Templating

Templating is:

Simply a way to represent data in different forms.

Templating allows your playbook actions to work in context of a config, health check or a component.

Example:

scale-deployment.yaml
apiVersion: mission-control.flanksource.com/v1
kind: Playbook
metadata:
  name: scale-deployment
spec:
  description: Scale deployment
  configs:
    - type: Kubernetes::Deployment
      tags:
        environment: staging
  parameters:
    - name: replicas
      label: The new desired number of replicas.
  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	`ConfigItem`
`component`	Component passed to the playbook	`Component`
`check`	Canary Check passed to the playbook	`Check`
`params`	User provided parameters to the playbook	`map[string]string`
