Provision a Deis Cluster on Rackspace

We'll mostly be following the CoreOS on Rackspace guide. You'll need to have a sane python environment with pip already installed (sudo easy_install pip).

Install supernova and its dependencies:

$ sudo pip install keyring
$ sudo pip install rackspace-novaclient
$ sudo pip install supernova

Configure supernova

Edit ~/.supernova to match the following:

[production]
OS_AUTH_URL = https://identity.api.rackspacecloud.com/v2.0/
OS_USERNAME = {rackspace_username}
OS_PASSWORD = {rackspace_api_key}
OS_TENANT_NAME = {rackspace_account_id}
OS_REGION_NAME = DFW (or ORD or another region)
OS_AUTH_SYSTEM = rackspace

Your account ID is displayed in the upper right-hand corner of the cloud control panel UI, and your API key can be found on the Account Settings page.

Set up your keys

Choose an existing keypair or generate a new one, if desired. Tell supernova about the key pair and give it an identifiable name:

$ supernova production keypair-add --pub-key ~/.ssh/deis.pub deis-key

Customize cloud-config.yml

Edit user-data and add a discovery URL. This URL will be used by all nodes in this Deis cluster. You can get a new discovery URL by sending a request to http://discovery.etcd.io/new.

Run the provision script

Run the Rackspace provision script to spawn a new CoreOS cluster. You'll need to provide the name of the key pair you just added. Optionally, you can also specify a flavor name.

$ cd contrib/rackspace
$ ./provision-rackspace-cluster.sh
Usage: provision-rackspace-cluster.sh <key pair name> [flavor]
$ ./provision-rackspace-cluster.sh deis-key

By default, the script will provision 3 servers. You can override this by setting DEIS_NUM_INSTANCES:

$ DEIS_NUM_INSTANCES=5 ./provision-rackspace-cluster.sh deis-key

Initialize the cluster

Once the cluster is up, get the hostname of any of the machines from EC2, set FLEETCTL_TUNNEL, and issue a make run from the project root:

$ export FLEETCTL_TUNNEL=23.253.219.94
$ cd ../.. && make run

The script will deploy Deis and make sure the services start properly.

Configure DNS

You'll need to configure DNS records so you can access applications hosted on Deis. See Configuring DNS for details.

Use Deis!

After that, register with Deis!

$ deis register deis.example.org:8000
username: deis
