The value of the `hostPortRange` is set as follows: - For containers in a task with the `awsvpc` network mode, the `hostPortRange` is set to the same value as the `containerPortRange`. This is a static mapping strategy. - For containers in a task with the `bridge` network mode, the Amazon ECS agent finds open host ports from the default ephemeral range and passes it to docker to bind them to the container ports. - The `containerPortRange` valid values are between 1 and 65535. - A port can only be included in one port mapping per container. - You cannot specify overlapping port ranges. - The first port in the range must be less than last port in the range. - Docker recommends that you turn off the docker-proxy in the Docker daemon config file when you have a large number of ports. For more information, see [Issue #11185](https://github.com/moby/moby/issues/11185) on the Github website.
