Ok this is a bit janky: 'required' fields should have their value
initially set to '_' whilst fields that are "optional" should have
their value set to a sane default, such as an empty list in the case
This parser expects the following syntax to be used when serialising port
definitions - all elements are required.
Where the elements specifically are:
* name: represents the logical 'name' or 'reference' you want to use this port for.
Examples would be 'default' for the default service port, 'monitoring' for the
monitoring port, or something like 'mutualtls' for a secure channel. The actual
name is not important, but being a short, obvious reference to what it served on
that particular port is typically useful.
* port: the actual port number the container binds too when exposing network functionaltiy.
It goes without saying that the number must be between 1 and 65535 to form a
valid, usable port definition.
* protocol: the protocol used by the service being exposed by this port. This param is
used by nelson to know what should be done to the routing tables.
Here are some examples of usage, that are valid and accepted by this parser:
