AWS CLI EC2 Instance Status

How to display AWS EC2 instance statuses.

aws ec2 describe-instance-status \
--query 'InstanceStatuses[].[InstanceId,SystemStatus.Status]' \
--include-all-instances \
--region us-east-2
--profile abcdef \

Query and Filter.

aws ec2 describe-instance-status \
--query 'InstanceStatuses[].[InstanceId,SystemStatus.Status]' \
--filter 'Name=instance-state-name,Values=stopped' \
--region us-east-2
--profile abcdef \

Filter event.code equal to instance-reboot.

aws ec2 describe-instance-status \
--query 'InstanceStatuses[].[InstanceId,SystemStatus.Status]' \
--filter 'Name=eventcode,Values=instance-reboot' \
--region us-east-2
--profile abcdef \

AWS CLI: Describe Instances

If you have a ton of EC2 instances, one way to get results quickly is to run to use AWS CLI such as “describe-instances.” Here’s an example on how to get a list of instances with a tag name equal to some value. In addition, you limit the display only results you want displayed.

$ aws ec2 describe-instances \
--query 'Reservations[].Instances[].Tags[?Key==`Name`].Value' \
--filter Name=tag:Project,Values=web \
--region us-east-1 \
--profile default \
--output text

This returns values of the “Name” tag name in instances where they occur.
