Cockpit is also available as a minimalist's cluster visualizer [0].  If you
need help installing, try the Consulting Playbooks [1].

Yes, first time I deployed OpenShift I was very puzzled. But after
trying other Kubernetes deployment I think that works well and have a
lot of stuff that will help you to manage Kubernetes. 
First problem I see, you shared us a 3.6 documentation link but, if you
use Origin, the default behaviour is to deploy 3.7 docker images and it
could make the deployment fail.

OpenShift is an extension over Kubernetes. Do you want to use
Kubernetes? Just use "kubectl" client instead of "oc" client. 
Do you need something that OpenShift offers in the box like routes,
pipelines, ...? Use oc client.

Please, share us last ansible error and inventory file. Maybe we can
help you.

Everything is difficult until you learn it. ;-) 

If you finally decide not to using openshift, kubespray is my second
better friend ... but it is also ansible based and you will need to
install manually a lot of stuff that openshift offers you in the box.
IMHO OpenShift today is the better choice.

Generally that has been a responsibility of CloudForms / manageiq.  What
sorts of visualizations are you looking for?

By "use kubernetes" directly do you mean, "Using the kubernetes API's
directly?" or "Using an existing Kubernetes cluster?"  If the former, we
support all kubernetes GA level APIs, so you shouldn't be blocked there.
For the latter, most of the OpenShift security model requires protections
that are compiled into the kube binaries (multi-tenancy, protecting users
from escaping their namespaces), so today if you tried to run openshift on
top of raw kube you would not have any of the security model.

Some frustrations with OpenShift

[Alfredo Palhares]

Hello everyone,


I would like to share some of the frustations that I currently have with
openshift, which is making me not consider this a base to our container
infrastcture.
- No visualization of the cluster out of the box
 To me this seems a bit weird that there is no clear way of having
visualization of te cluster status out, i am strugggling following the
documentation
 , my
ansible playbook is breaking, and I have a simple 1 master and 3 nodes
setup.
- Not having the possibility to use kubernestes directly
Since I am running on metal, the idea of openshift would be more to get the
supporting services of and then using kubernetes deployments.
- The openshift-ansible is a bit confusing to me
Altough I see that on the newer versions it is getting better.


Just wanted to share some tough, I am not bashing on anything, I do still
think its a great platform, just getting into it is a bit hard if you are
not paying for support or deploying on the cloud.

Alfredo Palhares
