Option for adding 127.0.0.1 entries

[crussell52]

In some cases, it is preferable to connect to the vagrant machine using localhost and forwarded ports.

(One such case is when on a securely configured VPN which sucks up all LAN traffic.)

In these cases, it would be very convenient if there was an plugin option enabling localhost entries.

config.hostsupdater.localhost_entries = true

It may also make sense to add a similar flag to turn off private network IPs. That way, the following configuration would result in entries for only localhost.

config.vm.network "private_network", ip: "172.21.9.9"
config.vm.hostname = "www.example.com"

config.hostsupdater.localhost_entries = true
config.hostupdate.private_network_entries = false

This would be more convenient than adding the "skip" option to the private network, especially in cases where there are multiple IPs configured.

@crussell52 I worry about the localhost getting polluted. Is this a worry for anyone else?

What about using vagrant's forwarded ports?

[crussell52]

One of the work-arounds I had for the VPN-scenario is to use localhost:8000 in my browser for reaching the application. However, I am working on a multi-tenant site where the subdomain is meaningful (part of the resolving usernames). This makes the ability to use subdomains paramount.

In reality, I would still be using port forwarding in conjunction with the hosts rewriting to reach the application via: someclient.mydomain.local:8000 where someclient.mydomain.local was mapped to localhost.

I'm wouldn't be over-concerned about localhost becoming polluted since hostsupdater does such a great job of cleaning up after itself. Only boxes that were running (and configured) would have registered localhost entries.

What I don't know is what the expected behavior would be if both private_network_entries was turned on and localhosts_entries was turned on. I guess it would be similar to cases where two private_network IPs are present?
