Enhancement Description

Deprecation plan:

  • release 1.18
    1. Mark the --redirect-container-streaming flag as deprecated. Log a warning on use.
    2. Mark the StreamingProxyRedirects feature as deprecated. Log a warning on use.
  • release 1.19 - no changes
  • release 1.20
    1. --redirect-container-streaming can no longer be enabled. If the flag is set, log an error
      and continue as though it is unset.
  • release 1.22 (previously: 1.21) Default StreamingProxyRedirects to disabled kubernetes#101647
    1. Default StreamingProxyRedirects to disabled. If there is a >= 2 version skew between master
      and nodes, and the old nodes were enabling --redirect-container-streaming, this will break
      them
      . In this case, the StreamingProxyRedirects can still be manually enabled.
  • release 1.24 (previously: 1.22)
    1. Remove the --redirect-container-streaming flag.
    2. Remove the StreamingProxyRedirects feature.

Hi @tallclair, -- 1.19 Enhancements Lead here. I see from the KEP that no work is planned for 1.19. I just wanted to confirm if that is still the case?

Thank you!

Issues go stale after 90d of inactivity.
Mark the issue as fresh with /remove-lifecycle stale.
Stale issues rot after an additional 30d of inactivity and eventually close.

If this issue is safe to close now please do so with /close.

Send feedback to sig-testing, kubernetes/test-infra and/or fejta.

Hi @tallclair

Enhancements Lead here, can you confirm whether this will have work in 1.20? (alpha/beta/GA?)

Thanks!
Kirsten

Yes, this has some work targeting v1.20. I hoisted the rollout plan to the issue description.

So I noticed that this is a Deprecation rollout, so I'm wondering how to track this against alpha/beta/stable.. Maybe this could be beta? But I feel like I'm forcing it 🤔

WDYT @tallclair @palnabarun ?

Yeah, I don't think alpha/beta/ga makes sense here. I don't know enough about the feature tracking process to know what the alternatives are.

@tallclair let me check on this and i'll report back!

After discussing, we agree it's important to track & publicize, so we made a new status so that we can track this as a drumroll deprecation! 😄

Hey @tallclair !

Since your Enhancement is scheduled to be in 1.20, please keep in mind the important upcoming dates:
Friday, Nov 6th: Week 8 - Docs Placeholder PR deadline <--- Pretty sure you'll want to do this one for the deprecation
Thursday, Nov 12th: Week 9 - Code Freeze

As a reminder, please link all of your k/k PR as well as docs PRs to this issue so we can track them.

Thanks!
Kirsten 😃

Hello @tallclair , 1.20 Docs shadow here.

Does this enhancement work planned for 1.20 require any new docs or modification to existing docs?

If so, please follows the steps here to open a PR against the dev-1.20 branch in the k/website repo. This PR can be just a placeholder at this time and must be created before Nov 6th.

Also take a look at Documenting for a release to get yourself familiarize with the docs requirement for the release.

Thank you!

Hi @tallclair

Looks like kubernetes/kubernetes#95935 is merged and that was the only PR for 1.20 - correct?

As a note: Code Freeze is coming up in 2 days on Thursday, November 12th. All PRs must be merged by that date, otherwise an Exception is required.

Thanks!

Hey @tallclair, 1.22 Enhancements Lead here.

While a depreciation doesn't really go through the same criteria as a graduation, there's still a few things I'd like to clarify about your KEP:

  • Can you set the latest-milestone key in your kep.yaml to be "v1.22".
  • Also in the kep.yaml file, should the state still be implementable?
  • Can you update the rollout plan in your KEP to match this issue? (i.e., specify which is coming in 1.22 and which in 1.24)

Also I see that SIG API Machinery is listed as a participating SIG in your KEP. Will they need to do anything towards this deprecation in 1.22, and if so are they aware of that?

We need to update https://kubernetes.io/docs/reference/command-line-tools-reference/feature-gates/#feature-gates-for-graduated-or-deprecated-features with the state of StreamingProxyRedirects and ValidateProxyRedirects.

@tallclair @pacoxu - would you be able to do a PR on the KEP.yaml to change the state to implemented? At that point we should be able to close the issue.

Thanks!
