Using Application Jobs


Application Jobs allow you to define and schedule regular tasks (shell commands) that will run against your Cloud 66 application's services (i.e inside your containers). Commands run using the sh shell by default. Each time an application job runs, it starts a new container from the service, executes the task and then destroys the container.

If you need to run a job on the underlying server, rather than the service, you should use Server Jobs instead.

Adding a new application job

To add a new application job:

  1. Open your application from the Dashboard
  2. Click Jobs in the left-hand nav
  3. Click on the New Application Job button
  4. Choose the service to which the job applies
  5. Give your new job a name
  6. Specify the command(s) you want to run
  7. Set a schedule for the job - you can use cron syntax for more control over your scheduling - or set it to run on demand
  8. Click Save

You will now see your new job listed in your application. You can edit it by clicking on the small downward arrow. Your run results (success, failure and any output) can be seen in real-time on the job detail page.

Using parameters

When you run a job you can pass it parameters (if it is written to accept them).


Jobs use a facility in the shell called positional parameters. Positional parameters are a series of special variables ($1, $2 ... $n) that contain the contents of the command line. Where n is greater than 9 using braces. For example, to refer to the 15th positional parameter, use the notation ${15}.

cp $1 $2
ls $1 $2 $3 $4 $5 $6 $7 $8 $9 ${10} ${11}

Default values

You can handle default value for the parameter with following notation: ${n:-YOUR_DEFAULT_VALUE}.

Example below cp file $1 to tmp directory by default

cp $1 ${2:-/tmp}

Passing parameters to a job

Since job is using positional parameters pass you arguments in order, eg: if you pass arg1 arg2, $1 would contain arg1 and $2 would contain arg2

You can also quote your argument if there is a space in the value.


Job commandcp $1 ${2:-/tmp}
Passing arguments via dashboard"log*.txt" tmp/logs
Passing arguments via Toolbelt--arg "log*.txt" -- arg tmp/logs
