### Interactive:
openshift-install create install-config --dir rhte

### Confirm install-config.yaml and drop replica count for control/compute:
cat ./rhte/install-config.yaml
sed -i 's/replicas: 3/replicas: 1/' ./rhte/install-config.yaml
sed -i '6s/.*/  platform: {"openstack": {"type": "m1.large"}}/' ./rhte/install-config.yaml
cat ./rhte/install-config.yaml

openshift-install create ignition-configs --dir rhte
openshift-install create manifests  --dir ./rhte

ls ./rhte/manifests/

### Kickoff install:
time openshift-install --log-level=debug create cluster --dir rhte


### Tunnel with sshuttle for full experience (update with cluster ID):
sshuttle --dns -r [email protected] 172.16.0.1/24 192.168.122.0 --to-ns=192.168.122.3

### Scale Up:
oc get machinesets -n openshift-machine-api | grep -i rhte | awk '{system("oc scale machinesets " $1 " --replicas=2 -n openshift-machine-api")}'
### Scale Down:
oc get machinesets -n openshift-machine-api | grep -i rhte | awk '{system("oc scale machinesets " $1 " --replicas=1 -n openshift-machine-api")}'
