Tekton挂载路径工作区问题.路径错误

Question

目前，我正在尝试部署图腾-你好-世界。我已经为同样的脚本编写了一个脚本，但是它并不像它应该的那样工作。我确信这个问题与工作空间有关。

更新这里是我的task-tutum-deploy.yaml代码-

apiVersion: tekton.dev/v1beta1
kind: Task
metadata:
  name: tutum-deploy
spec:
  steps:
    - name: tutum-deploy
      image: bitnami/kubectl
      script: |
        kubectl apply -f /root/tekton-scripts/tutum-deploy.yaml
  workspaces:
    - name: messages
      optional: true
      mountPath: /root/tekton-scripts/

错误-

root@master1:~/tekton-scripts# tkn taskrun logs tutum-deploy-run-8sq8s -f -n default
[tutum-deploy] + kubectl apply -f /root/tekton-scripts/tutum-deploy.yaml
[tutum-deploy] error: the path "/root/tekton-scripts/tutum-deploy.yaml" cannot be accessed: stat /root/tekton-scripts/tutum-deploy.yaml: permission denied

container step-tutum-deploy has failed  : [{"key":"StartedAt","value":"2021-06-14T12:54:01.096Z","type":"InternalTektonResult"}]

PS -我已经将我的脚本放在- /root/tekton-scripts/tutum-deploy.yaml的主节点上。

root@master1:~/tekton-scripts# ls -l tutum-deploy.yaml 
-rwxrwxrwx 1 root root 626 Jun 11 11:31 tutum-deploy.yaml

旧脚本

这是我的task-tutum-deploy.yaml代码-

apiVersion: tekton.dev/v1beta1
kind: Task
metadata:
  name: tutum-deploy
spec:
  workspaces:
    - name: messages
      optional: true
      mountPath: /root/tekton-scripts/tutum-deploy.yaml
  steps:
    - name: tutum-deploy
      image: bitnami/kubectl
      command: ["kubectl"]
      args:
        - "apply"
        - "-f"
        - "./tutum-deploy.yaml"

下面是我的tutum-deploy.yaml代码，它存在于具有读写和执行权限的Kubernetes集群的机器(主节点)上-

apiVersion: apps/v1
kind: Deployment
metadata:
  name: hello-world-tutum
  labels:
    service: hello-world-tutum
spec:
  replicas: 1
  selector:
    matchLabels:
      service: hello-world-tutum
  template:
    metadata:
      labels:
        service: hello-world-tutum
    spec:
      containers:
      - name: tutum-hello-world
        image: tutum/hello-world:latest
        ports:
        - containerPort: 80

---
apiVersion: v1
kind: Service
metadata:
  name: hello-world-tutum
spec:
  type: NodePort
  selector:
    service: hello-world-tutum
  ports:
  - name: "80"
    port: 80
    targetPort: 80
    nodePort: 30050

我从Kubernetes集群的主节点运行了以下命令-

1. kubectl apply -f task-tutum-deploy.yaml

2. tkn task start tutum-deploy

错误-

使用tekton命令- $ tkn taskrun logs tutum-deploy-run-tvlll -f -n default

task tutum-deploy has failed: "step-tutum-deploy" exited with code 1 (image: "docker-pullable://bitnami/kubectl@sha256:b83299ee1d8657ab30fb7b7925b42a12c613e37609d2b4493b4b27b057c21d0f"); for logs run: kubectl -n default logs tutum-deploy-run-tvlll-pod-vbl5g -c step-tutum-deploy

[tutum-deploy] error: the path "./tutum-deploy.yaml" does not exist

container step-tutum-deploy has failed  : [{"key":"StartedAt","value":"2021-06-11T14:01:49.786Z","type":"InternalTektonResult"}]

错误来自YAML的这一部分：

spec:
  workspaces:
    - name: messages
      optional: true
      mountPath: /root/tekton-scripts/tutum-deploy.yaml

spec.workspaces.mountPath需要一个目录，而不是您在这里指定的文件。您的意思可能是/root/tekton-scripts/，但我不熟悉tutum-hello-world。

如果您查看文献资料，您将看到所有对mountPath的引用都是目录而不是文件。
