### <a name="ulimit"></a> Set ulimits (--ulimit)
`--ulimit` is specified with a soft and hard limit as such:
`<type>=<soft limit>[:<hard limit>]`, for example:
```console
$ docker buildx build --ulimit nofile=1024:1024 .
```
> **Note**
>
> If you do not provide a `hard limit`, the `soft limit` is used
> for both values. If no `ulimits` are set, they are inherited from
> the default `ulimits` set on the daemon.
