CRD Configuration
The Kronos-Core Custom Resource Definition (CRD) allows users to define resource schedules for their Kubernetes clusters. The CRD manifest includes several fields that users can configure to customize their resource schedules. Here are the different fields in the manifest:
startSleep
type: string
usage: Specifies the start time for the sleep period in a 24-hour format (e.g., "13:02").
endSleep
type: string
usage: Specifies the end time for the sleep period in a 24-hour format (e.g., "22:41").
weekdays
type: string
usage: Specifies the weekdays on which the schedule should be applied using ISO8601 format. This field can contain individual weekdays seperated by "," and ranges (e.g., "2-5").
Using the ISO8601 means Kronos considers Monday as the first day of the week. Consequentially, week days are represented by the following numbers:
| Monday | Tuesday | Wednesday | Thursday | Friday | Sunday | Saturday |
|---|---|---|---|---|---|---|
| 1 | 2 | 3 | 4 | 5 | 6 | 7 |
timezone
type: string
usage: Specifies the timezone for the schedule using the IANA Timezone Database format (e.g., "Africa/Tunis").
holidays
type: array of objects
usage: Specifies any holidays during which the schedule should be adjusted. Each holiday is represented as an object with the following fields:
name
type: string
usage: The name of the holiday.
date
type: string
usage: The date or range of dates for the holiday in the format ISO8601 "YYYY-MM-DD" or "YYYY-MM-DD/DD/DD" if the holiday spans across multiple days.
includedObjects
type: array of objects
usage: Specifies the Kubernetes objects to include in the schedule. Each included object is represented as an object with the following fields:
apiVersion
type: string
usage: The API version of the Kubernetes object (e.g., "apps/v1").
kind
type: string
usage: The kind of Kubernetes object (e.g., "Deployment").
namespace
type: string
usage: The namespace of the Kubernetes object.
includeRef
type: string
usage: Optionally, the name of the specific object to include. If not defined, it will include all objects of the specified kind and ApiVersion.
excludeRef
type: string
