Installation

Follow the steps below to install your own Deis platform on EC2. To complete the installation process, you will need Git, RubyGems, Pip, the Amazon EC2 API Tools, EC2 Credentials, and a Chef Server with a working Knife client.

Please note: Deis is still under active development. It should not yet be used in production.

1. Clone the Deis Repository

$ git clone https://github.com/opdemand/deis.git
$ cd deis

2. Configure the Chef Server

Deis requires a Chef Server. Sign up for a free Hosted Chef account if you don’t have one. You’ll also need a Ruby runtime with RubyGems in order to install the required Ruby dependencies.

$ bundle install    # install ruby dependencies
$ berks install     # install cookbooks into your local berkshelf
$ berks upload      # upload cookbooks to the chef server

3. Provision a Deis Controller

The Amazon EC2 API Tools will be used to setup basic EC2 infrastructure. The Knife EC2 plugin will be used to bootstrap the controller.

$ contrib/provision-ec2-controller.sh
usage: contrib/provision-ec2-controller.sh [region]
$ contrib/provision-ec2-controller.sh us-west-2
Creating security group: deis-controller
+ ec2-create-group deis-controller -d 'Created by Deis'
GROUP   sg-7c40f317     deis-controller Created by Deis

4. Install the Deis Client

Install the Deis client using Pip. Registration will discover SSH keys automatically and use the standard environment variables to configure the EC2 provider.

$ sudo pip install deis
$ deis register http://my-deis-controller.fqdn
username: myuser
password:
email: myuser@example.com
Registered myuser
Logged in as myuser

Found the following SSH public keys:
1) id_rsa.pub
Which would you like to use with Deis? 1
Uploading /Users/myuser/.ssh/id_rsa.pub to Deis... done

Found EC2 credentials: AKIAJTVXXXXXXXXXXXXX
Import these credentials? (y/n) : y
Uploading EC2 credentials... done

5. Create & Scale a Formation

Find an application you’d like to deploy, or clone an example app. Change into the application directory and use deis create to initialize a new formation in a specific EC2 region. Use the deis layers:scale command to provision nodes that will be dedicated to this formation.

$ cd <my-application-repo>
$ deis create --flavor=ec2-us-west-2
Creating formation... done, created peachy-waxworks
Git remote deis added

Creating runtime layer... done
Creating proxy layer... done

Use deis layers:scale proxy=1 runtime=1 to scale a basic formation

$ deis layers:scale proxy=1 runtime=1
Scaling layers... but first, coffee!
...done in 232s

Use `git push deis master` to deploy to your formation

6. Deploy your Application

Use git push deis master to deploy your application. Deis will automatically deploy Docker containers and configure Nginx proxies to route requests to your application.
