Overview of the Issue

I have a Windows custom managed image that I’m using to build a new golden image and publish it to a Shared Image Gallery. All the necessary Azure resources are already deployed, configured, and functioning correctly.

However, when I run packer validate, I receive an error indicating that I must provide values for the managed image name and resource group.

This suggests that Packer expects to create two artifacts:

A managed image, and

A Shared Image Gallery (SIG) image version.

Based on the documentation, though, it should be possible to publish directly to the Shared Image Gallery without creating a managed image.

Reproduction Steps

• Builds a custom image for Azure (starting from a Marketplace or base image).
• Sets only the custom_managed_image_name and custom_managed_image_resource_group_name (not the older managed_image_* fields).
• Publishes the result to a Shared Image Gallery (SIG).
• Passes packer validate and packer build cleanly
