<p>We are on Kubernetes 1.9.0 and wonder if there is way to access an "ordinal index" of a pod with in its statefulset configuration file. We like to dynamically assign a value (that's derived from the ordinal index) to the pod's label and later use it for setting pod affinity (or antiaffinity) under spec.</p>

<p>Alternatively, is the pod's instance name available with in statefulset configfile? If so, we can hopefully extract ordinal index from it and dynamically assign to a label (for later use for affinity).</p>

<p>You could essentially get the unique name of your pod in statefulset as an environment variable, you have to extract the ordinal index from it though</p>

<p>In container's spec:</p>

<pre><code>env:
  - name: cluster.name
    value: k8s-logs
  - name: node.name
    valueFrom:
      fieldRef:
        fieldPath: metadata.name
</code></pre>
