ami ID
aws ssm get-parameters-by-path --path "/aws/service/ami-windows-latest" --region us-east-1 | grep -C3 '04ca2d0801450d495'
I want to list the VPC id's which have a particular tag (Name=MyVPC).
I am aware that I can use --filter and run:
aws ec2 describe-vpcs --filters Name=tag:Name,Values=MyVPC --query 'Vpcs[].VpcId'
This works completely fine.
Is there a way I can achieve this without using --filter and only use JMESPath?
aws ec2 describe-vpcs --query 'Vpcs[?Tags[?Key==`Name`]|[?Value==`MyVPC`]].VpcId' --output text
Try this command:
aws ec2 describe-vpcs --query 'Vpcs[?contains(Tags[?Key==`Name`].Value[], `MyVPC`) == `true`].[VpcId]' --output text
I want to run aws ec2 describe-instances looking for any instances without a VpcId property (those in ec2-classic)
How can I return ec2-classic instances using either the --query flag or JMESPath expression to get results without a VpcId?
This cli command will list all the instances which doesn't have VpcId.
aws ec2 describe-instances --region us-east-1 --query 'Reservations[*].Instances[?!not_null(VpcId)] | [].[InstanceId]' --output text
You can tweak the same to list all instances which has VpcId.
aws ec2 describe-instances --region us-east-1 --query 'Reservations[*].Instances[?not_null(VpcId)] | [].[InstanceId]' --output text
One approach is to query all instances and look for entries that do not have a SubnetId. The following CLI lists the EC2 classic instances. You can change the --query option to get the attributes you want.
aws ec2 describe-instances --query 'Reservations[].Instances[].[InstanceId, Tags[?Key==`Name`].Value | [0], State.Name, SubnetId]' --output text | grep -v subnet
Output
i-123456789abcdef01 MyClassicRunning running None
i-123456789abcdef23 MyClassicStopped stopped None
Faily new to AWS however I am looking to terminate a set of ec2 instances using the AWS CLI by filtering by a Tag name.
If I use describe-instances, I can filter by tag:key=value . For terminate-instances I don't see a way of filtering. I assume this is possible since I can filter and terminate using the AWS console but I am looking to do this via CLI.
Latest AWS CLI allows you to avoid the need for any scripts or jq:
aws ec2 terminate-instances --instance-ids $(aws ec2 describe-instances --query 'Reservations[].Instances[].InstanceId' --filters "Name=tag:tagkey,Values=tagvalue" --output text)
as long as the number of expected instances is not huge, the above can be used.
The terminate-instances command only takes a list of instance IDs. You would need to write a script to run the describe-instances command first and capture the instance IDs, then pass those IDs to the terminate-instances command.
I created the following script(.sh) and it worked for me:
aws ec2 describe-instances --query 'Reservations[*].Instances[*].[InstanceId]' --filters 'Name=tag-value,Values=MYTAG' --output text |
grep stopped |
awk '{print $2}' |
while read line;
do aws ec2 terminate-instances --instance-ids $line
done
