Override Default Application Values

You can override default application values using the commands described in this section.

Procedure

1. View existing values.

   ~(keystone_admin)]$ system helm-override-show ptp-notification
   ptp-notification notification
   

2. Create a yaml file and update the fields that require Helm overrides.

   cat ~/override.yaml
   ptptracking:
    device:
      holdover_seconds: 25
      poll_freq_seconds: 2
   

3. Apply the values.

   Application values can be added by the user and applied, using the following commands.

   Note

   The application could be in the “uploaded” or “applied” state.

   ~(keystone_admin)]$ system helm-override-update ptp-notification ptp-notification notification -–values <<override.yaml>>
   

   ~(keystone_admin)]$ system application-apply ptp-notification
