Cloudformation with Ubuntu throwing errors
- by Sammaye
I have been doing some reading and have come to the understanding that if you wish to use a launchConfig with Ubuntu you will need to install the cfn-init file yourself which I have done:
"Properties" : {
"KeyName" : { "Ref" : "KeyName" },
"SpotPrice" : "0.05",
"ImageId" : { "Fn::FindInMap" : [ "AWSRegionArch2AMI", { "Ref" : "AWS::Region" },
{ "Fn::FindInMap" : [ "AWSInstanceType2Arch", { "Ref" : "InstanceType" },
"Arch" ] } ] },
"SecurityGroups" : [ { "Ref" : "InstanceSecurityGroup" } ],
"InstanceType" : { "Ref" : "InstanceType" },
"UserData" : { "Fn::Base64" : { "Fn::Join" : ["", [
"#!/bin/bash\n",
"apt-get -y install python-setuptools\n",
"easy_install https://s3.amazonaws.com/cloudformation-examples/aws-cfn-bootstrap-1.0-6.tar.gz\n",
"cfn-init ",
" --stack ", { "Ref" : "AWS::StackName" },
" --resource LaunchConfig ",
" --configset ALL",
" --access-key ", { "Ref" : "WorkerKeys" },
" --secret-key ", {"Fn::GetAtt": ["WorkerKeys", "SecretAccessKey"]},
" --region ", { "Ref" : "AWS::Region" }, " || error_exit 'Failed to run cfn-init'\n"
]]}}
But I have a problem with this setup that I cannot seem to get a decent answer to. I keep getting this error in the logs:

I have absolutely no idea what scripts-user means and Google is not helping much here either. I can, when I ssh into the server, see that it runs the userdata script since I can access cfn-init as a command whereas I cannot in the original AMI the instance is made from.
However I have a launchConfig:
"Comment" : "Install a simple PHP application",
"AWS::CloudFormation::Init" : {
"configSets" : {
"ALL" : ["WorkerRole"]
},
"WorkerRole" : {
"files" : {
"/etc/cron.d/worker.cron" : {
"content" : "*/1 * * * * ubuntu /home/ubuntu/worker_cron.php &> /home/ubuntu/worker.log\n",
"mode" : "000644",
"owner" : "root",
"group" : "root"
},
"/home/ubuntu/worker_cron.php" : {
"content" : { "Fn::Join" : ["", [
"#!/usr/bin/env php",
"<?php",
"define('ROOT', dirname(__FILE__));",
"const AWS_KEY = \"", { "Ref" : "WorkerKeys" }, "\";",
"const AWS_SECRET = \"", { "Fn::GetAtt": ["WorkerKeys", "SecretAccessKey"]}, "\";",
"const QUEUE = \"", { "Ref" : "InputQueue" }, "\";",
"exec('git clone x '.ROOT.'/worker');",
"if(!file_exists(ROOT.'/worker/worker_despatcher.php')){",
"echo 'git not downloaded right';",
"exit();",
"}",
"echo 'git downloaded';",
"include_once ROOT.'/worker/worker_despatcher.php';"
]]},
"mode" : "000755",
"owner" : "ubuntu",
"group" : "ubuntu"
}
}
}
}
Which does not seem to run at all. I have checked for the files existance in my home directory and it's not there. I have checked for the cronjob entry and it's not there either. I cannot, after reading through the documentation, seem to see what's potentially wrong with my code.
Any thoughts on why this is not working? Am I missing something blatant?
