You will likely want to automate some tasks regarding your `docker` infrastructure.
That's why the `kiwi-cron` images package a current `docker-cli` you can just mount your `docker.sock` in its containers and use `docker` commands normally.
## Time Zones
`kiwi-cron` images include the `tzdata` package and automatically handle `/etc/localtime` on startup. By default, "Etc/UTC" is set as the container time zone.
To use a different time zone, change the container environment variable `TZ` to your liking, e.g. "Europe/Berlin".
## Simple jobs
On startup, `kiwi-cron` checks for possible job files in the `/kiwi-cron` directory structure.

For each subdirectory, a random valid cron schedule is generated, so that:
- `/kiwi-cron/hourly` runs once every hour (random minute)
- `/kiwi-cron/daily` runs once every day (random nighttime value)
- `/kiwi-cron/daily` runs once every day (random nighttime value between 9 pm and 3 am)
- `/kiwi-cron/weekly` runs once every weekend (random nighttime value on Saturday or Sunday)
- `/kiwi-cron/monthly` runs once every month (random nighttime value on a random day)
- `/kiwi-cron/yearly` and `/kiwi-cron/annually` runs once a year (random nighttime value on a random day in January or February)
- `/kiwi-cron/monthly` runs once every month (random nighttime value on a random day <= 28)
- `/kiwi-cron/yearly` and `/kiwi-cron/annually` runs once a year (random nighttime value on a random day <= 28 in January or February)
Cron schedules are regenerated once on each startup, only for directories that have files.

Directories like `/kiwi-cron/every/5_minutes` will run scripts every 5 minutes.
`kiwi-cron` picks up on that format and generates valid `cron` schedules on startup.
You can define schedules to be run every N minutes, hours, days, or months by creating the corresponding directories.

Scheduling for every N weeks (or years) doesn't work that way; jobs in those directories will instead be run every week (or every year).
