Puppet Cloud Provisioner
Puppet Module to launch and manage Cloud instances.
This module requires Puppet 2.7.2 or later.
Please report any problems you have with the Cloud Provisioner module in the project page issue tracker at:
Getting Started with Amazon EC2
Before launching instances with the Cloud Provisioner module, you'll need to register with Amazon AWS and obtain your access credentials.
Once registered, obtain your Access Key ID and Access Key. Place them into the ~/.fog file with the following syntax:
:default: :aws_access_key_id: AKIAIXXXXXXXXXXXXXXX :aws_secret_access_key: jcjnhaXXXXXXXXXXXXXXXXXXXX/XXXXXXXXXXXXX
Once you have your Access key and ID in the ~/.fog file, you'll also need to generate your SSH private key in the AWS console. The filesystem path to this private key is what you should provide to the --keyfile option.
Finally, you'll probably want to configure the default EC2 security group to allow SSH (Port 22) access. This can be accomplished through the Amazon EC2 console. The install actions will fail if they cannot access the target system on port 22 (SSH).
- guid (>= 0.1.1)
- fog (0.7.2)
Note, the rspec unit tests currently have problems with Fog 0.9.0, but the command line actions themselves appear to work. If you have problems with Cloud Provisioner, please try the specific version of Fog. You may install 0.7.2 using the following command:
gem install fog -v 0.7.2 --no-ri --no-rdoc
Picking an AMI image can be daunting. There are a lot of them out there.
During development of Cloud Provisioner, I often used the following CentOS image which is compatible with [AWS Free Usage Tier][free tier] amazon instances:
- ami-2342a94a (US-East region) CentOS 5 (Login: root)
- ami-25df8e60 (US-West region) CentOS 5 (Login: root)
NOTE: These CentOS AMI's are from rightscale and are configured to use their YUM and GEM mirrors. As a result, they often contain out of date software libraries.
A Ubuntu based AMI in the East region also works well with the [AWS Free Usage Tier][free tier] Amazon instances:
- ami-06ad526f (US-East region) Ubuntu (Login: ubuntu)
Launching EC2 Instances
With your EC2 credentials placed in ~/.fog and your SSH private key available on your system, you may launch a new instance with this module installed using the following single command:
$ puppet node create --image ami-2342a94a --keypair jeff --type t1.micro notice: Creating new instance ... notice: Creating new instance ... Done notice: Creating tags for instance ... notice: Creating tags for instance ... Done notice: Launching server i-e5c00f84 ... ############## notice: Server i-e5c00f84 is now launched notice: Server i-e5c00f84 public dns name: ec2-107-20-18-142.compute-1.amazonaws.com ec2-107-20-18-142.compute-1.amazonaws.com
Once launched, you should be able to SSH to the new system using the private key associated with the keypair specified in the create action:
$ ssh -i ~/.ssh/jeff.pem firstname.lastname@example.org RSA key fingerprint is a1:88:33:fa:de:d7:7c:a8:84:ae:89:73:01:a2:2b:e8. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added 'ec2-107-20-18-142.compute-1.amazonaws.com,22.214.171.124' (RSA) to the list of known hosts. [root@domU-12-31-39-07-8C-79 ~]# quit
Finally, you're able to install Puppet or Puppet Enterprise on the newly launched system:
$ puppet node install --login root --keyfile ~/.ssh/jeff.pem ec2-107-20-18-142.compute-1.amazonaws.com notice: Waiting for SSH response ... notice: Waiting for SSH response ... Done notice: Installing Puppet ... 66421292-9dee-7f41-624e-6ad2c50d78c1
If you need more detailed information, please use the --verbose and --debug options to get more detailed output from the command.
As we can see, this installs Puppet using ruby gems:
$ ssh email@example.com puppet --version 2.6.4
The following installation scripts are available to install puppet on a target system. These script are appropriate values for the --install-script option to the puppet node install action.
gems (default) - Installs Puppet and Facter from RubyGems.
puppet-enterprise - Installs Puppet by uploading a copy of the puppet enterpise tarball from your workstation to the target node along with an automated answers file.
puppet-enterprise-s3 - Installs Puppet by downloading a copy of Puppet Enterprise 1.1 from Puppet Labs. This may be much faster than the puppet-enterprise script if you have limited upload bandwidth.
