Defined Type: kerberos::exec

Overview

Define kerberos::exec

In order to make puppet execs work with a Kerberized cluster we found out that the easiest solution is to execute a wrapper that just runs kinit before executing any command that needs authentication.

Parameters:

  • command (Any)
  • user (Any)
  • logoutput (Any) (defaults to: undef)
  • timeout (Any) (defaults to: undef)
  • unless (Any) (defaults to: undef)
  • creates (Any) (defaults to: undef)
  • refreshonly (Any) (defaults to: undef)
  • path (Any) (defaults to: undef)
