How to get the argo workflow age in seconds using kubectl command


Is there a way to fetch a specific argo workflow age in seconds using kubectl command?

I've a requirement for comparing the argo workflow age. If the workflow age is greater than 24 hours I need to terminate the workflow.


Solution

  • You should probably use Argo Workflow's built-in, declarative timeout feature:

    spec:
      activeDeadlineSeconds: 86400
    

    That will fail the workflow if it takes over 24 hours. To actually delete the workflow, set a TTL policy.

    ttlStrategy:
      secondsAfterCompletion: 60
    

    The cost optimizations docs have some other notes which will be helpful when designing your cleanup strategy.

    I can never resist a good jq challenge, so here's a script-based alternative:

    WORKFLOW_NAME=something
    
    if kubectl get wf -n argo "$WORKFLOW_NAME" -ojson | jq --exit-status 'now - (.metadata.creationTimestamp | fromdateiso8601) > (24*60*60)'; then
      kubectl delete wf -n argo "$WORKFLOW_NAME"
