A new bootstrapping role for monitoring endpoints was introduced in kubernetes/kubernetes#93311 and this PR intends to add documentation to our bootstrapped default RBAC policies/roles/role-bindings/groups so that it reflects the new addition.

Given the comment that this should be for 1.20, I wonder if we should consider alternate ways to handling this or potentially close this PR - waiting for the 1.20 cycle to begin.

why not hold and add to the 1.20 milestone?

@logicalhan Can you update the target branch to dev-1.20 instead of master ?

Thank you @logicalhan!

Also, was just reviewing this and if you take a look at the preview https://deploy-preview-22715--kubernetes-io-master-staging.netlify.app/docs/reference/access-authn-authz/rbac/

it actually does not apply ` correctly, and looks like this. It looks like this can be solved using < tt >< /tt > (without spaces, added spaces so that it shows up in the comment) instead.

Hey @zparnold Can I get your review on this?

I believe technical review from @liggitt stands, just need a review from sig docs and we can get this approved!

Should group appear in bold?

<b>group</b>

I think the <tt> element is deprecated?
For code or endpoints, you can use backticks:
/healthz

The table data content could be formatted as:

Allows read access to control-plane monitoring endpoints such as the {{< glossary_tooltip term_id="kube-apiserver" text="kube-apiserver" >}} liveness and readiness endpoints (/healthz, /livez, /readyz), the individual health-check endpoints (/healthz/*, /livez/*, /readyz/*), and /metrics. Note that individual health check endpoints and the metric endpoint may expose sensitive information.

Hi @kbhawkey, using backticks resulted in the following (#22715 (comment)) so I suggested to change to < tt >. It doesn't seem to be deprecated as the page renders as expected (https://5f7f97dbc52f3c00071d9bee--kubernetes-io-vnext-staging.netlify.app/docs/reference/access-authn-authz/rbac/). PTAL when you can, thank you!
