# This script is used to create and start a new cluster as well as start an existing cluster.

# Starts an OpenShift cluster using Docker containers, provisioning a registry, router, initial templates, and a default project.

# Data and config is preserved between restarts with the --use-existing-config flag and --host-data-dir argument.

# A public hostname is specified for the server with the --public-hostname argument.

# A custom routing suffix is specified using the --routing-suffix argument.
# This is to allow dynamic host names to be created for routes.

# This script also adds one user to cluster-admin role.

# You can copy or edit config.sh configuration file. This way you can install more then one cluster. However, only one cluster can run at a time.

# You can run 2.install.certificate.sh to install your server's certificate and private key into cluster.
# Then you will be able to access the web console at https://your-domain:8443/console .
