Hello everyone,

In the interest of proceeding with the deprecation of Jessie in our infrastructure, SRE ServiceOps will stop maintaining and eventually remove the base Debian Jessie OCI container image[1], also known as wikimedia-jessie, from our docker registry.

If you rely on this image in any way, you are strongly urged to move to our Debian Stretch or Buster images, which will continue to be maintained for some time (for more information see https://wikitech.wikimedia.org/wiki/Operating_system_upgrade_policy).

A tentative timeline follows:

* 2020-07-02. https://gerrit.wikimedia.org/r/c/operations/puppet/+/587529 will be merged. This will mean the image will no longer be receiving any kind of updates but will still be possible to be pulled from the registry. Workflows are not expected to break. * 2020-08-03. Removal of all the image tags and versions of the above image will happen. That will mean that the image will no longer be able to be pulled from the registry. If you have any workflows that rely on pulling this image from the registry, they are expected to break on this date. Images that have already been published and are based on the Jessie image however will not be touched and will still be pullable.

If you have a workflow that will break after the 2020-08-03 mark and are unable to alter it, please reach out to us.

Following the above, we will also investigate whether removing image versions and tags that depend on the removed image makes sense.

Note that this is the first time we remove a base image from our registry and as such we are building knowledge and experience around this.
