The bootstrap process
In order to prepare a new node for Puppet management using the demo repo, we need to do a number of things:
- Install Puppet
- Clone the Git repo
- Run Puppet for the first time
In Chapter 3, Managing your Puppet code with Git, we performed these steps manually, but the demo repo automates this process (usually known as bootstrap). Here is the bootstrap script (scripts/bootstrap.sh):
#!/bin/bash
PUPPET_REPO=$1
HOSTNAME=$2
BRANCH=$3
if [ "$#" -ne 3 ]; then
echo "Usage: $0 PUPPET_REPO HOSTNAME BRANCH"
exit 1
fi
hostname ${HOSTNAME}
echo ${HOSTNAME} >/etc/hostname
source /etc/lsb-release
apt-key adv --fetch-keys http://apt.puppetlabs.com/DEB-GPG-KEY-puppet
wget http://apt.puppetlabs.com/puppetlabs-release-${DISTRIB_CODENAME}.deb
dpkg -i puppetlabs-release-${DISTRIB_CODENAME}.deb
apt-get update
apt-get -y install git puppet-agent
cd /etc/puppetlabs/code/environments
mv production production.orig
git clone ${PUPPET_REPO} production
cd production
git checkout...
