Templating

Templating is:

Simply a way to represent data in different forms.

Templating allows your playbook actions to work in context of a config or a component. Some actions, like exec action, can be templated using Go templates.

Example:

actions:
  - name: 'scale deployment'
    exec:
      script: kubectl scale --replicas={{.params.replicas}} --namespace={{.config.tags.namespace}} deployment {{.config.name}}

Context

Templates receive a context variable that contain details about the config or component it is running for. In addition, it also contains the optional params variable which contains the parameters passed to the playbook.

Field	Description	Schema
config	Config passed to the playbook	models.ConfigItem
component	Component passed to the playbook	models.Component
params	Parameters passed to the playbook	map[string]string
