Instead of Cron jobs you could schedule it directly into HA using automation and shell commands. I have tons of these that I use for various purposes and doing it in HA has the added benefit of being able to set conditions on which scripts to execute and when. For example, here is what I use to truncate my log every hour:

shell_commands.yaml:

shell_rotate_log: '/config/logreset.sh'

automation:

alias: 'Schedule: Clear Logs Each Hour'
description: ''
trigger:
  - platform: time_pattern
    hours: /1
    minutes: '59'
condition: []
action:
  - service: shell_command.shell_rotate_log
    data: {}
mode: single
