解析 dockerfile 路径时出错:请使用 --dockerfile 在构建上下文中提供指向 Dockerfile

Question

apiVersion: v1
kind: Pod
metadata:
  name: kaniko
spec:
  containers:
  - name: kaniko
    image: gcr.io/kaniko-project/executor:latest
    args:
          - "--context=dir:///workspace"
          - "--dockerfile=/workspace/Dockerfile"
          - "--destination=gcr.io/kubernetsjenkins/jenkinsondoc:latest"
    volumeMounts:
      - name: kaniko-secret
        mountPath: /secret
      - name: context
        mountPath: /workspace
    env:
      - name: GOOGLE_APPLICATION_CREDENTIALS
        value: /secret/kaniko-secret.json
  restartPolicy: Never
  volumes:
    - name: kaniko-secret
      secret:
        secretName: kaniko-secret
    - name: context
      hostPath:
        path: /home/sabadsulla/kanikodir

我正在 kubernetes pod 上运行 kaniko 来构建一个 docker 镜像并推送到 GCR。

当我使用谷歌云存储进行CONTEXT_PATH它工作正常时，但是我需要使用 Local_directory(意味着使用 pod 的共享卷(作为CONTEXT_PATH它抛出一个错误

"Error: error resolving dockerfile path: please provide a valid path to a Dockerfile within the build context with --dockerfile

用法：

I tried with args "--context=/workspace" , "--context=dir://workspace" , it gives the same error

Answer 1

文件夹看起来像

在主机中：

/home/sabadsulla/kanikodir/Dockerfile

当它变成PV/PVC时，在豆荚容器中

/workspace/Dockerfile

那么对于kanino executor，如果我们把上下文映射到workspace，dockerfile 就会涉及到上下文Dockerfile，所以

--context=/workspace
--dockerfile=Dockerfile

Answer 2

嗨，我刚刚解决了这个问题。

我的节点名称：m1.env.lab.io

my Dockerfile path: /root/kaniko/demo1/Dockerfile
FROM ubuntu
ENTRYPOINT ["/bin/bash", "-c", "echo hello"]

pod.yaml in/root/kaniko/demo1/pod.yaml：

apiVersion: v1
kind: Pod
metadata:
  name: kaniko
  namespace: kaniko
spec:
  nodeName: m1.env.lab.io
  containers:
  - name: kaniko
    image: gcr.io/kaniko-project/executor:latest
    args: ["--verbosity=trace",
           "--log-format=color",
           "--dockerfile=Dockerfile",
           "--context=dir:///workspace/",
           "--destination=registry.local/cloud2go/kaniko-ubuntu:v0.1"] # no account and password for my registry.
    volumeMounts:
      - name: dockerfile-storage
        mountPath: /workspace/
  restartPolicy: Never
  volumes:
    - name: dockerfile-storage
      hostPath:
         path: /root/kaniko/demo1

使用 kaniko 容器和卷挂载作为持久卷声明。
请尝试使用"--dockerfile=./Dockerfile">

      containers:
      - name: kaniko
        image: gcr.io/kaniko-project/executor:latest
        args: ["--dockerfile=./Dockerfile",
               "--context=/workspace/",
               "--destination=gcr.io/kubernetsjenkins/jenkinsondoc:latest"]
        volumeMounts:
          - name: kaniko-secret
            mountPath: /secret
          - name: context
            mountPath: /workspace/

使用默认值：
--dockerfile string -要构建的 dockerfile 的路径。(默认为"Dockerfile"(
--context 字符串 -dockerfile 构建上下文的路径。(默认"/工作区/"(

甚至这句话也有效：

args: ["--destination=gcr.io/kubernetsjenkins/jenkinsondoc:latest"]希望这有帮助。您能否对其进行测试并与结果分享？
