DemoCluster  A directory with your cluster name that contains the following files  for the cluster: cluster-configuration.yaml  - A file indicates that the cluster  configurations in the ssc4icp-config.yaml file are applied  successfully. quotagroup-symlink.yaml  - A file contains details of storage  containers, quotagroups and device names if you specify  GlusterFS configurations in the ssc4icp-config.yaml file. For more  information, see Deploying GlusterFS. ipsec.conf  - A file that contains the network topology of the  cluster. ipsec.secret  - A file that contains a randomly generated  Pre-Shared-Key (PSK) that will be used as an authorization token  to the IPSec network. An ssh key pair  ssh_key  and  ssh_key.pub  files that provide SSH  access for the IBM Cloud Private installer to all the cluster nodes.  In order for the IBM Cloud Private installer to access your master  or boot node over SSH and also to use the generated SSH key,  you must follow the instructions in the  Before you begin  section of  Deploying IBM Cloud Private : https://www.ibm.com/support/knowledgecenter/en/SSUPZ7_1.1 .0.3/topics/install_icp.html File/Directory name Description The following  cluster-configuration.yaml  example file (Example 3-6 on page 90) was  generated based on the cluster configuration that is specified in our  ssc4icp-config.yaml  file.
