# Choose a pool to deploy your app¶

tsuru has a concept of pool, a group of machines that will run the application code. Pools are defined by the cloud admin as needed and users can choose one of them in the moment of app creation.

Users can see which pools are available using the command tsuru pool-list:

$tsuru pool-list +---------+--------------+ | Team | Pools | +---------+--------------+ | team1 | pool1, pool2 | +---------+--------------+  So, in app-create, users can choose the pool using the -o/–pool pool_name flag: $ tsuru app-create app_name platform -o pool1


There’s no need to specify the pool when the user has access to only one pool.
