Create a gallery for storing and sharing resources
An Azure Compute Gallery (formerly known as Shared Image Gallery) simplifies sharing resources, like images and application packages, across your organization.
The Azure Compute Gallery lets you share custom VM images and application packages with others in your organization, within or across regions, within a tenant. Choose what you want to share, which regions you want to make them available in, and who you want to share them with. You can create multiple galleries so that you can logically group resources.
The gallery is a top-level resource that can be shared in multiple ways:
|Sharing with:||People||Groups||Service Principal||All users in a specific subscription (or) tenant||Publicly with all users in Azure|
|RBAC + Direct shared gallery||Yes||Yes||Yes||Yes||No|
|RBAC + Community gallery||Yes||Yes||Yes||No||Yes|
Allowed characters for gallery name are uppercase (A-Z) and lowercase (a-z) letters, digits (0-9), dots (or periods)
., and underscores
_. The gallery name can't contain dashes
-. Gallery names must be unique within your subscription.

Create a community gallery
A community gallery is shared publicly with everyone. To create a community gallery, you create the gallery first, then enable it for sharing. The name of public instance of your gallery is the prefix you provide, plus a unique GUID.
During the preview, make sure that you create your gallery, image definitions, and image versions in the same region in order to share your gallery publicly.
Azure Compute Gallery – community galleries is currently in PREVIEW and subject to the Preview Terms for Azure Compute Gallery - community gallery.
To publish a community gallery, you'll need to set up preview features in your Azure subscription. Creating VMs from community gallery images is open to all Azure users.
When creating an image to share with the community, you need to provide contact information. This information is shown publicly, so be careful when providing:
- Community gallery prefix
- Publisher support email
- Publisher URL
- Legal agreement URL
Information from your image definitions is also publicly available, like what you provide for Publisher, Offer, and SKU.
Only the owner of a subscription, or a user or service principal assigned to the
Compute Gallery Sharing Admin role at the subscription or gallery level, can enable a gallery to go public to the community. To assign a role to a user, group, service principal or managed identity, see Steps to assign an Azure role.
--public-name-prefix value is used to create a name for the public version of your gallery. The
--public-name-prefix is the first part of the public name, and the last part will be a GUID, created by the platform, that is unique to your gallery.
