- Descriptive information: Describe the function of the node.
- Task priority: When the number of worker threads is insufficient, execute in
the order of priority from high to low, and tasks with the same priority will
execute in a first-in first-out order.
- Worker grouping: Assign tasks to the machines of the worker group to
execute. If `Default` is selected, randomly select a worker machine for
execution.
+- Environment name: The environment in Security, if not configured, it will
not be used.
+- Task group name: The group in Resources, if not configured, it will not be
used.
- Times of failed retry attempts: The number of times the task failed to
resubmit. You can select from drop-down or fill-in a number.
- Failed retry interval: The time interval for resubmitting the task after a
failed task. You can select from drop-down or fill-in a number.
+- Delay execution time: Task delay execution time.
- Timeout alarm: Check the timeout alarm and timeout failure. When the task
runs exceed the "timeout", an alarm email will send and the task execution will
fail.
- Condition: You can configure multiple conditions for the switch task. When
the conditions are satisfied, execute the configured branch. You can configure
multiple different conditions to satisfy different businesses.
- Branch flow: The default branch flow, when all the conditions are not
satisfied, execute this branch flow.
-## Detail
+## Task Example
-Here we have three tasks, the dependencies are `A -> B -> [C, D]`, and
`task_a` is a shell task and `task_b` is a switch task
+This is demonstrated using one switch task and three shell tasks.
-- In task A, a global variable named `id` is defined through [global
variable](../parameter/global.md), and the declaration method is
`${setValue(id=1)}`
-- Task B adds conditions and uses global variables declared upstream to
achieve conditional judgment (Note: switch can get the global variables value,
as long as its direct or indirect upstream have already assigned the global
variables before switch acquires). We want to execute task C when `id = 1`,
otherwise run task D
- - Configure task C to run when the global variable `id=1`. Then edit `${id}
== 1` in the condition of task B, and select `C` as branch flow
- - For other tasks, select `D` as branch flow
+
-The following shows the switch task configuration:
+### Create a workflow
-
+Create a new switch task, and three shell tasks downstream. The shell task is
not required.
+The switch task needs to be connected with the downstream task to configure
the relationship before the downstream task can be selected.
