You specify stack tags with the tags property. CloudFormation automatically adds the tags to each resource in the stack that supports tagging.


Setting tags:
foo: bar
code: 123
backups: true

Where to define

The tags property can be defined in stack and stack group configuration files. If specified in a stack group, the stack group's children and stacks inherit the value. Stack groups and stacks can add new tags and overwrite individual tags they inherited from their parent by specifying a new value with the same key.


The tags property must satisfy these requirements:
  • Each tag key must be a string
  • Each tag value must be a string, a number or a boolean
