Puppet kubernetes How do I describe a Kubernetes Pod in Puppet DSL

Question

I am using puppetlabs/kubernetes module to configure my kubernetes cluster using puppet. I'm stuck as to how do I describe my pod in puppet DSL. Please help!

Answer 1

The Puppet Kubernetes module currently assumes you already have a Kubernetes cluster up and running. Its focus is on managing the resources in Kubernetes, like Pods, Replication Controllers and Services, not (yet) on managing the underlying kubelet or etcd services. Here’s a quick snippet of code describing a Pod in Puppet’s DSL.

kubernetes_pod { 'sample-pod':
  ensure => present,
  metadata => {
    namespace => 'default',
  },
  spec => {
    containers => [{
      name => 'container-name',
      image => 'nginx',
    }]
  },

Running the above code, assuming we save it as pod.pp, is as simple as:

puppet apply pod.pp
