<p>Retrieves a collection of fleet resources in an Amazon Web Services Region. You can call this operation to get fleets in a previously selected default Region (see <a href="https://docs.aws.amazon.com/credref/latest/refdocs/setting-global-region.html">https://docs.aws.amazon.com/credref/latest/refdocs/setting-global-region.html</a>or specify a Region in your request. You can filter the result set to find only those fleets that are deployed with a specific build or script. For fleets that have multiple locations, this operation retrieves fleets based on their home Region only.</p> <p>This operation can be used in the following ways: </p> <ul> <li> <p>To get a list of all fleets in a Region, don't provide a build or script identifier. </p> </li> <li> <p>To get a list of all fleets where a specific custom game build is deployed, provide the build ID.</p> </li> <li> <p>To get a list of all Realtime Servers fleets with a specific configuration script, provide the script ID. </p> </li> </ul> <p>Use the pagination parameters to retrieve results as a set of sequential pages. </p> <p>If successful, a list of fleet IDs that match the request parameters is returned. A NextToken value is also returned if there are more result pages to retrieve.</p> <note> <p>Fleet resources are not listed in a particular order.</p> </note> <p> <b>Learn more</b> </p> <p> <a href="https://docs.aws.amazon.com/gamelift/latest/developerguide/fleets-intro.html">Setting up Amazon GameLift fleets</a> </p>
