Can't tune maxsize of connection pool used

[yuvipanda]

I get a lot of log messages of the form:

WARNING:urllib3.connectionpool:Connection pool is full, discarding connection: 10.0.0.1

Setting maxsize of HTTPConnectionPool (or equivalent object) to something higher would help with this, and with connection re-use help performance too (I am hoping!). I can't seem to find a way to set this though!

Ideally, it'll be a param to kubernetes.config.configuration that can be tuned.

However, the kubernetes.config.configuration object says it is autogenerated - but am unable to find where it is autogenerated from?

kubernetes.config.configuration is not auto generated anymore, you can edit it. Please also remove the message that it said it is auto-generated. Thanks for your contribution.

Thanks @mbohlool! kubernetes-client/python-base#18 should do the trick I think.

@mbohlool @yuvipanda how can you edit this? I have this setting because I'm threading grabbing pod information and ran into the connection pool issue above:

client_config = client.Configuration()
client_config.connection_pool_maxsize = 200
config.load_kube_config(client_configuration=client_config)
v1 = client.CoreV1Api()

if I then call pods = v1.list_namespaced_pod(namespace) I get an error where it hits localhost rather than using my kubeconfig.

I checked out the code here: https://github.com/kubernetes-client/python-base/blob/master/config/kube_config.py#L522 and thought that if I just pass in the client_configuration with the changed pool size it'd use that, but I'm overwriting something I don't mean to.

[mbohlool]

you need to pass your client_config to client.CoreV1Api() call otherwise it will use the default one which is localhost. it should be something like client.CoreV1Api(config=client_config)

Thanks for the help!
