Support for dynamic ports all the way up to 65535.

[Molgaard78]

Is your feature request related to a problem? Please describe.

I have created my own container with SAMBA Active Directory Domain Controller and I want to use Microsoft Administrative Tools to manage the Domain Controller.

However: In order to use MMC to connect my Domain Controller it need to make a connection to a dynamic port in the range of 49152-65535, which it uses for RPC communication.

Alas: I found out that Kubernetes supports only dynamic ports in the range of 30000–32767.

As far as I recall that usual settings have been that anything running at port number < 1024 could only run as root while anything running on a port number above 1024 were fair game for everyone.

Therefore it is currently not possible to use any tools that uses RPC to communicate with Samba.

Describe the solution you'd like

Besides support for assigning any port to a container all the way up to port 65535, I would really hope to is a way to specify a port range as a single line, since adding 16383 ports to a yaml file by hand is:

• Way too tedious for anyone.
• Waste of space in the config file
• Eliminates overview about what is going on completely.

Is it something that has to be coordinated upstream with the main Kubernetes project?

And is it something you are willing to implement?
