While there appear to be a few ways to output and filter some AWSCLI commands into this list, does someone have a nice+easy way to list all EC2 instance types for a specific region?

Or perhaps that list is published in a .json file up in a bucket someplace, maintained by AWS?

I'm simply looking for this sort of output:

t1.micro

t2.nano

t2.micro

t2.small

...

Well it seems that at least one programmatic way to do this is to query the AWS Pricing API:

#!/bin/bash



curl https://pricing.us-east-1.amazonaws.com/offers/v1.0/aws/AmazonEC2/current/index.json | jq -r '.products.attributes["instanceType"]' | sort -u | grep '.'

A gist for this is here, in case of future tweaks:

What this is lacking is grouping/specifying by AWS Region, which can be an important distinction -- not every region has all instance type offerings.

As Far As I Know, such list is not available and cannot be queried from aws cli.

Even when running the aws ec2 run-instances, the instance-type parameter lists available instance types and refers to aws docs

Others have parsed the data and made it available.

This is the command you can use to get all instance types in your one region of your account:

$ aws ec2 describe-instances --region us-east-1 --filters "Name=instance- type,Values=*"  --query "Reservations[*].Instances[*].InstanceType" --output text

To sort and count:

$ | sort | uniq -c | sort -nr

Iterate over all regions and print to stdout:

$for region in $(aws ec2 describe-regions --query 'Regions.{Name:RegionName}' --output text); do echo $region && aws ec2 describe-instances --region $region --filters "Name=instance-type,Values=*"  --query "Reservations[*].Instances[*].InstanceType" --output text | sort | uniq -c | sort -nr; done

With output redirection to file /tmp/instances:

$ for region in $(aws ec2 describe-regions --query 'Regions.{Name:RegionName}' --output text); do aws ec2 describe-instances --region $region --filters "Name=instance-type,Values=*" --query "Reservations[*].Instances[*].InstanceType" --output text | sort | uniq -c | sort -nr >> /tmp/instances; done

Sample Output(regions that have no instances will just be printed):

ap-south-1

eu-west-3

eu-west-2

 1 m4.large

eu-west-1

ap-northeast-2

 1 m4.large

ap-northeast-1

 1 m4.large

sa-east-1

ca-central-1

 1 m4.large

ap-southeast-1

ap-southeast-2

eu-central-1

 1 m4.large

us-east-1

As others have pointed out, this is not something you can just get out of an AWS API endpoint.

So to fill this gap, I've built a general module for dealing with this issue.

I hope this helps for a variety of use cases:
