ECS / Client / execute_command

execute_command#

ECS.Client.execute_command(**kwargs)#

Runs a command remotely on a container within a task.

If you use a condition key in your IAM policy to refine the conditions for the policy statement, for example limit the actions to a specific cluster, you receive an AccessDeniedException when there is a mismatch between the condition key value and the corresponding parameter value.

For information about required permissions and considerations, see Using Amazon ECS Exec for debugging in the Amazon ECS Developer Guide.
