Because OpSec systems need love too...

To puppetize a new EC2 instance, run the following commands:

Centos packages:

sudo yum -y install epel-release && sudo yum -y install puppet

Ubuntu packages:

sudo apt-get update && sudo apt-get -y install puppet && sudo puppet agent --enable

Set the hostname of the instances:

sudo echo "myhostname" > /etc/hostname
sudo echo "1.2.3.4 myhostname.mysubdomain myhostname" >> /etc/hosts
sudo hostname -F /etc/hostname

Bootstrap puppet:

sudo puppet agent --server puppet.use1.opsec.mozilla.com --onetime --no-daemonize --verbose

A cronjob that runs puppet every 30 minutes will be created in /var/spool/cron/root.

Clone this repository and all its submodules with:

git clone --recursive git@github.com:mozilla/opsec-puppet.git

Work in progress must go into the dev branch. The puppetmaster pull the dev branch every minute into the dev environment. You can then run puppet agent against the dev environment from your node as follow:

puppet agent --test --environment=dev

Once happy with your changes, submit a pull request against the master branch. The master branch is made available as the production (default) environment.

In the node definition in manifests/site.pp, set the $pin_puppet_env to dev:

node /observer-retriever\d+.use1.opsec.mozilla.com/ {
    $pin_puppet_env = "dev"
    include observer::retriever
}

And run puppet agent --test --environment=dev to set the pin. To reset the environment to production, simply unset the pining in site.pp.

When including third party modules, it is preferred to insert them as submodules. A submodule can be added with the following command:

** /!\ Note: Only use HTTPS links when adding submodules /!\ **

git submodule add https://github.com/maestrodev/puppet-wget.git modules/wget

You can pull the latest version of a submodule by calling git pull from the submodule directory, or from the root for all submodules with:

git submodule foreach git pull origin master

To remove a submodule, do the following:

git submodule deinit modules/mymodule
git rm --cached modules/mymodule
rm -rf .git/modules/modules/mymodule
git commit -m "removed mymodule" .gitmodules
