A code management tool known that helps in managing environment configurations related to different kind of environments that we can configure in Puppet such as development, testing, and production. This helps in storing environment-related configuration in the source code repository. Using the source control repo branches, r10k creates (install and update) environments on Puppet Server machine using modules present in local / repository.

/opt/puppetlabs/puppet/bin/gem install r10k

Create file /etc/puppetlabs/r10k/r10k.yaml

:cachedir: '/var/puppet/r10k/cache'
:sources:
  :code:
   remote: 'https://git.fligno.com/reth.bagares/puppet-test.git'
   basedir: '/etc/puppetlabs/code/environments'

remote - control repo

basedir - control repo destination

/opt/puppetlabs/puppet/bin/r10k deploy environment production --verbose --puppetfile

Where production is a branch for control repo to be deployed as an environment

Change directory to {basedir}/{branch}, e.g /etc/puppetlabs/code/environments/production

/opt/puppetlabs/puppet/bin/r10k puppetfile install

Access Puppet Agent

/opt/puppetlabs/bin/puppet agent --test
