Answer 1

从你的错误消息,我们可以猜测TaskRun (PipelineRun)尝试运行这个任务没有定义工作空间使用与你的任务。

假设我想调用你的Task:我会写一个Pipeline，它应该包括如下内容:

apiVersion: tekton.dev/v1beta1
kind: Pipeline
metadata:
name: hello-world
spec:
tasks:
- name: hello-world-task
taskRef:
name: hello-world
workspaces:
- name: output
workspace: my-workspace
workspaces:
- name: my-workspace
optional: true

然后，用下面的PipelineRun命令启动这个管道:

apiVersion: tekton.dev/v1beta1
kind: PipelineRun
metadata:
name: hello-world-0
spec:
pipelineRef: hello-world
workspaces:
- name: my-workspace
volumeClaimTemplate:
spec:
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 1Gi
