Puppet Enterprise 2017.3

These are the known issues for Puppet Server in this PE release.

File sync error causes pe-puppetserver service to shut down due to incorrect pe-puppet owner and group permissions

During an r10k deployment, if the pe-puppet user does not have permissions to delete files in the environment directory, a file sync error causes the pe-puppetserver service to shut down during deployment.

This issue can be fixed by setting permissions in the environment directory to owner pe-puppet and group pe-puppet with the command: chown -R pe-puppet:pe-puppet /etc/puppetlabs/code/environments.

Installing gems when Puppet Server is behind a proxy requires manual download of gems

If you run Puppet Server behind a proxy, the puppetserver gem install command fails. Instead you can install the gems as follows:

  1. Use rubygems.org to search for and download the gem you want to install, and then transfer that gem to your master.
  2. Run /opt/puppetlabs/bin/puppetserver gem install --local <PATH TO GEM>.

Puppet Server run issue when /tmp/ directory mounted noexec

In some cases, especially for RHEL 7 installations, if the /tmp directory is mounted as noexec, Puppet Server might fail to run correctly, and you might see an error in logs similar like:

Nov 12 17:46:12 fqdn.com java[56495]: Failed to load feature test for posix: can't find user for 0
Nov 12 17:46:12 fqdn.com java[56495]: Cannot run on Microsoft Windows without the win32-process, win32-dir and win32-service gems: Win32API only supported on win32
Nov 12 17:46:12 fqdn.com java[56495]: Puppet::Error: Cannot determine basic system flavour

To work around this issue, you can either mount the /tmp directory without noexec, or you can choose a different directory to use as the temporary directory for the Puppet Server process.

If you want to use a directory other than /tmp, you can add an extra argument to the $java_args parameter of the puppet_enterprise::profile::master class using the console, for example, add {"Djava.io.tmpdir=/var/tmp":""} as the value for the $java_args parameter.

JAVA_ARGS in /etc/default/pe-puppetserver should have the same value as before.

Whether you use /tmp or a different directory, you must set the permissions of the directory to 1777. This allows the Puppet Server JRuby process to write a file to /tmp and then execute it.

HTTPS client issues with newer Apache mod_ssl servers

When configuring Puppet Server to use a report processor that involves HTTPS requests, you might encounter compatibility issues between the JVM HTTPS client and certain server HTTPS implementations. This is usually indicated by a Could not generate DH keypair error in the Puppet Server logs. See SERVER-17 for workarounds.
