Provision a Deis Controller on Rackspace

1. Install knife-rackspace with gem install knife-rackspace or just bundle install from the root directory of your deis repository:

   $ cd $HOME/projects/deis
   $ gem install knife-rackspace
   Fetching: knife-rackspace-0.9.0.gem (100%)
   Successfully installed knife-rackspace-0.9.0
   1 gem installed
   Installing ri documentation for knife-rackspace-0.9.0...
   Installing RDoc documentation for knife-rackspace-0.9.0...

2. Export your Rackspace credentials as environment variables and edit knife.rb to read them:

   $ cat <<'EOF' >> $HOME/.bash_profile
   export RACKSPACE_USERNAME=<your_rackspace_username>
   export RACKSPACE_API_KEY=<your_rackspace_api_key>
   source $HOME/.rackspacerc
   EOF
   $ cat <<'EOF' > $HOME/.rackspacerc
   export OS_AUTH_URL="https://identity.api.rackspacecloud.com/v2.0/"
   export OS_USERNAME=$RACKSPACE_USERNAME
   export OS_PASSWORD=$RACKSPACE_API_KEY
   export OS_TENANT_NAME=$RACKSPACE_USERNAME
   export OS_TENANT_ID=<your_rackspace_tenant_id>
   export OS_REGION_NAME=<your_rackspace_region_name>
   export OS_AUTH_SYSTEM="rackspace"
   EOF
   $ source $HOME/.bash_profile
   $ source $HOME/.rackspacerc
   $ cat <<'EOF' >> $HOME/.chef/knife.rb
   knife[:rackspace_api_username] = "#{ENV['RACKSPACE_USERNAME']}"
   knife[:rackspace_api_key] = "#{ENV['RACKSPACE_API_KEY']}"
   knife[:rackspace_ssh_keypair]   = "deis"
   knife[:rackspace_region]        = #{ENV['OS_REGION_NAME']}
   EOF
   $ knife rackspace server list
   Instance ID  Name  Public IP  Private IP  Flavor  Image  State

3. Now you can follow the standard deis setup:

bundle install # Installs gem files like the knife tool
berks install # Downloads the relevant cookbooks
# '--ssl-verify' is only needed when using a self-hosted Chef Server
# hint: you can also set that at $HOME/.berkshelf/config.json
berks upload [--ssl-verify=false] # Upload the cookbooks to the Chef Server

4. Prepare a new server

   1. Create a server named deis-prepare-image using the Ubuntu 12.04 LTS image, performance1-2, 1GB performance server

   2. SSH in as root with the password shown

   3. Install the 3.11 kernel with: apt-get update && apt-get install -yq linux-image-generic-lts-saucy linux-headers-generic-lts-saucy && reboot

   4. After reboot is complete, SSH back in as root and uname -r to confirm kernel is 3.11.0-17-generic

   5. Run the prepare-node-image.sh script to optimize the image for fast boot times

      $ ssh root@ip-address 'bash -s' < contrib/rackspace/prepare-node-image.sh

      ...

5. Create a new image from the deis-prepare-image server named deis-node-image.

   1. In the server list in the Control Panel click the action cog for deis-prepare-image
   2. Select "Create New Image" name that image deis-node-image
   3. (optionally) Distribute the image to other regions
   4. (optionally) Create/update your Deis flavors to use your new images

6. Make sure to add the deis-controller client object and the <your_username>-validator usernames to the Chef 'admins' group.

7. Back on your machine with deis cloned and the deis CLI installed, run the provisioning script to create a new Deis controller:

   • Change <region> to match the region your image is in (we will add SYD and HKG as soon as performance flavors are available there):

     • dfw
     • ord
     • iad
     • lon

     $ cd deis
     $ bundle install # if you have not already done so
     $ ./contrib/rackspace/provision-rackspace-controller.sh <region>
