What is a data image tag?

A data image tag is a way to provide additional metadata for a data image by labeling it with a custom string value. Data images can have multiple tags.

Referencing an existing data image with a tag in commands can be done in the format name:tag (see CLI Reference for examples).

A tag can not be applied to data containers.

Nomenclature rules

Data image tags must:

• Be less than or equal to 128 characters.
• Be lower case.
• Not start with a period or dash.
• Contain only the following characters:
  • a-z
  • 0-9
  • -
  • _

Example

In this example, we will add two tags to the yaml definition file defining our empty SQL Server 2019 data image:

sourceType: empty
name: dev
engine: mssql
version: 2019
tags:
 - "v1.0"
 - "development"
