This reverts commit fdcc5d68a2.
Unfortunately, this requires us to move exports to the bottom.
This in turn causes circular dep issues and also access of
exports.GLOBAL_VAR in the global context
re-creating nginx configs is only needed in 3 cases:
* provider changes. we create a rebuild file for this
* nginx config is somehow corrupt by external changes. user can click ui button
on startup, dashboard also always creates the nginx configs. so it's always up to provide the button
9c8f78a059 already fixed many of the cert issues.
However, some issues were caught in the CI:
* The TLS addon has to be rebuilt and not just restarted. For this reason, we now
move things to a directory instead of mounting files. This way the container is just restarted.
* Cleanups must be driven by the database and not the filesystem . Deleting files on disk or after a restore,
the certs are left dangling forever in the db.
* Separate the db cert logic and disk cert logic. This way we can sync as many times as we want and whenever we want.
An issue was that mail container was not getting refreshed with the up to
date certs. The root cause is that it is refreshed only in the renewCerts()
cron job. If cert renewal was caused by an app task, then the cron job will
skip the restart (since cert is fresh).
The other issue is that we keep hitting 0 length certs when we run out of disk
space. The root cause is that when out of disk space, a cert renewal will
cause cert to be written but since it has no space it is 0 length. Then, when
the user tries to restart the server, the box code does not write the cert again.
This change fixes the above two including:
* To simplify, we use the fallback cert only if we failed to get a LE cert. Expired LE certs
will continue to be used. nginx is fine with this.
* restart directory as well on renewal
