Intermediarily take over dokku application to not have to stop nginx

[almereyda]

Can we imagine a scenario where the plugin disables the desired dokku application, takes its domain name, runs everything in a container attached to this and reverts all environment changes once done?

I think we could solve this in two ways:
Use the webroot feature in lets encrypt - create a new static server and temporary point the dokku application towards this. Or we could wait for the offical nginx plugin to be stable. I'm leaning towards waiting for letsencrypt to support nginx. But if you have a better solution or got the time to rewrite the plugin to support webroot a PR is more than welcome :)
