Simple Batch Workflow

Simple Batch Workflow

Create the manifest workflow-whalesay.yaml and let’s deploy the whalesay example from before using Argo.

cat <<EoF > ~/environment/batch_policy/workflow-whalesay.yaml
apiVersion: argoproj.io/v1alpha1
kind: Workflow
metadata:
  generateName: whalesay-
spec:
  entrypoint: whalesay
  templates:
  - name: whalesay
    container:
      image: docker/whalesay
      command: [cowsay]
      args: ["This is an Argo Workflow!"]
EoF

Now deploy the workflow using the argo CLI.

You can also run workflow specs directly using kubectl but the argo CLI provides syntax checking, nicer output, and requires less typing. For the equivalent kubectl commands, see Argo CLI.

argo -n argo submit --watch ~/environment/batch_policy/workflow-whalesay.yaml
