Command Lists	2	This page tells you how to get started with Backy.

Command lists are for executing commands in sequence and getting notifications from them.

The top-level object key can be anything you want but not the same as another.

Lists can go in a separate file. Command lists should be in a separate file if:

1. key 'cmd-lists.file' is found
2. hosts.yml or hosts.yaml is found in the same directory as the backy config file

  test2:
    name: test2
    order:
      - test
      - test2
    notifications:
      - mail.prod-email
      - matrix.sysadmin
    cron: "0 * * * * *"

key	description	type	required
order	Defines the sequence of commands to execute	[]string	yes
getOutput	Command(s) output is in the notification(s)	bool	no
notifications	The notification service(s) and ID(s) to use on success and failure. Must be service.id. See the notifications documentation page for more	[]string	no
name	Optional name of the list	string	no

Order

The order is an array of commands to execute in order. Each command must be defined.

order:
  - cmd-1
  - cmd-2

getOutput

Get command output when a notification is sent.

Is not required. Can be true or false. Default is false.

Notifications

An array of notification IDs to use on success and failure. Must match any of the notifications object map keys.

Name

Name is optional. If name is not defined, name will be the object's map key.

Cron mode

Backy also has a cron mode, so one can run backy cron and start a process that schedules jobs to run at times defined in the configuration file.

Adding cron: 0 0 1 * * * to a cmd-lists object will schedule the list at 1 in the morning. See https://crontab.guru/ for reference.

{{% notice tip %}} Note: Backy uses the second field of cron, so add anything except * to the beginning of a regular cron expression. {{% /notice %}}
