Same as Debugging Profiles above, custom profile can be applied not only to an ephemeral containers, but also to a copied Pods or a debugging pods to debug nodes.
Although the following case uses an ephemeral container as an example, I think the title should remain more general, as it is now.
(While other examples can be provided, it would be redundant)

Furthermore, I think custom profile is an extension of debugging profile.
So it would be better for the Custom Profile section under Debugging Profiles to be at level ### instead of ##, or to add a new comprehensive section that consolidates the Debug Profile and Custom Profile.

It does not support the modification of the Pod spec.

This paragraph doesn't make sense.
If modifications to a Pod spec is not supported, why are we talking about the specific fields then?

@mochizuki875 Please check other task pages for reference on how we structure a task pages, for example, content/en/docs/tasks/configure-pod-container/assign-cpu-resource.md.

here are some more specific guidance on this.

Thank you for your advice and providing the reference.
I understand that I'm writing part of the steps section(although it's not originally explicitly stated as a comment in the markdown), but after referring to this, I was unable to understand the decisive difference from a structural perspective, sorry...

The only point that comes to mind is the following, but could you let me know specifically what the issue is?

  • Should the section title be in the imperative rather than a noun?(e.g. Apply custom profile)
  • Should headings be ## rather than ###?
  • {{< feature-state for_k8s_version="v1.31" state="beta" >}} should not be included?

The only point that comes to mind is the following, but could you let me know specifically what the issue is?

My suggestion was to improve the structure of the page so that it is more like a "task" page.

* Should the section title be in the imperative rather than a noun?(e.g. Apply custom profile)

Yes.

* Should headings be `##` rather than `###`?

## stands for <H2> in HTML, ### stands for <H3> in HTML. The top-level headings for a page should be ##.

* `{{< feature-state for_k8s_version="v1.31" state="beta" >}}` should not be included?

The feature-state stanza is a Docsy shortcode. It is included to indicate that the content
is about a feature under development. Use it when necessary.

Are you suggesting that, rather than limiting the scope of this PR to the custom profile, we should revamp the entire page to follow the task style in this PR?

If so, how about addressing it as a separate issue?
The purpose of this PR is to inform users about the Custom Profile, which has not yet been documented, and I believe this provides some value to the users.
e.g.) related kubernetes/kubectl#1650

I'm okay with that, considering that this PR is not about a new task page.
But please do as much as you can to follow the desired structure of a task page.

OK, so I've restructured the section regarding profiles with some fixes.
