Question

我想使用K8s的python客户端并删除一些资源，例如statefulset。我可以删除有状态集本身，但Ks8不会删除正在运行的Pod。我发现一些示例，他们在删除选项中设置了propagation_policy="Foreground"并完成了工作，但问题出在kubernetes客户端> 9.0，他们更改了API，当我传递delete_options时，它返回此错误：

TypeError: delete_namespaced_stateful_set() takes 3 positional arguments but 4 were given

我试图找到正确的方法来设置删除的传播策略，但是它没有用，并且运行中的Pod没有被杀死，如何在一个api调用中删除所有运行中的Pod和statefuleset？

我当前仅删除状态集的代码：

api_response = k8s_api.delete_namespaced_stateful_set(statefulset_name,namespace)

产生上述错误的代码：

delete_options = client.V1DeleteOptions(propagation_policy="Foreground", grace_period_seconds=5)
api_response = k8s_api.delete_namespaced_stateful_set(statefulset_name,namespace,delete_options)

阅读source code之后：

def delete_namespaced_stateful_set(self, name, namespace, **kwargs):
    """
    delete a StatefulSet
    This method makes a synchronous HTTP request by default. To make an
    asynchronous HTTP request, please pass async_req=True
    >>> thread = api.delete_namespaced_stateful_set(name, namespace, async_req=True)
    >>> result = thread.get()
    :param async_req bool
    :param str name: name of the StatefulSet (required)
    :param str namespace: object name and auth scope, such as for teams and projects (required)
    :param str pretty: If 'true', then the output is pretty printed.
    :param V1DeleteOptions body:
    :param str dry_run: When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
    :param int grace_period_seconds: The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
    :param bool orphan_dependents: Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the \"orphan\" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
    :param str propagation_policy: Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
    :return: V1Status
             If the method is called asynchronously,
             returns the request thread.
    """

我相信设置额外参数（**kwargs）的正确方法是使用key=value格式，而且 V1DeleteOptions 也不是有效的参数，因此不要传递{{ 1}}作为参数，您应该传递 V1DeleteOptions 的每个选项，例如delete_options和propagation_policy="Foreground"：

grace_period_seconds=5

但是，有一种方法可以传递整个 V1DeleteOptions 对象。您可以先将其转换为字典，然后再将其解压缩：

api_response = k8s_api.delete_namespaced_stateful_set(statefulset_name,namespace,propagation_policy="Foreground", grace_period_seconds=5)
