Recent changes to v1_node_condition.py causing ValueError for MCEHardwareErrors on Oracle OKE cloud platform

[koaps]

Changes for 23.3.0: b227345

Includes a hard coded set of conditions which may not include all supported conditions for different cloud providers:

https://github.com/kubernetes-client/python/blob/master/kubernetes/client/models/v1_node_condition.py#L217

On Oracle's OKE cloud platform, it includes an additional condition: MCEHardwareErrors

Which is causing a ValueError when the 23.3.0 client is used to list nodes:

  File "/usr/local/lib/python3.6/site-packages/kubernetes/client/models/v1_node_condition.py", line 221, in type
    .format(type, allowed_values)
ValueError: Invalid value for `type` (MCEHardwareErrors), must be one of ['DiskPressure', 'MemoryPressure', 'NetworkUnavailable', 'PIDPressure',

Node conditions should be more dynamic based on the cloud provider used.

Same for GCP/GKE:

.../lib/python3.9/site-packages/kubernetes/client/models/v1_pod_readiness_gate.py", line 78, in condition_type
    raise ValueError(
ValueError: Invalid value for `condition_type` (cloud.google.com/load-balancer-neg-ready), must be one of ['ContainersReady', 'Initialized', 'PodScheduled', 'Ready']

This is about pod conditions or pod readiness gates, but it looks to me like is has the same root cause as the node condition issue of @koaps

Edit: it happened first after upgrading from 21.7.0 to 23.3.0

I have the same issue :

File "/usr/lib/python3.6/site-packages/kubernetes/client/models/v1_node_condition.py", line 221, in type

[2022-03-02T09:48:00.771Z] E                 .format(type, allowed_values)

[2022-03-02T09:48:00.771Z] E             ValueError: Invalid value for `type` (FrequentDockerRestart), must be one of ['DiskPressure', 'MemoryPressure', 'NetworkUnavailable', 'PIDPressure', 'Ready']

Piling on here .. Getting similar error in AWS world in combination with AWS load balancer controller which injects readiness gate to pods .
Below is the error I see :

File "../lib/python3.9/site-packages/kubernetes/client/models/v1_pod_readiness_gate.py", line 52, in __init__
   self.condition_type = condition_type
 File "../lib/python3.9/site-packages/kubernetes/client/models/v1_pod_readiness_gate.py", line 78, in condition_type
   raise ValueError(
ValueError: Invalid value for `condition_type` (target-health.elbv2.k8s.aws/k8s-<name>-b77a905f9d), must be one of ['ContainersReady', 'Initialized', 'PodScheduled', 'Ready']

Same for Azure/AKS

ValueError: Invalid value for type (ContainerRuntimeProblem), must be one of ['DiskPressure', 'MemoryPressure', 'NetworkUnavailable', 'PIDPressure', 'Ready']

This is being fixed in upstream. We will cut a new 1.23 client to backport the fix once the PR kubernetes/kubernetes#108740 is merged

[iamkarlson]

Is there any mitigation available while a permanent fix is being developed yet?

Is there any mitigation available while a permanent fix is being developed yet?

We faced the issue too. We would like to know a workaround until a new version will be released.
