@cwperks Can you please update the current status?

[cwperks]

@peternied Please provide on update on running CI on windows

For the issue of not having a batch equivalent of the install_demo_configuration.sh (opensearch-project/security#2148) there is a PR, but we are facing an issue with the automated validation of the change against main.

The plugin_install workflow has been extended to verify the installation on both linux and windows, but the issue being faced now is that an opensearch node cannot be started on the windows-latest runner because windows-latest runs as admin and the node will not start if its run as root. This is actively being worked on and we hope to find a solution shortly.

The build-time validation does work on 2.x, but only because the automatic backport of this change failed: opensearch-project/OpenSearch#4656

[peternied]

This is queued up to be worked on next, as soon as I get the backend plugin ready for review for CI on Windows opensearch-project/security#2190

[peternied]

Note, I'm moving the integration test work out into its own task. It was not a core requirement for the windows platform release and we can fast follow to get it included.

I am not sure why we say integration tests weren't part of this work. Reopening. Let's close when there's no gap between testing on Linux and Windows.

Hi, just want to make sure this issue is closed, if all the tasks are completed.

Thanks.

[peternied]

This is not complete, it is still a work in progress, I've removed the 2.4.0 label

[CEHENKLE]

@peternied What release are you targeting?

[peternied]

@CEHENKLE Missed the 2.5.0 release, targeting 2.6.0 @RyanL1997 is actively working this, see the follow PR for status:

[peternied]

@RyanL1997 as the one who took this on, would you do the honors and close this issue?

Closing this one since the #1275 has been merged. Thank you all for the support!
