<p>I want to use the python client of K8s and delete some of the resources such as statefulset. I can delete the statefulset itself but Ks8 doesn't delete the running pods. I found some examples that they set <code>propagation_policy="Foreground"</code> in delete options and that get the job done but the problem is in the kubernetes client > 9.0 they changed the API and when I pass the delete_options it returns this error:</p>

<pre><code>TypeError: delete_namespaced_stateful_set() takes 3 positional arguments but 4 were given
</code></pre>

<p>I tried to find the correct way to set the propagation policy for delete but it didn't work and running pods were not being killed, how I can delete all the running pods and statefuleset in one api call?</p>

<p>My current code that just deletes the statefulset:</p>

<pre><code>api_response = k8s_api.delete_namespaced_stateful_set(statefulset_name,namespace)
</code></pre>

<p>The code that produces above error:</p>

<pre><code>delete_options = client.V1DeleteOptions(propagation_policy="Foreground", grace_period_seconds=5)
api_response = k8s_api.delete_namespaced_stateful_set(statefulset_name,namespace,delete_options)
</code></pre>

<p>After reading the <a href="https://github.com/kubernetes-client/python/blob/master/kubernetes/client/apis/apps_v1beta1_api.py" rel="nofollow noreferrer">source code</a>:</p>

<p>I believe the correct way to set the extra params (<code>**kwargs</code>) is using the <code>key=value</code> format, also <em>V1DeleteOptions</em> is not a valid parameter so instead of passing <code>delete_options</code> as an argument you should pass each option of <em>V1DeleteOptions</em>, such as <code>propagation_policy="Foreground"</code> and <code>grace_period_seconds=5</code>:</p>

<pre><code>api_response = k8s_api.delete_namespaced_stateful_set(statefulset_name,namespace,propagation_policy="Foreground", grace_period_seconds=5)
</code></pre>

<p>There is a way, however, to pass an entire <em>V1DeleteOptions</em> object. You can first convert it to a dict and then unpack it:</p>

<pre><code>delete_options = client.V1DeleteOptions(propagation_policy="Foreground", grace_period_seconds=5)
api_response = k8s_api.delete_namespaced_stateful_set(statefulset_name,namespace,**delete_options.do_dict())
</code></pre>
