Hosts Plugin for Dokku

Plugin for setting etc/hosts entries within the app container

Warning: This plugin is under development and still only tested with the below dependencies

Useful when needing to set a host to be accessed within one app and for some reason using the IP address is not an option.

For example, when you have another dokku instance running at 199.10.32.3 and you access it via myapp.dokku.me mapped in your dev machine's /etc/hosts file:

# /etc/hosts
199.10.32.3 myapp.dokku.me

Requirements

Last time tested with the following:

Docker version 18.06.1-ce
Dokku version 0.12.13

Installation

cd /var/lib/dokku/plugins/available
git clone https://github.com/hablutzel1/dokku-hosts-plugin/ hosts
dokku plugin:enable hosts

Commands

$ dokku help
    hosts:add <app> <ip> <hostname>                 Sets <ip> and <hostname> for <app>
    hosts:list <app>                                Lists all custom hosts set for <app>
    hosts:remove <app> <hostname>                   Removes <hostname> from <app>
    hosts:removeall <app>                           Removes all hosts set for <app>

Simple usage

Make sure your app is running.

Add a ip/hostname to your app's etc/hosts

$ dokku hosts:add myapp 0.0.0.0 myhost.com

List currently set hosts

$ dokku hosts:list myapp

Advanced usage

Remove one entry

$ dokku hosts:remove myapp myhost.com

Remove all entries

$ dokku hosts:removeall myapp

TODO

Set configured hosts to every created app container, not just the ones existing after a deploy #1
