Box 1: createOptions
Every module has a settings property that contains the module image, an address for the container image in a container registry, and any createOptions to configure the image on startup.
Box 2: portbindings
Use the PortBindings setting in the HostConfig group of the Docker container create options to map the exposed port in the module to a port on the host device.
For example, if you exposed port 8080 inside the module and want to map that to port 80 of the host device, the create options in the template.json file would look like the following example:
"createOptions": {
"HostConfig": {
"PortBindings": {
"8080/tcp": [
{
"HostPort": "80"
}
]
}
}
}
