Scheduler

The CipherTrust Data Security Platform Service can periodically run key rotation jobs in the background. These jobs can be:

  • Configured using the scheduler

  • Scheduled by creating a job configuration

A job configuration defines what job is run and when. Job configurations can be read, listed, updated, and deleted. Jobs are run after job configurations are created. The jobs that were run can also be listed.

This section provides examples of scheduler configurations using the ksctl utility. Refer to the CLI or API documentation for details.

Default Scheduler

The system-generated scheduler system_auto_key_rotation is disabled by default. When this scheduler is enabled, it runs every day at midnight, and rotates the keys with a rotation date less than the current time. To enable the scheduler, run:

ksctl scheduler configs modify key-rotation --id <ID> --disabled=false

Example

ksctl scheduler configs modify key-rotation --id e08708b9-c6f0-49f2-bbea-64bd6ee80779 --disabled=false

Keys are rotated based on the value configured in the scheduledRotationDate parameter. You can configure this value by setting the rotation-frequency-days parameter during key create or key modify request.

The value of the rotation-frequency-days parameter is defined in number of days, and should be greater than or equal to 0. The value of scheduledRotationDate is calculated based on key creation time + rotation-frequency-days.

When the scheduler runs, it only rotates the keys with a scheduledRotationDate before the current time.

For example, if rotation-frequency-days is set to 5 days for any key, the scheduler rotates that key every 5 days.

If rotation-frequency-days is set to "0", the key is not rotated. For more details, refer to Configuring Key Rotation Frequency Days.

Syntax (Key create)

ksctl keys create --name <key-name> --rotation-frequency-days <number-of-days>

Syntax (Key modify)

ksctl keys modify --name <key-name> --rotation-frequency-days <number-of-days>

Time Specification

The time that a job runs is described in the run-at parameter using the cron expression format: "* * * * *"

These five values indicate when the job should be executed. They are in order of minute, hour, day of month, month, and day of week.

The following table lists the accepted values:

Field Name Mandatory Allowed Values Allowed Special Characters
Minute Yes 0-59 * / , -
Hour Yes 0-23 * / , -
Day of month Yes 1-31 * / , -?
Month Yes 1-12 or JAN-DEC * / , -
Day of week Yes 0-6 or SUN-SAT * / , -?

Note

Month and Day of week field values are case insensitive. For example, "SUN", "Sun", and "sun" are equally accepted.

Note

Scheduler itself is a generic service, so it provides granularity of a minute. A job configuration should take the nature of operation information into consideration. For example, rotating the same set of multiple keys and backing up a database every minute are highly unlikely use cases.

Allowed Special Characters

The following table describes the use of special characters in the cron expression format:

Special Character Description
Asterisk * Indicate that the cron expression will match for all values of the field. For example, using an asterisk in the 5th field (month) would indicate every month.
Slash / Describe increments of ranges. For example, 3-59/15 in the 1st field (minutes) would indicate the 3rd minute of the hour and every 15 minutes thereafter.
Comma , Separate items of a list. For example, using "MON,WED,FRI" in the 5th field (day of week) would mean Mondays, Wednesdays, and Fridays.
Hyphen - Define ranges. For example, 9-17 would indicate every hour between 9am and 5pm inclusive, MON-WED would indicate Monday through Wednesday, and JAN-JUN would indicate every month from January through June.
Question mark ? Use instead of "*" for leaving either day-of-month or day-of-week blank. "?" means no specific value. For example, to run the job every 10th day of the month and not limit the job to a particular day of the week: "* * 10 * ?".

Permissions

Only users in the Key Admins group can manage Key Rotation job configurations.

Creating Job Configurations

To create a job configuration, run the command ksctl scheduler configs create <operation> --name <config-name> --run-at "<cron-expression-format>".

Refer to Scheduling Key Rotation for detailed descriptions of these options.

Viewing Existing Job Configurations

To view the list of job configurations, run the command ksctl scheduler configs list.

Example:

ksctl scheduler configs list

}

The output shows existing job configurations.

Viewing Details of Job Configurations

To view the details of a job configuration, run the command ksctl scheduler configs get --id "configID". Here, <configID> represents the ID of the configuration.

Example

ksctl scheduler configs get --id "fd0c27b8-a502-47cc-b6bc-4c1c6fbbe89a"
{
  "id": "fd0c27b8-a502-47cc-b6bc-4c1c6fbbe89a",

}

Modifying Job Configurations

Existing job configurations can be modified when needed. To modify a job configuration, run the command: ksctl scheduler configs modify <operation> --id "<configID>" <args>

Here,

  • <operation>: Operation can be backup or key-rotation.

  • <configID>: ID of the job configuration to be modified.

  • <args>: Parameters to modify.

        "change_state_after_time": 10,
        "replaced_key_state": "Deactivated"
    }
}

Manually Running Job Configurations

A scheduled configuration can be run manually when needed. To manually run a job configuration, run the command: ksctl scheduler configs run-now --id "<configID>"

Here, <configID> represents the ID of the configuration. The command creates a new job and waits for the job to be posted on the job queue. The "job_id" is returned if the job is posted within about 30 seconds.

Example:

ksctl scheduler configs run-now --id "e90cb2df-7df5-487a-ab5e-2c0ead7405c4"
{
  "job_id": "1e05dfb0-a5f9-48f6-afdf-406c368d2847",
  "job_config_id": "e90cb2df-7df5-487a-ab5e-2c0ead7405c4"
}

Disabling Job Configurations

You can disable an existing job configuration to temporarily prevent future job runs. To disable job configuration, run the command: ksctl scheduler configs modify <operation> --id "<configID>" --disabled

Here,

  • <operation>: Operation must be key-rotation.

  • <configID>: ID of the job configuration to be modified.

  • disabled: A boolean value indicated whether the job configuration is disabled, and will not run in the future.

To enable a disabled job configuration, run the command: ksctl scheduler configs modify <operation> --id "<configID>" --disabled=false

Deleting Job Configurations

Caution

This is a permanent operation. If you wish to temporarily suspend a scheduled job, you can disable it instead.

To delete a job configuration, run the command ksctl scheduler configs delete --id "<configID>". Here, <configID> is the ID of the job configuration to be deleted. The specified job configuration is deleted without any message.

After a configuration is deleted, it will no longer run jobs automatically.

Job Runs

A job is created and run automatically when a scheduler configuration is run manually (using run-now) or automatically at a schedule defined in the job configuration. You can view the results of jobs executed in the past, including status and error count.

Viewing Job Runs

To view the list of already run jobs for the logged in account, run the command ksctl scheduler jobs list.

ksctl scheduler jobs list
