Puppet 4
and Beyond
Puppet 4
All-in-one agent Path changes URL changes Puppet language
All-in-one agent
puppet-agent package • puppet • facter • native facter •
hiera • mcollective • ruby • … and dependencies
puppet-agent versioning • Not tied directly to puppet versions •
E.g. version 1.0.0 will include: • puppet 4.0.0 • facter 2.4.0 • ruby 2.1.5 • … • Component bumps major: puppet-agent bumps major
Why all-in-one? One package: easier on-ramp for new users Everyone
benefits from latest ruby Reduces the test matrix, reduces support questions Open source puppet and PE use the same package
Path changes
Top-level directory name changes /etc/puppetlabs ~/.puppetlabs
Separate code and config /etc/puppetlabs/agent/code manifests modules environments hieradata hiera.yaml
/etc/puppetlabs/agent/config puppet.conf device.conf …
URL changes
Versioned and Namespaced URLs Puppet 3: /production/catalog/my_node /production/certificate/my_node Puppet 4:
/puppet/v3/catalog/my_node?environment=production /puppet-ca/v1/certificate/my_node?environment=production
Compatibility Puppet 4 is not backwards compatible on the network
with Puppet 3. puppet-server 2.0.0 package depends on puppet-agent 1.0.0 package.

The sad story of nagios
