Bootstrapping in CloudFormation with Autoscale
- by PapelPincel
My CloudFormation template creates an autoscale group and bootstrap it with utility script /opt/aws/bin/cfn-init. When I remove the bootstrap part out of my template the, autoscale get created without any problem, but I add it the CloudFormation Stack fails and add line in /var/log/cloud-init.log :
Error: AutoScalingGroupName does not specify any metadata
The line above appens right after the following command :
/opt/aws/bin/cfn-init --verbose --configsets orderedConfig --region us-east-1 --stack AS15 --resource AutoScalingGroupName --access-key XXXXXXXXXXXXX --secret-key XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
Digging a little bit deeper, in cfn-init I added the following lines the point where it exit:
from pprint import pprint
pprint(vars(detail))
and I get the following trace when running the previous cfn-init command :
{'_description': None,
'_lastUpdated': datetime.datetime(2012, 7, 12, 14, 52, 42),
'_logicalResourceId': u'AutoScalingGroupName',
'_metadata': None,
'_physicalResourceId': u'AS15-AutoScalingGroupName-HNPOXXXXXXXX',
'_resourceStatus': u'CREATE_COMPLETE',
'_resourceStatusReason': None,
'_resourceType': u'AWS::AutoScaling::AutoScalingGroup',
'_stackId': u'arn:aws:cloudformation:us-east-1:XXXXXXXXXXXXX:stack/AS15/XXXXXXXX-cc30-11e1-XXXXXX-XXXXXXXXXX',
'_stackName': u'AS15'}
As you can see, the metadata field is empty and that's the reason why it fails to create the stack.
Is there any known side effects for cfn-init when used with autoscale ?
