我在 kubernetes pod 上运行 kaniko 以构建 docker 映像并推送到 GCR。

当我为 CONTEXT_PATH 使用谷歌云存储时,它工作正常,但我需要使用 Local_directory(意味着使用 pod 的共享卷)作为 CONTEXT_PATH 它会引发错误

"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

该文件夹看起来像

在主机:

/home/sabadsulla/kanikodir/Dockerfile

当它变成 PV/PVC 时,在 pod 容器中

/workspace/Dockerfile

那么对于kanino executor,如果我们将上下文映射到workspace,dockerfile将与上下文相关Dockerfile,所以

--context=/workspace
--dockerfile=Dockerfile

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"]

/root/kaniko/demo1/pod.yaml 中的 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 容器和安装的卷作为持久卷声明。
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“Dockerfile”)
--context string - dockerfile 构建上下文的路径。(默认“/workspace/”)

甚至这句话也有效:
args: ["--destination=gcr.io/kubernetsjenkins/jenkinsondoc:latest"]
希望这有帮助。你能测试一下并分享结果吗?
