Install Oc Cluster Wrapper

To manage easier the cluster persistent, we are going to use oc cluster wrapper.

cd /home/administrador/oc
wget https://raw.githubusercontent.com/openshift-evangelists/oc-cluster-wrapper/master/oc-cluster

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

Configure iptables

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

- 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.

Cluster up

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

Cluster down

$ oc-cluster down

Use non-persistent cluster

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