I think the comms around this are a bit confusing as it seems from their FAQ that the retention period only applies for images that have been neither pushed nor pulled within that retention window:

From the FAQ:

What is a container image retention limit and how does it affect my account?
Image retention is based on the activity of each individual image stored within a user account. If an image has not either been pulled or pushed in the amount of time specified in your subscription plan, the image will be tagged “inactive.” Any images that are tagged as “inactive” will be scheduled for deletion.

@dims: Closing this issue.

This only applies to "inactive" images if you read the FAQ, odd that it wasn't in the email.

Edit: ninja-ed!

@thecrudge which repo?

You mentioned a PR number.. where is that PR? Could you link to it directly? github.com/kubernetes/redis doesn't exist.

kubernetes/website#14106

from k8s.io.

@thecrudge replied requesting changes on that PR. thanks for the catch!

from k8s.io.

To document things further, looks like this image was still referenced as recently as October 2018: kubernetes/kubernetes#69631

from k8s.io.

@spiffxp we have changed our configuration to now use k8s.gcr.io/pause image. From kata side, the kubernetes/pause image can now be deleted.
Thanks

I suggest we plan to remove kubernetes/pause after v1.16 goes out the door, per our 3 version support policy (ref: https://kubernetes.io/docs/setup/release/version-skew-policy/), and given that the above PR implies we stopped using this image in v1.13

from k8s.io.

@spiffxp +1 to remove kubernetes/pause after v1.16 goes out the door

What's the status of this?

from k8s.io.

Looks like they have fixed it kata-containers/tests#1526 so we should be able to clean things up now.

from k8s.io.

We have 1.17 out so we should be able to finish this in 2020 I guess.

from k8s.io.

@spiffxp do you think we can delete the pause image now?

from k8s.io.

/remove-priority important-soon
/priority backlog
It's really low on my priority list at this point; it would feel great to finally get this done, but I'm juggling too much right now

from k8s.io.

Docker is changing their ToS especially important is this part about retention:

Docker is introducing a container image retention policy which will be enforced starting November 1, 2020.
The container image retention policy will apply to the following plans:
  Free plans will have a 6 month image retention limit
  Pro and Team plans will have unlimited image retention

Assuming we are on a free plan the last images will go away on November 1. Might be a good time to tackle the full retirement of the org once all images are removed by us or docker.

from k8s.io.

I am very tempted to delete the pause image now and be done with it, since we're well past v1.16.

OTOH, we could give one last final warning and say once v1.19 is released, we're removing kubernetes/pause.

What do folks think?

from k8s.io.

Thanks for the clarification. Would have expected that detail to be worth putting next to the retention notice ^^
Anyway happy to have this cleaned up nonetheless.

from k8s.io.

+1 let's please clean it up!

from k8s.io.

Also I think:
/sig security

from k8s.io.

Cleaning up these unmaintained images has helped avoid security concerns.
