[olevole]

I try to use a simple configuration:

  class {'kubernetes':
    controller => true,
  }

got:

Error: Could not retrieve catalog from remote server: Error 500 on SERVER: Server Error: Evaluation Error: Error while evaluating a Resource Statement, Class[Kubernetes]:

Expected Behavior

Expected k8s controller

Steps to Reproduce

Steps to reproduce the behavior:

1. Install clean CentOS ( CentOS Linux release 7.7.1908 (Core) )
2. Install kubernetes/docker puppet module
3. Add to manifest:

class { 'docker':
    dns => '8.8.8.8',
    ip_forward      => true,
    iptables        => true,
    ip_masq         => true,
}
class {'kubernetes':
    controller => true,
}

4. apply config (puppet apply, puppet agent -t)

Environment

• puppetlabs-kubernetes 5.0.0.
• CentOS Linux release 7.7.1908 (Core)

Hi @olevole, to use the puppetlabs-kubernetes module those parameters need to be provided in the configuration. You can use the kubetool docker image to generate a basic configuration if you want to test it out.
