通过配置使用工作流集群Artifacts，可以在工作流各个步骤之间传递参数，一个步骤的输出可以作为另一个步骤的输入，从而完成复杂工作流步骤的编排。本文介绍如何使用阿里云OSS作为Artifacts的存储，在工作流步骤间传递参数。
前提条件
已开通阿里云对象存储（OSS）服务。具体操作，请参见开通OSS服务。
操作步骤
配置阿里云OSS。具体操作，请参见Configuring Alibaba Cloud OSS。
使用以下YAML内容，创建
artifact-passing.yaml文件。apiVersion: argoproj.io/v1alpha1 kind: Workflow metadata: generateName: artifact-passing- spec: entrypoint: artifact-example templates: - name: artifact-example steps: - - name: generate-artifact template: whalesay - - name: consume-artifact template: print-message arguments: artifacts: # bind message to the hello-art artifact. # generated by the generate-artifact step. - name: message from: "{{steps.generate-artifact.outputs.artifacts.hello-art}}" - name: whalesay container: image: docker/whalesay:latest command: [sh, -c] args: ["cowsay hello world | tee /tmp/hello_world.txt"] outputs: artifacts: # generate hello-art artifact from /tmp/hello_world.txt. # artifacts can be directories as well as files. - name: hello-art path: /tmp/hello_world.txt - name: print-message inputs: artifacts: # unpack the message input artifact. # and put it at /tmp/message. - name: message path: /tmp/message container: image: alpine:latest command: [sh, -c] args: ["cat /tmp/message"]执行以下命令，提交工作流。
argo submit artifact-passing.yaml执行以下命令，查看工作流状态。
argo list
