The sockaddr.Include and sockaddr.Exclude do not have "private" selector.

Hi @hairyhenderson,

I've noticed that the documentation mentions that the sockaddr.Exclude and sockaddr.Include support a "private" selector, but it does not seem to be the case, for instance:

$ gomplate -i '{{ sockaddr.GetAllInterfaces | sockaddr.Include "private" "" }}'
Error: template: <arg>:1:39: executing "<arg>" at <sockaddr.Include>: error calling Include: invalid include selector "private"

Which is correct as per the ifaddrs.go implementation.

To achieve this (somewhat), one would have to use the rfc selector with an appropriate numeric RFC code. Alternatively, we could send a Pull Request against go-sockaddr to add this include/exclude filter.

Would you like to send a Pull Request to update documentation?

I have opened a Pull Request at hashicorp/go-sockaddr#23 to add support for private to the include and exclude filters.

Hi @kwilczynski! Thanks for logging this issue. I'm really not sure why I documented private in there - probably a copy/paste error from Sort.

If you'd like to issue a PR to fix the doc, that'd be great!

From what I can see, doing sockaddr.Include "rfc" "6890" should accomplish what you're looking for. With Sort, private is really just a wrapper around the RFC 6890 comparator.

Hi @hairyhenderson,

No worries! Fix to the documentation coming right up!
