dokku-dockerfile

Deploy your applications via Dockerfile, while keeping your project root clean of auxiliary files.

Installation

sudo dokku plugin:install https://github.com/mimischi/dokku-dockerfile.git

Commands

dockerfile:set    <app> <path/to/Dockerfile> Set custom path to Dockerfile
dockerfile:unset  <app>                      Unset custom path to Dockerfile
dockerfile:report <app>                      Report custom path to Dockerfile

Usage

Dokku will look for a Dockerfile in the project root, when building a non-buildpack application. Depending on the projects structure, it's desirable to keep deployment specific files in subdirectories. This plugin points Dokku to the relative path of the Dockerfile.

To deploy an application with a directory structure as shown below, one would use the following command:

dokku dockerfile:set <app> docker/dokku/Dockerfile

Example project structure

.
├── app
│   ├── [...]
├── docker
│   ├── dokku
│   │   ├── Dockerfile
│   │   ├── [...]
│   └── local
│       ├── Dockerfile-dev
├── docker-compose.yml
└── README.md

Behind the scenes

During the deploy process, this plugin copies the Dockerfile specified path to the projects root, enabling Dokku to build it.
