AWS Cloud formation cfn-init error

Question

I'm trying to create cluster structure using Cloud Formation script. I'm using Bitnami drupal AMI. Bu the script produces below eror:

WaitCondition received failed message: 'Failed to run cfn-init' for uniqueId: i-4d121a16

Then I connected to instance and checked cfn-init.log:

bitnami@ip-10-58-51-235:/var/log$ cat cfn-init.log                              
2013-01-01 19:18:23,128 [INFO] Starting new HTTP connection (1): 169.254.169.254

2013-01-01 22:52:17,621 [INFO] Starting new HTTPS connection (1): cloudformation-waitcondition-    eu-west-1.s3.amazonaws.com

My AWS Console events like below:

Logical ID PhysicalID Status Reason

mycluster arn:aws:cloudformation:eu-west-1:318730... CREATE_FAILED The following resource(s) failed to create: [WaitCondition]

WaitCondition vgdrobe-WaitCondition-UWEKNUJ8TMT6 CREATE_FAILED WaitCondition received failed message: 'Failed to run cfn-init' for uniqueId: i-59272f1c

WaitCondition vgdrb-WaitCondition-MML6Y6E47WTB CREATE_IN_PROGRESS

WebServerGroup vgdrb-WebServerGroup-1OBJYOSQX8093 CREATE_COMPLETE

I couln't find the problem. Could you help me please?

Kind regards...

Answer 1

Is it possible that the cfn-init scripts are not part of the image?

According to the docs , they're installed as part of the Amazon Linux image, but may not be included by default in other images.

Answer 2

Expanding on what Chris suggested, I had to add the following to get cfn-init working on my CloudFormation script:

"apt-get -y install python-setuptools\n", 
"easy_install https://s3.amazonaws.com/cloudformation-examples/aws-cfn-bootstrap-1.0.tar.gz\n", 

I found some really useful info about this here: http://smart421.wordpress.com/2012/12/14/aws-cloudformation-and-chef-on-centos/

I also found errors in my UserData caused cfn-init to fail. I got around this by using VS2012 to validate the script before uploading it (as suggested here: How can I quickly and effectively debug CloudFormation templates? ).

Hope that helps.
