Enable clair components:

• Set it to true if you wish to install the clair components(image vulnerability scanning) on single machine, false otherwise.

Backup Target Location[Only applicable on Local VM deployment]:

• Set a directory location to store the cloud backups taken every night.

Note:

• It is recommended to use a directory which is mounted on a separate disk to ensure the safety of backups in case of a disaster.

• The backup directory used should support mount & unmount operations as it will be used to restore the backups in case of a disaster.

List of IPs:

Info: Please configure static IPs to the machines and configure those IPs in the configuration file.

• In the case of single machine installation, configure the IP only in the single_vm_ip field and leave the other IPs as it is.
