                  The value of the key-value pair. For environment variables, this is the value of the environment variable.

        • healthStatus (string) --

          The health status for the task, which is determined by the health of the essential containers in the task. If all essential containers in the task are reporting as HEALTHY , then the task status also reports as HEALTHY . If any essential containers in the task are reporting as UNHEALTHY or UNKNOWN , then the task status also reports as UNHEALTHY or UNKNOWN , accordingly.

          Note

          The Amazon ECS container agent does not monitor or report on Docker health checks that are embedded in a container image (such as those specified in a parent image or from the image's Dockerfile) and not specified in the container definition. Health check parameters that are specified in a container definition override any Docker health checks that exist in the container image.

        • tags (list) --

          The metadata that you apply to the task to help you categorize and organize them. Each tag consists of a key and an optional value, both of which you define.

          The following basic restrictions apply to tags:

          • Maximum number of tags per resource - 50

          • 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: + - = . _ : / @.

          • Tag keys and values are case-sensitive.

          • Do not use aws: , AWS: , or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for AWS use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

RunTask (updated) Link ¶
Changes (response)
{'tasks': {'containers': {'runtimeId': 'string'}}}

Starts a new task using the specified task definition.

You can allow Amazon ECS to place tasks for you, or you can customize how Amazon ECS places tasks using placement constraints and placement strategies. For more information, see Scheduling Tasks in the Amazon Elastic Container Service Developer Guide .

Alternatively, you can use StartTask to use your own scheduler or place tasks manually on specific container instances.

The Amazon ECS API follows an eventual consistency model, due to the distributed nature of the system supporting the API. This means that the result of an API command you run that affects your Amazon ECS resources might not be immediately visible to all subsequent commands you run. Keep this in mind when you carry out an API command that immediately follows a previous API command.

To manage eventual consistency, you can do the following:

  • Confirm the state of the resource before you run a command to modify it. Run the DescribeTasks command using an exponential backoff algorithm to ensure that you allow enough time for the previous command to propagate through the system. To do this, run the DescribeTasks command repeatedly, starting with a couple of seconds of wait time and increasing gradually up to five minutes of wait time.

  • Add wait time between subsequent commands, even if the DescribeTasks command returns an accurate response. Apply an exponential backoff algorithm starting with a couple of seconds of wait time, and increase gradually up to about five minutes of wait time.

The spread placement strategy spreads placement across available candidates evenly based on the field parameter. The binpack strategy places tasks on available candidates that have the least available amount of the resource that is specified with the field parameter. For example, if you binpack on memory, a task is placed on the instance with the least amount of remaining memory (but still enough to run the task).

    • field (string) --

      The field to apply the placement strategy against. For the spread placement strategy, valid values are instanceId (or host , which has the same effect), or any platform or custom attribute that is applied to a container instance, such as attribute:ecs.availability-zone .

          • Maximum number of tags per resource - 50

          • 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: + - = . _ : / @.

StopTask (updated) Link ¶
Changes (response)
{'task': {'containers': {'runtimeId': 'string'}}}

Stops a running task. Any tags associated with the task will be deleted.

When StopTask is called on a task, the equivalent of docker stop is issued to the containers running in the task. This results in a SIGTERM value and a default 30-second timeout, after which the SIGKILL value is sent and the containers are forcibly stopped. If the container handles the SIGTERM value gracefully and exits within 30 seconds from receiving it, no SIGKILL value is sent.

Note

The default 30-second timeout can be configured on the Amazon ECS container agent with the ECS_CONTAINER_STOP_TIMEOUT variable. For more information, see Amazon ECS Container Agent Configuration in the Amazon Elastic Container Service Developer Guide .

        • Maximum number of tags per resource - 50

        • 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: + - = . _ : / @.

        • Tag keys and values are case-sensitive.

        • Do not use aws: , AWS: , or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for AWS use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.
