A Cron job service is like a Job service. It spins up the specific container on a given schedule.

​
Run command

When you create a service, you must provide appropriate Run command if your Dockerfile CMD doesn’t point at the job script.

​
Cron schedule

Specify a cron schedule like 5 4 * * *. Refer to https://crontab.guru/ for the syntax to specify your schedule.

​
Logs

You can see logs of the job via the in-built Grafana dashboard. Navigate to Monitor tab to login to Grafana dashboard. Within Grafana dashboard, filter to see app-services namespace logs. You can create any number of jobs in your environment.
