DeleteTaskDefinitions
Deletes one or more task definitions.
You must deregister a task definition revision before you delete it. For more information, see DeregisterTaskDefinition.
When you delete a task definition revision, it is immediately transitions from the
INACTIVE to DELETE_IN_PROGRESS. Existing tasks and
services that reference a DELETE_IN_PROGRESS task definition revision
continue to run without disruption. Existing services that reference a
DELETE_IN_PROGRESS task definition revision can still scale up or down
by modifying the service's desired count.
You can't use a DELETE_IN_PROGRESS task definition revision to run new
tasks or create new services. You also can't update an existing service to reference a
DELETE_IN_PROGRESS task definition revision.
A task definition revision will stay in DELETE_IN_PROGRESS status until
all the associated tasks and services have been terminated.
When you delete all INACTIVE task definition revisions, the task
definition name is not displayed in the console and not returned in the API. If a task
definition revisions are in the DELETE_IN_PROGRESS state, the task
definition name is displayed in the console and returned in the API. The task definition
name is retained by Amazon ECS and the revision is incremented the next time you create
a task definition with that name.
