<p>The capacity provider strategy to use for the task set.</p> <p>A capacity provider strategy consists of one or more capacity providers along with the <code>base</code> and <code>weight</code> to assign to them. A capacity provider must be associated with the cluster to be used in a capacity provider strategy. The <a>PutClusterCapacityProviders</a> API is used to associate a capacity provider with a cluster. Only capacity providers with an <code>ACTIVE</code> or <code>UPDATING</code> status can be used.</p> <p>If a <code>capacityProviderStrategy</code> is specified, the <code>launchType</code> parameter must be omitted. If no <code>capacityProviderStrategy</code> or <code>launchType</code> is specified, the <code>defaultCapacityProviderStrategy</code> for the cluster is used.</p> <p>If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New capacity providers can be created with the <a>CreateCapacityProvider</a> API operation.</p> <p>To use a Fargate capacity provider, specify either the <code>FARGATE</code> or <code>FARGATE_SPOT</code> capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used.</p> <p>The <a>PutClusterCapacityProviders</a> API operation is used to update the list of available capacity providers for a cluster after the cluster is created.</p>

<p>The metadata that you apply to the task set to help you categorize and organize them. Each tag consists of a key and an optional value. You define both. When a service is deleted, the tags are deleted.</p> <p>The following basic restrictions apply to tags:</p> <ul> <li> <p>Maximum number of tags per resource - 50</p> </li> <li> <p>For each resource, each tag key must be unique, and each tag key can have only one value.</p> </li> <li> <p>Maximum key length - 128 Unicode characters in UTF-8</p> </li> <li> <p>Maximum value length - 256 Unicode characters in UTF-8</p> </li> <li> <p>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: + - = . _ : / @.</p> </li> <li> <p>Tag keys and values are case-sensitive.</p> </li> <li> <p>Do not use <code>aws:</code>, <code>AWS:</code>, 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.</p> </li> </ul>
