Re: Bosh - creating an aws instance - merge two calls into one

Dmitriy Kalinin


we currently have two separate cpi methods for creating vms (create_vm) and
setting metadata on the vms (set_vm_metadata). create_vm call does not
receive necessary metadata to apply tags to the vm at creation time.
potentially such functionality could be added in future. i would recommend
adding an issue to

Hello Every one,

we are currently using bosh version 262.3. The question I have is on how
bosh provisions ec2 instances in AWS through bosh-aws-cpi.

To give a little context on how provisioning on AWS used to happen

In March, AWS Blog announced two new features we’re implementing:
Ability to enforce required tags on RunInstances with IAM policy
Ability to include tags on RunInstances with API and CLI

Which means, before this date all provisioning was done in two steps:

ec2 run-instances --image-id <ami-id> --count 1 --instance-type t2.micro
--subnet-id <subnet-id>

ec2-create-tags <instanceid> --tag "Name=<name_value>" --tag
"App=<app_value>" --tag "AppOwner=<app_owner_value>" --tag

The new workflow assured that instance creation and tag management can be
done in a single call.

ec2 run-instances --image-id <ami-id> --count 1 --instance-type t2.micro
--subnet-id <subnet-id> --tag-specifications 'ResourceType=instance,Tags=[{

Bosh ( tested with version 262.3 ) still seem to be provisioning instances
in multiple calls instead of a single one. Bosh is issuing 1 api call just
to create the instance, and then following that up with a 2nd api call to

Does anyone know if this is addressed in newer versions of bosh ? I looked
at the code but did not seem like it and am not sure if this can be easily
done ? any thoughts ?
