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.
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
Adding a hostname to the $APP/VHOST file will enable it as a virtualhost for the application.
In addition, any hostname set that matches an associated ssl certificate will also be set as an ssl host. Note that if a hostname does not have a matching SSL host, then it will result in an erroring application.
For the moment, running `dokku url` on an app may not correctly display the current hostnames for said app.
I have done the first steps to get dokku running for other distros like
openSUSE. I have simply replaced the important places within the core
plugins with a check for DOKKU_DISTRO that gets exported by dokku
itself. It just replaces the apt-get and service start/restart/reload
functionality with the openSUSE counterparts.
This change makes Dokku start up the new container, run a set of checks
against it, and only switch traffic over to the new containers if all
checks complete successfully. No requests are dropped during the switch
over.
To specify checks, add a CHECKS file to the root of your project
directory. This is a text file with one line per check. Empty lines and
lines starting with # are ignored.
A check is a relative URL and may be followed by expected content from
the page, for example:
/about Our Amazing Team
Even if you don’t use any checks, this change will prevent downtime
during switching from old to new container.

HOME is not consistent if dokku is ran e.g. as root (for setup).
The DOKKU_ROOT variable will also make it possible to have the repositories stored in an arbitrary location (works-ish right now)
