Credentials appear in debug logs

[jtwb]

What happened (please include outputs or screenshots):

Kubernetes-client creates debug log lines for all REST API call response bodies. When using kubernetes-client to create kubernetes Secret objects, this presents an issue as the raw contents of the secret are logged.

The issue can be worked around by forcing kubernetes-client to never generate debug logs via log configuration (e.g. logging.dictConfig).

What you expected to happen:

Calling client.CoreV1Api().create_namespaced_secret() must never log the raw secret.

How to reproduce it (as minimally and precisely as possible):

    body = client.V1Secret(
        metadata=client.V1ObjectMeta(name=secret_name),
        data={"secret_value": base64.b64encode(secret_value.encode()).decode('utf-8')}
    core_client = client.CoreV1Api()
    core_client.create_namespaced_secret(settings.K8S_NAMESPACE, body)

Anything else we need to know?:

This appears to be the offending line:

python/kubernetes/client/rest.py

Lines 234 to 235 in 7a278c7

	# log response body
	logger.debug("response body: %s", r.data)

Environment:

• Kubernetes version (kubectl version): v1.30.0
• OS (e.g., MacOS 10.13.6): Linux 33b1220370b0 6.4.16-linuxkit #1 SMP PREEMPT Thu Nov 16 10:49:20 UTC 2023 aarch64 GNU/Linux
• Python version (python --version): Python 3.11.3
• Python client version (pip list | grep kubernetes): 29.0.0

Does kubectl -v=9 exclude some part of Secret content from the HTTP body logging?

I think the debug log logging all HTTP request and response body is working as intended. Marking this as a feature request.
