When using the environment variables in the user-container, I found that there are many environment variables in the container that do not know where they came from. These variables start with the name of the current Revision, and each container contains all Revision-related environment variables under the same Knative Service.

Here is some environmental information:

These useless and unknown environment variables all begin with the name of Revison and contain all Revison.

I want to know where they came from, does it have any effect? If it doesn't work, why do you need to increase so many environment variables?

How did you determine that they are useless?
Those are injected by kubernetes.

I'm just guessing that they are useless, I mainly want to know what they are used for, and if deleting these environment variables in the user-container will have an effect.

You'll want #8439 and then set EnableServiceLinks to false I believe.

EnableServiceLinks

This is exactly what I want. Thank you.

Because we will expose the user-container to the user, we do not want to show the user too much information.
