# Set ip_forward to 1

# Setup docker to allow an "insecure" registry.
sed -i -e "s|\# INSECURE_REGISTRY='--insecure-registry'|INSECURE_REGISTRY='--insecure-registry 172.30.0.0/16'|" /etc/sysconfig/docker

# Start and enable docker.
systemctl daemon-reload
systemctl start docker
systemctl enable docker

# Check that it's in your path.
oc version

# Bring up the cluster.

# See that you can get pods (likely nothing there yet)

From Frank:

<fzdarsky> dougbtv, FYI, had to add those FW rules, otherwise pods wouldn't start.
<fzdarsky> Also, the 'sed' command no longer works. Needs echo '{"insecure-registries": ["172.30.0.0/16"] }' > /etc/docker/daemon.json instead.
