descheduler VS python

maybe descheduler can help? https://github.com/kubernetes-sigs/descheduler

Surprised this wasn't suggested yet, you can also use a software like the k8s Descheduler that executes periodically to rebalance your workloads across the existing nodes.

Here an example of coordination api in Go https://github.com/kubernetes-sigs/descheduler/commit/3cbae5e72ba53447a609e6001755ff395e6eeceb https://github.com/kubernetes-sigs/descheduler/commit/0a52af9ab82a52fd8c864a81f4033736f11aab34

This is something a (now former) colleague of mine pointed out: that the kubernetes descheduler can enforce a maximum lifetime[0] that sort of forces continual reboots. So if your system cannot tolerate running for a long time continously, this is one method to gracefully restart long running pods.

no it does not... thats why tools like https://github.com/kubernetes-sigs/descheduler exist..

You might want to take a look at descheduler: https://github.com/kubernetes-sigs/descheduler

One option is to use list_namespace(), as described in https://github.com/kubernetes-client/python/blob/master/kubernetes/docs/CoreV1Api.md

I have checked the python version == 2.7 and pip freeze - ipaddress==1.0.22, urllib3==1.24.1 and websocket-client==0.54.0 are the versions which satisfy the requirement - as mentioned here: https://github.com/kubernetes-client/python/blob/master/README.md#hostname-doesnt-matchfollowed the issue on this thread - https://github.com/kubernetes-client/python/issues/36 - not much help.

kubectl apply -f class.yamlkubectl apply -f rbac.yamlkubectl apply -f deployment-arm.yaml I want to use the kubernetes-client written in python to replace it. My current code, loads the there yaml files (using pyyaml), edits them a bit, inserts into a file and use the command line kubectl to execute those three commands. Some of the code:

In the Kubernetes Python client code it's called "klass":

https://github.com/kubernetes-client/python/blob/1a0cb469528e6b2bdeb3eb2c06945f1c22303dfd/kubernetes/client/api_client.py#L266

and in Apache ecosystem it's called clazz:

Just thought it was amusing and wanted to share

One way is to use configmap lock https://github.com/kubernetes-client/python/tree/master/kubernetes/base/leaderelection

I'm having trouble connecting to the kubernetes python client even though I'm following the examples here in the api.

As you can imagine, that's a lot of functions to choose from, luckily all of them are listed in docs and you can click on any one of them to get an example of its usage.
