I found this runs very long time now. The reason this that reserved offers has many different options (up front, different durations) for each instance. Now there is another api "describe-instance-type-offerings". I changed
raw=$(aws ec2 describe-reserved-instances-offerings --filters "Name=availability-zone,Values=$az" --region $region)
instance_types=$(echo $raw | jq '.ReservedInstancesOfferings[] | .InstanceType' | sort -u)
To
raw=$(aws ec2 describe-instance-type-offerings --filters "Name=location,Values=$az" --location-type availability-zone --region $region)
instance_types=$(echo $raw | jq '.InstanceTypeOfferings[] | .InstanceType' | sort -u
And it completed in around 1 minutes.
Awesome, thanks so much for providing that updated information!
the describe-instance-type-offerings API requires an updated aws cli installation.
