Docker Service task
To add this add-in, simply click on the + button on the add-ins menu of your stack page, which will show you a variety of add-ins for your stack.
This add-in allows you to schedule the execution of tasks (shell commands) on your Docker services. You can set the timing of the job in either minutes, hours, a daily, weekly and monthly time, as well as on demand (under the hood, scheduled jobs are run as cronjobs on your server). The command runs against the sh shell by default - if the task fails, try using
/bin/bash -c 'command'.
Each time it runs, it starts a new container from the service you select, executes the task and destroys the container. Your run results (success, failure and any output) can be seen in real-time on the job detail page.
