如何使用来自 Jenkins 管道的 fabric8 maven 插件将 docker 图像推送到 Google Container Registry：未经授权

Question

我一直在努力使用 Jenkins 管道上的 fabric8 maven 插件将 docker 图像推送到 Google Container Registry。我检查了 Whosebug 上的每个问题，但 none 解决了我的问题。

这是我的设置：

Kubernetes 集群运行在 Google Kubernetes 引擎上。我已经部署了一个带有 Jenkins 服务器的 pod，该服务器使用 Kubernetes CI 插件启动代理，基于这个自定义图像：

FROM openjdk:8

RUN apt-get update && \
    apt-get -y install \
    apt-transport-https \
    ca-certificates \
    curl \
    software-properties-common
RUN curl -fsSL https://download.docker.com/linux/ubuntu/gpg | apt-key add -
RUN add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu xenial stable" && \
    apt-get update &&  \
    apt-get -y install docker-ce

RUN curl https://dl.google.com/dl/cloudsdk/release/google-cloud-sdk.tar.gz > /tmp/google-cloud-sdk.tar.gz

RUN mkdir -p /usr/local/gcloud \
  && tar -C /usr/local/gcloud -xvf /tmp/google-cloud-sdk.tar.gz \
  && /usr/local/gcloud/google-cloud-sdk/install.sh

ENV PATH $PATH:/usr/local/gcloud/google-cloud-sdk/bin

此代理有 Java 8 和 Docker。

我想使用 fabric8 maven 插件来执行 docker 镜像构建并推送到 Google Container Registry。关键是无论我做什么，我总是会遇到这个错误（未经授权）：

Unable to push 'eu.gcr.io/myprojectid/gke-springboot-sample' from registry 'eu.gcr.io' : unauthorized: You don't have the needed permissions to perform this operation, and you may have invalid credentials. To authenticate your request, follow the steps in: https://cloud.google.com/container-registry/docs/advanced-authentication -> [Help 1]

注意：

我已经创建了一个与我的 GC 项目相关联的服务帐户并授予它以下权限：项目编辑器和存储管理员。
我已经配置了与属于该服务帐户的 key.json 文件相关联的全局 Jenkins 机密（云注册表凭证）

到目前为止，我已经在我的管道中尝试了所有的东西：

1: oauth2accesstoken

stage("Build docker image") {
    agent {
        label 'jenkins-slave'
    }
    steps {
        container('jenkins-slave'){
            script {
                sh "./mvnw clean build fabric8:build"
                withCredentials([file(credentialsId: 'cloud-registry-credentials', variable: 'crc')]) {
                    sh "gcloud auth print-access-token | docker login -u oauth2accesstoken --password-stdin https://eu.gcr.io"
                    sh "./mvnw fabric8:push"
                }
            }
        }
    }
}

输出：

Answer 1

您可能正在寻找 Jenkins Google Container Registry Auth Plugin。

另一个可能的原因可能是，用户 jenkins-cr 没有分配所需的角色 storage.admin，在 Cloud IAM 中...这是相关的 documentation。刚刚看到你已经分配了它；也许仔细检查一下。

如果这与 fabric8 插件相关，您也可以获得支持 there。

此外，因此它是一个桶，那个桶的 ACL 最终可能会干扰。

Answer 2

在 maven ./mvnw fabric8:push 命令中添加 -X 标志后，我发现了以下 DEBUG 行：AuthConfig: no credentials found.

我不得不深入研究 AuthConfigFactory class 的源代码，发现问题是它没有找到之前生成的 /home/jenkins/.docker/config.json 文件。

问题是这个容器的主目录是 /root，所以它在 /root/.docker/config.json 中寻找它，但它不在那里。作为解决方法，我添加了 sh "cp /home/jenkins/.docker/config.json /root/.docker/config.json"，现在它就像一个魅力：

[DEBUG] F8> AuthConfig: credentials from ~.docker/config.json
[INFO] F8> myprojectid/gke-springboot-sample:0.0.1-SNAPSHOTsnapshot-180813-080943-0179 in 5 seconds
