Annotations and labels

You can use annotations and labels with Infrastructure Manager. They're not required. This document lists the resources to which you can attach labels and annotations, and describes how you can use them and where you can view them. To use annotations or labels with Infra Manager, use the --annotation and --label flags.

What are annotations and labels?

Annotations are key-value pairs of free-form text. You can use them to attach arbitrary information associated with the resource.

You can use labels to organize resources. For example, you can apply logic based on label selection.

Annotations are used for storing non-identifying information typically used by client tools to store arbitrary data attached to a resource, while labels are typically used to organize resources.

For more information about using annotations with Google Cloud, see annotations AIP documentation. To learn more about using labels, see the labels overview documentation.

Annotation and label constraints

As with annotations, labels are key-value pairs that must conform to the following limitations:

  • Keys and values both must be 128 bytes or less.
  • Keys and values can contain only lowercase letters, numeric characters, underscores, and dashes.
  • Keys must start with a lowercase letter or international character.

  • All characters must use UTF-8 encoding. International characters are allowed. For example:

    --annotation="appVersion=v.1.2.3,environment=production"

Use annotations and labels with Infra Manager

The use of annotations and labels can be applied in a variety of ways across your Google Cloud infrastructure.

When you create or update deployments with Infra Manager, you can use annotations and labels to monitor deployments or query sets of information. For more information, see deploy infrastructure using Infra Manager, update a deployment, or preview a deployment.
