Action

The action configuration allows you to automate your workflow by defining commands that are executed on an incoming event. Actions, similarly as communication platforms, use source bindings to define the event sources (command triggers) and executor bindings to run a given command.

The actions can be disabled and enabled using dedicated commands. See the Automated actions usage document for more details.

Predefined actions

There are two predefined actions available:

• describe-created-resource - describes a newly created resource,
• show-logs-on-error - prints logs on Pod/StatefulSet/DaemonSet/Deployment error.

Both of them are disabled by default. See details in the Syntax section.

Action output

The command output is sent to the communication platforms that define the same source bindings. If there are is no communication platform defined with the same source bindings, the action is still executed, but the output is ignored.

To learn more how to configure sources for communicators, read the communication documentation.

Command templates

Each action defines the command property which defines a command to be executed. It supports Go template syntax. The command template is rendered before actual execution.

The following variables are available:

• {{ .Event }} - the event object that triggered the action. See all available event properties in the event.go file.

There are multiple helper functions supported by the templating engine. To learn more, read the documentation on the slim-sprig library page.
