Retry Backoff

Note

This example is a replication of an Argo Workflow example in Hera. The upstream example can be found here.

This example demonstrates the use of retry back offs

apiVersion: argoproj.io/v1alpha1 kind: Workflow metadata: generateName: retry-backoff- spec: entrypoint: retry-backoff templates: - name: retry-backoff retryStrategy: limit: “10” backoff: duration: “1” # Must be a string. Default unit is seconds. Could also be a Duration, e.g.: “2m”, “6h” factor: “2” maxDuration: “1m” # Must be a string. Default unit is seconds. Could also be a Duration, e.g.: “2m”, “6h” container: image: python:alpine3.6 command: [“python”, -c] # fail with a 66% probability args: [“import random; import sys; exit_code = random.choice([0, 1, 1]); sys.exit(exit_code)”]
