-- | Information about a set of Amazon ECS tasks in an CodeDeploy deployment.
-- An Amazon ECS task set includes details such as the desired number of
-- tasks, how many tasks are running, and whether the task set serves
-- production traffic. An CodeDeploy application that uses the Amazon ECS
-- compute platform deploys a containerized application in an Amazon ECS
-- service as a task set.

-- /See:/ 'newECSTaskSet' smart constructor.
data ECSTaskSet = ECSTaskSet'
  { -- | The number of tasks in a task set. During a deployment that uses the
    -- Amazon ECS compute type, CodeDeploy instructs Amazon ECS to create a new
    -- task set and uses this value to determine how many tasks to create.
    -- After the updated task set is created, CodeDeploy shifts traffic to the
    -- new task set.
    desiredCount :: Prelude.Maybe Prelude.Integer,
    -- | A unique ID of an @ECSTaskSet@.
    identifer :: Prelude.Maybe Prelude.Text,
    -- | The number of tasks in the task set that are in the @PENDING@ status
    -- during an Amazon ECS deployment. A task in the @PENDING@ state is
    -- preparing to enter the @RUNNING@ state. A task set enters the @PENDING@
    -- status when it launches for the first time, or when it is restarted
    -- after being in the @STOPPED@ state.
    pendingCount :: Prelude.Maybe Prelude.Integer,
    -- | The number of tasks in the task set that are in the @RUNNING@ status
    -- during an Amazon ECS deployment. A task in the @RUNNING@ state is
    -- running and ready for use.

    -- | The status of the task set. There are three valid task set statuses:
    --
    -- -   @PRIMARY@: Indicates the task set is serving production traffic.

    --

    --     and their corresponding targets are being deregistered from their
    --     target group.

    -- | The target group associated with the task set. The target group is used
    -- by CodeDeploy to manage traffic to a task set.

-- The following record fields are available, with the corresponding lenses provided

--
-- 'desiredCount', 'eCSTaskSet_desiredCount' - The number of tasks in a task set. During a deployment that uses the
-- Amazon ECS compute type, CodeDeploy instructs Amazon ECS to create a new
-- task set and uses this value to determine how many tasks to create.
-- After the updated task set is created, CodeDeploy shifts traffic to the

--
-- 'identifer', 'eCSTaskSet_identifer' - A unique ID of an @ECSTaskSet@.
--
-- 'pendingCount', 'eCSTaskSet_pendingCount' - The number of tasks in the task set that are in the @PENDING@ status
-- during an Amazon ECS deployment. A task in the @PENDING@ state is
-- preparing to enter the @RUNNING@ state. A task set enters the @PENDING@
-- status when it launches for the first time, or when it is restarted
-- after being in the @STOPPED@ state.
--
-- 'runningCount', 'eCSTaskSet_runningCount' - The number of tasks in the task set that are in the @RUNNING@ status
-- during an Amazon ECS deployment. A task in the @RUNNING@ state is
-- running and ready for use.
--
-- 'status', 'eCSTaskSet_status' - The status of the task set. There are three valid task set statuses:
--
-- -   @PRIMARY@: Indicates the task set is serving production traffic.
--
-- -   @ACTIVE@: Indicates the task set is not serving production traffic.
--
-- -   @DRAINING@: Indicates the tasks in the task set are being stopped
