# Ulimit
<a name="API_Ulimit"></a>

The `ulimit` settings to pass to the container.

Amazon ECS tasks hosted on AWS Fargate use the default resource limit values set by the operating system with the exception of the `nofile` resource limit parameter which AWS Fargate 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.
