Documentation

data Tag Source #

The metadata that you apply to a resource to help you categorize and organize them. Each tag consists of a key and an optional value, both of which you define.

The following basic restrictions apply to tags:

Maximum number of tags per resource - 50
For each resource, each tag key must be unique, and each tag key can have only one value.
Maximum key length - 128 Unicode characters in UTF-8
Maximum value length - 256 Unicode characters in UTF-8
If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.
Tag keys and values are case-sensitive.
Do not use aws:, AWS:, or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

See: newTag smart constructor.

Constructors

Tag'
Fields value :: Maybe Text The optional part of a key-value pair that make up a tag. A `value` acts as a descriptor within a tag category (key). key :: Maybe Text One part of a key-value pair that make up a tag. A `key` is a general label that acts like a category for more specific tag values.

newTag :: Tag Source #

Create a value of Tag with all optional fields omitted.

Use generic-lens or optics to modify other optional fields.

The following record fields are available, with the corresponding lenses provided for backwards compatibility:

$sel:value:Tag', tag_value - The optional part of a key-value pair that make up a tag. A value acts as a descriptor within a tag category (key).

$sel:key:Tag', tag_key - One part of a key-value pair that make up a tag. A key is a general label that acts like a category for more specific tag values.

tag_value :: Lens' Tag (Maybe Text) Source #

The optional part of a key-value pair that make up a tag. A value acts as a descriptor within a tag category (key).

tag_key :: Lens' Tag (Maybe Text) Source #

One part of a key-value pair that make up a tag. A key is a general label that acts like a category for more specific tag values.
