Deis can deploy any application or service that can run inside a Docker container. In order to be scaled horizontally, applications must follow Heroku’s twelve-factor methodology and store state in external backing services.
For example, if your application persists state to the local filesystem – common with content management systems like Wordpress and Drupal – it cannot be scaled horizonally using
Fortunately, most modern applications feature a stateless application tier that can scale horizontally inside Deis.
Before deploying an application, users must first authenticate against the Deis Controller.
$ deis login http://deis.example.com username: deis password: Logged in as deis
For Vagrant clusters:
deis login http://deis.local3.deisapp.com
Deis supports three different ways of building applications:
Heroku buildpacks are useful if you want to follow Heroku’s best practices for building applications or if you are porting an application from Heroku.

Dockerfiles are a powerful way to define a portable execution environment built on a base OS of your choosing.

Deploying a Docker image onto Deis allows you to take a Docker image from either a public or a private registry and copy it over bit-for-bit, ensuring that you are running the same image in development or in your CI pipeline as you are in production.
