官方文档的例子中，有一个 steps
https://argoproj.github.io/argo-workflows/examples/#hello-world
以下脚本中主要创建了
3个steps + 1个template
apiVersion: argoproj.io/v1alpha1
kind: Workflow
metadata:
generateName: steps-
spec:
entrypoint: hello-hello-hello
# This spec contains two templates: hello-hello-hello and whalesay
templates:
- name: hello-hello-hello
# Instead of just running a container
# This template has a sequence of steps
steps:
- - name: hello1 # hello1 is run before the following steps
template: whalesay
arguments:
parameters:
- name: message
value: "hello1"
- - name: hello2a # double dash => run after previous step
template: whalesay
arguments:
parameters:
- name: message
value: "hello2a"
- name: hello2b # single dash => run in parallel with previous step
template: whalesay
arguments:
parameters:
- name: message
value: "hello2b"
# This is the same template as from the previous example
- name: whalesay
inputs:
parameters:
- name: message
container:
image: docker/whalesay
command: [cowsay]
args: ["{{inputs.parameters.message}}"]
这里的结构实际上是一个 二维数组 [[hello1],[hello2a,hello2b]]
steps:
- - name: hello1
- - name: hello2a
- name: hello2b
这里还有一个 DAG 模型的 执行器
apiVersion: argoproj.io/v1alpha1
kind: Workflow
metadata:
generateName: dag-diamond-
spec:
entrypoint: diamond
templates:
- name: echo
inputs:
parameters:
- name: message
container:
image: alpine:3.7
command: [echo, "{{inputs.parameters.message}}"]
- name: diamond
dag:
tasks:
- name: A
template: echo
arguments:
parameters: [{name: message, value: A}]
- name: B
dependencies: [A]
template: echo
arguments:
parameters: [{name: message, value: B}]
- name: C
dependencies: [A]
template: echo
arguments:
parameters: [{name: message, value: C}]
- name: D
dependencies: [B, C]
template: echo
arguments:
parameters: [{name: message, value: D}]
