Description

Azure Machine Images can't be renamed, the only option available to mutate an image metadata as it progresses through a validation pipeline are the tags, we use this for marking the state of an image (i.e. RELEASE_STATUS=RC or RELEASE_STATUS=GA). The current regex-on-name filter means that once an image is published, it's available for use, which isn't desirable as it may not have passed testing yet.

New or Affected Resource(s)

• Data Source: azurerm_image

Potential Terraform Configuration

data "azurerm_image" "search" {
  name                = "search-api"
  resource_group_name = "packerimages"
  tags = {
    RELEASE_STATUS = "GA"
  }
}

• this would be very similar to the AWS AMI data source: https://registry.terraform.io/providers/hashicorp/aws/latest/docs/data-sources/ami

Hi @simonmcc thanks for this issue!

I believe this is a very good idea and we already have some similar functionality for shared image version, see this data source. We could deliver something similar to azurerm_image by introducing a new data source azurerm_images

I would like also to see the possibility of filtering tags with regular expression
