Scheduling containers

Levv allows you to schedule the scaling of your applications, reducing their footprint outside of business hours. You can scale the number of replicas down to avoid unnecessary consumption of ressources, and even scale them down to 0 to avoid any costs when your application is not running.

To configure the scheduling of your application, you can use the following labels:

LABEL	FORMAT	DESCRIPTION
io.levv.schedule.start_time	hh:mm	When your application scales up to # replicas (required)
io.levv.schedule.end_time	hh:mm	When your application scales down to # min_replicas (required)
io.levv.schedule.day_of_month	number, range	Which days of the month (default: *)
io.levv.schedule.month	number, name, range	Which months of the year (default: *)
io.levv.schedule.day_of_week	number, name, range	Which days of the week (default: *)
io.levv.schedule.timezone	timezone name	Timezone (default: UTC)
io.levv.schedule.min_replicas	number	The number of replicas (default: 0)

day_of_month, month and day_of_week labels use the traditional CRON syntax.

Example:

labels:
  io.levv.schedule.start_time: "9:00"               # START AT 9AM
  io.levv.schedule.end_time: "17:00"                # UNTIL 5PM
  io.levv.schedule.day_of_month: "1-7"              # RUN FROM THE 1ST OF THE MONTH UNTIL THE 7TH
  io.levv.schedule.month: "jan,feb"                 # RUN IN JANUARY AND FEBRUARY
  io.levv.schedule.day_of_week: "mon,wed,thu,fri"   # RUN ON MONDAY WEDNESDAY THURSDAY AND FRIDAY
  io.levv.schedule.timezone: "Europe/Brussels"      # TIMEZONE
  io.levv.schedule.min_replicas: 1                  # SCALE DOWN TO 1 REPLICA INSTEAD OF ZERO
