To implement a remediation sequence, you must:
remediationsequence in the project’s shipyard
The definition of a remediation sequence is done in the project’s Shipyard.
Example: Simple shipyard file with a remediation sequence in a single stage
apiVersion: "spec.keptn.sh/0.2.3" kind: "Shipyard" metadata: name: "shipyard-sockshop" spec: stages: - name: "production" sequences: - name: "remediation" triggeredOn: - event: "production.remediation.finished" selector: match: evaluation.result: "fail" tasks: - name: "get-action" - name: "action" - name: "evaluation" triggeredAfter: "10m" properties: timeframe: "10m"
Example of a remediation configuration:
apiVersion: spec.keptn.sh/0.1.4 kind: Remediation metadata: name: serviceXYZ-remediation spec: remediations: - problemType: Response time degradation actionsOnOpen: - action: scaling name: Scaling ReplicaSet by 1 description: Scaling the ReplicaSet of a Kubernetes Deployment by 1 value: "1"
