Tekton使用Kaniko构建Docker镜像-请使用--Dockerfile在构建上下文中提供一个Dockerfil

Question

我是Tekton的新手(https://tekton.dev/)我正在尝试

1. 克隆存储库
2. 使用Dockerfile构建docker映像

我有一个Tekton管道，当我尝试执行它时，我会得到以下错误：

错误：解析dockerfile路径时出错：请使用--dockerfile 在构建上下文中提供一个dockerfile的有效路径

请在下面找到Tekton清单：

1.管道.yml

apiVersion: tekton.dev/v1beta1
kind: Pipeline
metadata:
name: clone-read
spec:
description: | 
This pipeline clones a git repo, then echoes the README file to the stout.
params:
- name: repo-url
type: string
description: The git repo URL to clone from.
- name: image-name
type: string
description: for Kaniko
- name: image-path
type: string
description: path of Dockerfile for Kaniko
workspaces:
- name: shared-data
description: | 
This workspace contains the cloned repo files, so they can be read by the
next task.
tasks:
- name: fetch-source
taskRef:
name: git-clone
workspaces:
- name: output
workspace: shared-data
params:
- name: url
value: $(params.repo-url)
- name: show-readme
runAfter: ["fetch-source"]
taskRef:
name: show-readme
workspaces:
- name: source
workspace: shared-data
- name: build-push
runAfter: ["show-readme"]
taskRef:
name: kaniko
workspaces:
- name: source
workspace: shared-data
params:
- name: IMAGE
value: $(params.image-name)  
- name: CONTEXT
value: $(params.image-path)    

1.PipelineRun.yml

apiVersion: tekton.dev/v1beta1
kind: PipelineRun
metadata:
name: clone-read-run
spec:
pipelineRef:
name: clone-read
podTemplate:
securityContext:
fsGroup: 65532
workspaces:
- name: shared-data
volumeClaimTemplate:
spec:
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 1Gi
# - name: git-credentials
#   secret:
#     secretName: git-credentials
params:
- name: repo-url
value: https://github.com/iamdempa/tekton-demos.git
- name: image-name
value: "python-test"
- name: image-path
value: $(workspaces.shared-data.path)/BuildDockerImage2  

这是我的存储库结构：

. . .
.
├── BuildDockerImage2
│   ├── 1.show-readme.yml
│   ├── 2. Pipeline.yml
│   ├── 3. PipelineRun.yml
│   └── Dockerfile
├── README.md
. . .
7 directories, 25 files

有人能帮我这里怎么了吗？

谢谢

Answer 1

我找到了这个问题。问题在于我提供路径的方式。

在kaniko任务中，CONTEXT变量确定Dockerfile的路径。默认值设置为./，并带有一些附加前缀，如下所示：

$(workspaces.source.path)/$(params.CONTEXT)

这意味着，workspaces的路径已经被附加，我不需要像下面的image-path值中提到的那样附加该部分：

$(workspaces.shared-data.path)/BuildDockerImage2  

相反，我不得不将文件夹名称如下：

- name: image-path
value: BuildDockerImage2 

这解决了我的问题。
