 | port mappings | Pass mapping from ports on the host to ports in the container network namespace. | Operators can ask runtimes to pass port mapping information to plugins, by setting the following in the CNI config <pre>"capabilities": {"portMappings": true} </pre> Runtimes should fill in the actual port mappings when the config is passed to plugins. It should be placed in a new section of the config "runtimeConfig" e.g. <pre>"runtimeConfig": {<br />  "portMappings" : [<br />    { "hostPort": 8080, "containerPort": 80, "protocol": "tcp" },<br />    { "hostPort": 8000, "containerPort": 8001, "protocol": "udp" }<br />  ]<br />}</pre> | none | none |
 
 For example, the configuration for a port mapping plugin might look like this to an operator (it should be included as part of a [network configuration list](https://github.com/containernetworking/cni/blob/master/SPEC.md#network-configuration-lists).
