oc-cluster up devonfw-shop-floor --public-hostname X.X.X.X

We must create iptables rules to allow traffic from other machines.

```diff
- The next commands it's to let all traffic, don't do it on a real server.

- $ iptables -F
- $ iptables -X
- $ iptables -t nat -F
- $ iptables -t nat -X
- $ iptables -t mangle -F
- $ iptables -t mangle -X
- $ iptables -P INPUT ACCEPT
- $ iptables -P OUTPUT ACCEPT
- $ iptables -P FORWARD ACCEPT
```

= How to use Oc Cluster Wrapper

With oc cluster wrapper we could have different clusters with different context.

$ oc-cluster up devonfw-shop-floor --public-hostname X.X.X.X
----

== Cluster down

[source,Shell]
----
$ oc-cluster down
----

== Use non-persistent cluster

[source,Shell]

oc cluster up --image openshift/origin --public-hostname X.X.X.X --routing-suffix apps.X.X.X.X.nip.io
