I didn't even try CDK. It was just too aweful. I used `oc cluster up`. I'm a Linux guy with a Linux VM. I don't want to run some poor mans virt inside my VM. If my linux host was on GCE or AWS I couldn't. Thank god all of the CDK can be mostly scrapped with `oc cluster up`.

I had a clean F24 minimal VM
I built origin on another machine
I scp'd just oc to the VM
oc cluster up failed with a very good error message (docker was not running)
  resolved with:
    dnf install -y docker
    systemctl start docker
    systemtl enable docker
oc cluster up failed because I did not configure docker correctly
  resolved with:
    edit /etc/sysconfig/docker - add what oc cluster up told me to do
    systemctl restart docker
oc cluster up eventually completed and told me how to access the web ui
  I was unable to access the web UI
  resolved with:
    firewall-cmd --zone=public --add-port=8443/tcp --permanent
    firewall-cmd --reload
oc cluster up has a different default user (developer) than the CDK (apparently openshift-dev/devel)

I used the web console to create a new project called `helloworld-msa`
  we'll see what I broke by not doing things on the command line
  
Decide to look at Ansible. It says to make sure things are installed. But these names do not make it easy:
  git, ansible, and maven can be passed to dnf install, great
  "jdk" is not a package (although it does get picked up by the maven install)
  In Fedora you can't install npm with some terrible error message
    # dnf install npm

    Error: package npm-3.5.4-5.fc24.noarch requires nodejs(engine), but none of the providers can be installed
  But `dnf install nodejs` gets one an npm binary, so hopefully that's enough?

First, edit the vars.yaml file to define the 'workdir' variable and set the absolute path where you want to "git checkout" the source code of the microservices.
  I don't even know what this means, is it supposed to be related to where I already did a git clone? I just uncommented the variable.
  
I changed 'openshift' since `oc cluster up` is running on my node, not some hard coded IP in a VM
The 'domain' I have no idea about... but I changed it's ip as well (same as 'openshift')

`ansible-playbook helloworld-msa.yml` failed because I didn't have `oc` in my path
  sudo cp oc /usr/bin/

`Verify oc version` hard codes a check for `oc v3.2` - So this breaks in origin and will break when we release 3.3

Now the user came back to bite me. Ansible hard coded stuff. The mapping from CDK->`oc cluster up`
  openshift-dev/devel -> developer/developer
I've left admin/admin but I think that's going to bite eventually
  admin/admin -> system:admin/???
  
Actually OC cluster up left me with a busted cluster :-( No registry
  cesar wong flushed the iptables rules and restarted the clsuter, registry came up
  he blamed https://github.com/openshift/origin/issues/10139 (unresolved at this time)

I note that these are all using the `docker` build strategy. The one strategy we call unsafe and don't allow online.

Now one of the builds fails (bonjour-1):

No clue, I'm going to cheat off someone else's gist.
And no one else had this problem.
I'm stuck for this night.
