externalId
parameter contains theECS_TASK_SET_EXTERNAL_ID

. -
The
pendingCount
is0
. -
There are no tasks that are running on container instances in the
DRAINING
status. -
All tasks are reporting a healthy status from the load balancers, service discovery, and container health checks.
If any of those conditions aren't met, the stability status returns
STABILIZING
.Type: String
Valid Values:
STEADY_STATE | STABILIZING
Required: No
-
- stabilityStatusAt
-
The Unix timestamp for the time when the task set stability status was retrieved.
Type: Timestamp
Required: No
- startedBy
-
The tag specified when a task set is started. If an Amazon CodeDeploy deployment created the task set, the
startedBy
parameter isCODE_DEPLOY

- status
-
The status of the task set. The following describes each state.
- PRIMARY

-
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.

-
For each resource, each tag key must be unique, and each tag key can have only one value.
-
Maximum key length - 128 Unicode characters in UTF-8
-
Maximum value length - 256 Unicode characters in UTF-8
-
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: + - = . _ : / @.
