# UlimitProperty

The ``ulimit`` settings to pass to the container.

Amazon ECS tasks hosted on FARGATElong use the default resource limit values set by the operating system with the exception of the ``nofile`` resource limit parameter which FARGATElong overrides. The ``nofile`` resource limit sets a restriction on the number of open files that a container can use. The default ``nofile`` soft limit is ``65535`` and the default hard limit is ``65535``.
 You can specify the ``ulimit`` settings for a container in a task definition.
