Argo Workflows 5

输入和输出

apiVersion: argoproj.io/v1alpha1
kind: Workflow
metadata:
  generateName: input-parameters-
spec:
  entrypoint: main
  arguments:
    parameters:
      - name: message
        value: hello world
  templates:
    - name: main
      inputs:
        parameters:
          - name: message
      container:
        image: docker/whalesay
        command: [cowsay]
        args: ["{{inputs.parameters.message}}"]

可以使用模板标记将一个任务的输出作为另一个任务的输入进行引用：

apiVersion: argoproj.io/v1alpha1
kind: Workflow
metadata:
  generateName: parameters-
spec:
  entrypoint: main
  templates:
    - name: main
      dag:
        tasks:
          - name: generate-parameter
            template: whalesay
          - name: consume-parameter
            template: print-message
            dependencies:
              - generate-parameter
            arguments:
              parameters:
                - name: message
                  value: "{{tasks.generate-parameter.outputs.parameters.hello-param}}"

    - name: whalesay
      container:
        image: docker/whalesay
        command: [sh, -c]
        args: ["echo -n hello world > /tmp/hello_world.txt"]
      outputs:
        parameters:
          - name: hello-param
            valueFrom:
              path: /tmp/hello_world.txt

    - name: print-message
      inputs:
        parameters:
          - name: message
      container:
        image: docker/whalesay
        command: [cowsay]
        args: ["{{inputs.parameters.message}}"]

Artifacts

apiVersion: argoproj.io/v1alpha1
kind: Workflow
metadata:
  generateName: artifacts-
spec:
  entrypoint: main
  templates:
    - name: main
      dag:
        tasks:
          - name: generate-artifact
            template: save-message
          - name: consume-artifact
            template: print-message
            dependencies:
              - generate-artifact
            arguments:
              artifacts:
                - name: message
                  from: "{{tasks.generate-artifact.outputs.artifacts.hello-art}}"

    - name: save-message
      container:
        image: docker/whalesay
        command: [sh, -c]
        args: ["cowsay hello world > /tmp/hello_world.txt"]
      outputs:
        artifacts:
          - name: hello-art
            path: /tmp/hello_world.txt

    - name: print-message
      inputs:
        artifacts:
          - name: message
            path: /tmp/message
      container:
        image: docker/whalesay
        command: [sh, -c]
        args: ["cat /tmp/message"]
