As briefly discussed in #1425, source the `common/functions` file via an
absolute path, rather than determining the relative path by using
`dirname`. 3rd-party plugins should follow suit and use the new
`$PLUGIN_PATH` convention too.
http://xip.io
xip.io is a service by Basecamp that provides a wildcard DNS service on the public internet. Any <ip address>.xip.io will return a DNS response for the IP address, same with <subdomain>.<ip address>.xip.io.
The domains plugin in dokku uses a regex to match IP4 and IP6 addresses in the VHOST file, and disables VHOST support if found. This PR changes those patterns to require that the VHOST entry **ends with** the IP address.
This is a gist where my VHOST setting is "127.0.0.1.xip.io" that demonstrates the original output, linked directly to the line from `plugins/domains/commands`: https://gist.github.com/anonymous/c529177f20b36beda80d#file-debug-log-L1373
The URL file is being rewritten on every deploy by `dokku deploy` and thus that file was incorrect. Instead, we just reuse the old logic from the nginx-vhosts plugin to handle creation of the VHOST file
This helps remove duplication and also ensures that all hosts have a proper setup after running `make copyfiles`
Note that this command is not exposed in help as it is not generally useful to developers
