Image registry

The default vSphere Cloud Provider does not support the ReadWriteMany access mode required by the Image Registry. As a result, the playbook for initial cluster deployment, site.yml, deploys an NFS virtual machine. A number of NFS shares are created and exported by the playbooks, and the Image Registry uses one of these NFS shares.

The number of NFS shares created by the playbooks can be customized using the variable num_nfs_shares in the configuration file group_vars/all/vars.yml. Only one share is required by the Image Registry service.
