New Data Source: aws_ecs_task_execution

[jar-b]

Description

The aws_ecs_task_execution data source will enable use cases when a one-time task needs to run on an existing ECS cluster.

As this data source wraps the RunTask API, it will provision tasks on every read operation where the input attributes are known. This may include terraform plan commands, and should be used with caution for any tasks that cannot safely run multiple instances in parallel.

Relations

Adapted from #12096
Closes #1703

References

This data source was modeled after aws_lambda_function_invocation.

Thanks for the addition! A question around the execution during a plan, or any read operation. How difficult would it be to implement something similar to the null_resources triggers which would allow for this to be a resource that is only executed once until a trigger is changed? Executing on read I suspect is going to raise a lot of issues - just wondering if the functionality used in the null resource could be adapted for these one off type resources until a user wants to re-run again

Or, instead of adding a triggers argument, perhaps rely on the standard replace_triggered_by argument.
