I need to reduce the retry count for unavailable/deleted kubernetes cluster using kubernetes-client-python, currently by default it is 3.
WARNING Retrying (Retry(total=2, connect=None, read=None, redirect=None, status=None)) after connection broken by 'NewConnectionError('<urllib3.connection.VerifiedHTTPSConnection object at 0x00000000096E3860>: Failed to establish a new connection: [Errno 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond',)': /api/v1/pods
WARNING Retrying (Retry(total=1,....... /api/v1/pods
WARNING Retrying (Retry(total=0,....... /api/v1/podsAfter 3 retries it throws an exception.
Is there any way to reduce the count.
Example Code
from kubernetes import client, config
config.load_kube_config(config_file='location-for-kube-config')
v1 = client.CoreV1Api()
ret = v1.list_pod_for_all_namespaces()
for i in ret.items:
print("%s\t%s\t%s" % (i.status.pod_ip, i.metadata.namespace, i.metadata.name))Sadly it seems that it's not possible because:
Python client use urlib3 PoolManager to make requests as you can see there
https://github.com/kubernetes-client/python/blob/master/kubernetes/client/rest.py#L162
r = self.pool_manager.request(method, url,
body=request_body,
preload_content=_preload_content,
timeout=timeout,
headers=headers)and underhood it uses urlopen with default parameters as you can see there
https://urllib3.readthedocs.io/en/1.2.1/pools.html#urllib3.connectionpool.HTTPConnectionPool.urlopen
urlopen(..., retries=3, ...)
so there is now way to pass other value here - you must fork official lib to achieve that.
