Action-Provider

Depending on the action that should be executed in course of a remediation (or operational), a corresponding action-provider must be deployed. This action-provider receives a Keptn event, performs its action, and notifies Keptn about the execution.

To plug-in an action-provider into a remediation, the remediation config must be extended by an action supported by the provider. Consequently, Keptn - as control plane and responsible for orchestrating the remediation - can send out the proper event for the action-provider.

Unleash Action-Provider

This action-provider toggles the feature flag specified by the key-value map in the value property. While the key declares the name of the feature toggle, the value specifies the target setting.

• Action that needs to be added to actionsOnOpen in the remediation config:

- name: Toogle feature flag
  action: featuretoggle
  description: Toggle feature flag EnablePromotion from ON to OFF.
  value: 
    EnablePromotion: off

• To install the action-provider for Unleash, execute:

kubectl apply -f kubectl apply -f https://raw.githubusercontent.com/keptn-contrib/unleash-service/0.1.0/deploy/service.yaml

Note: The referenced service.yaml already contains the required distributor.

Helm Action-Provider

This action-provider increases the ReplicaSet of a Kubernetes deployment by the number defined by the value increment.

• Action that needs to be added to actionsOnOpen in the remediation config:

- name: Scaling ReplicaSet by 1
  description: Scaling the ReplicaSet of a Kubernetes Deployment by 1
  action: scaling
  value: "1"

• The helm-service is installed by default.
