Add fsGroup value to admission-webhooks/job-patch charts #8267

Simple feature request update that adds a configurable fsGroup field to the patch job in values.yaml and updates the related templates files to contain a reference to this new fsGroup value.

What this PR does / why we need it:

We had an issue when migrating from an older version of the deprecated nginxinc ingress controller to the one provided by Kubernetes which was preventing the update of our Kubernetes cluster

The primary problem was when we were deploying our application to AWS EKS, we discovered that our secret tokens lacked permissions to be able to be referenced by the admission-webhooks/job-patch/{job-createSecret | job-patchWebhook} charts.

We found that the issue was by default there is no assigned gid, or if it was assigned it had a value of 0. This issue is discussed here and here as well as a few other threads.

Types of changes

  • Bug fix (non-breaking change which fixes an issue)
  • New feature (non-breaking change which adds functionality)
  • Breaking change (fix or feature that would cause existing functionality to change)
  • Documentation only

Which issue/s this PR fixes

I looked through the open issues and couldn't find anyone else referencing this particular problem other than those error threads previous linked.

How Has This Been Tested?

I've tested the changes in EKS and was able to deploy and configure a Stackstorm instance routed through ingress-nginx. Prior to the changes the ingress controller would not be able to run any pods and would fail with:

W0110 19:40:34.679601       8 client_config.go:620] error creating inClusterConfig, falling back to default config: open /var/run/secrets/kubernetes.io/serviceaccount/token: permission denied
F0110 19:40:34.680080       8 main.go:281] Error while initiating a connection to the Kubernetes API server. This could mean the cluster is misconfigured (e.g. it has invalid API server certificates or Service Accounts configuration). Reason: open /var/run/secrets/kubernetes.io/serviceaccount/token: permission denied

I followed the dev-env setup guide and ran the associated dev-environment tests against my repo and was not alerted to any major errors. I will mention that I had run into one error during dev-env testing which was confirmed to be a bug in this slack thread, and this bug exists even without modifying the base repo.

Checklist:

  • My change requires a change to the documentation.
  • I have updated the documentation accordingly.
  • I've read the CONTRIBUTION guide
  • I have added tests to cover my changes.
  • All new and existing tests passed.

There's one or two things I'm not sure of:

  • Whether the default fsGroup should be set to 2000 matching the uid, or set to 0 which would emulate existing deployment functionality. I could see how setting 2000 could affect pre-existing deployments' behaviour.
  • If this will require specific documentation & testing updating

My use has been pretty minimal; at this time I'm not aware of any other major breaking changes caused by this update.

Hi @dylan-bitovi. Thanks for your PR.

I'm waiting for a kubernetes member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

Updated confusing error (kubernetes#8262)

Add a certificate info metric (kubernetes#8253)

When the ingress controller loads certificates  (new ones or following a
secret update), it performs a series of check to ensure its validity.

In our systems, we detected a case where, when the secret object is
compromised, for example when the certificate does not match the secret
key, different pods of the ingress controller are serving a different
version of the certificate.

This behaviour is due to the cache mechanism of the ingress controller,
keeping the last known certificate in case of corruption. When this
happens, old ingress-controller pods will keep serving the old one,
while new pods, by failing to load the corrupted certificates, would
use the default certificate, causing invalid certificates for its
clients.

This generates a random error on the client side, depending on the
actual pod instance it reaches.

In order to allow detecting occurences of those situations, add a metric
to expose, for all ingress controlller pods, detailed informations of
the currently loaded certificate.

This will, for example, allow setting an alert when there is a
certificate discrepency across all ingress controller pods using a query
similar to `sum(nginx_ingress_controller_ssl_certificate_info{host="name.tld"})by(serial_number)`

This also allows to catch other exceptions loading certificates (failing
to load the certificate from the k8s API, ...
