Delayed Actions

Delay

This example demonstrates how to create a playbook that restarts a Kubernetes Pod and introduces a delay before checking the status of the Pod to ensure it has restarted properly.

restart-pod-with-delay.yaml
apiVersion: mission-control.flanksource.com/v1
kind: Playbook
metadata:
  name: restart-pod
spec:
  description: Restarts a Kubernetes Pod and checks its status after a delay
  configs:
    - type: Kubernetes::Pod
  actions:
    - name: Restart the Pod
      exec:
        script: kubectl delete pod {{.config.name}} -n {{.config.tags.namespace}}
    - name: Wait for Pod to restart
      delay: '30s'
    - name: Check Pod status
      exec:
        script: kubectl get pod {{.config.name}} -n {{.config.tags.namespace}} -o jsonpath='{.status.phase}'

This example

1. Deletes the specified Kubernetes Pod to restart it.
2. Introduces a delay of 30 seconds to allow the Pod to restart.
3. Checks the status of the Pod to ensure it has restarted properly.

Dynamic Delay

This example demonstrates how to create a playbook that restarts a Kubernetes Pod and introduces a delay based on the readinessProbe.initialDelaySeconds before checking the status of the Pod to ensure it has restarted properly.

restart-pod-with-dynamic-delay.yaml
apiVersion: mission-control.flanksource.com/v1
kind: Playbook
metadata:
  name: restart-pod-dynamic-delay
spec:
  description: Restarts a Kubernetes Pod and checks its status after a dynamic delay
  configs:
    - type: Kubernetes::Pod
  actions:
    - name: Restart the Pod
      exec:
        script: kubectl delete pod {{.config.name}} -n {{.config.tags.namespace}}
    - name: Wait for Pod to restart
      delay: '{{.config.config.spec.containers[0].readinessProbe.initialDelaySeconds}}s'
    - name: Check Pod status
      exec:
        script: kubectl get pod {{.config.name}} -n {{.config.tags.namespace}} -o jsonpath='{.status.phase}'

This example

1. Deletes the specified Kubernetes Pod to restart it.
2. Introduces a delay based on the initialDelaySeconds to allow the Pod to restart.
3. Checks the status of the Pod to ensure it has restarted properly.
