To see the available instance types in a specific Region
The available instance types vary by Region. To see if an instance type is
available in a Region, use the describe-instance-types-offerings--region
parameter. Include the --filters
parameter to scope the results to the instance family or instance type that
you're interested in and the --query
parameter to scope the output
to the value of InstanceType
.
aws ec2 describe-instance-type-offerings \ --region
us-east-2
\ --filters 'Name=instance-type, Values=trn1*
' \ --query 'InstanceTypeOfferings[].InstanceType'
Expected output
[
"trn1.2xlarge",
"trn1.32xlarge",
"trn1n.32xlarge"
]
Instance state
Instances must be in the running
state. You can’t get instance
topology information for instances that are in another state.
IAM permission
Your IAM identity (user, user group, or role) requires the following IAM permission:
-
