Question

我已经制作了一个Dockerfile，用于将我的node.js应用程序部署到谷歌容器引擎中。它看起来如下所示

FROM node:0.12
COPY google-cloud-sdk /google-cloud-sdk
RUN /google-cloud-sdk/bin/gcloud init
COPY bpe /bpe
CMD cd /bpe;npm start

我应该在Dockerfile中使用gcloud init，因为我的node.js应用程序正在使用gcloud-node模块在GCS中创建存储桶。当我使用上面的dockerfile并建立docker时，它失败并出现以下错误

sudo docker build -t gcr.io/[PROJECT_ID]/test-node:v1 .

我通过在google-cloud-sdk源代码中对验证密钥进行硬编码来完成它。请让我知道解决此问题的正确方法。

Answer 1

gcloud init是一个运行

的包装器命令

gcloud config configurations create MY_CONFIG
gcloud config configurations activate MY_CONFIG
gcloud auth login
gcloud config set project MY_PROJECT

允许用户选择配置，登录（通过浏览器）并选择项目。

对于您的用例，您可能不想使用gcloud init，而是应该从https://console.cloud.google.com/iam-admin/serviceaccounts/project?project=MY_PROJECT下载服务帐户密钥文件，使其在docker容器中可访问并通过

激活它

gcloud auth activate-service-account --key-file my_service_account.json
gcloud config set project MY_PROJECT

从容器引擎中使用gcs的更好方法是授予群集权限。例如，如果您使用devstorage.read_only作用域创建了VM，则即使您的服务帐户具有写入存储桶的权限，尝试写入存储桶也会失败。你需要devstorage.full_control或devstorage.read_write。

创建集群时，我们可以使用以下命令

gcloud container clusters create catch-world \
        --num-nodes 1 \
        --machine-type n1-standard-1 \
        --scopes https://www.googleapis.com/auth/devstorage.full_control

无法在dockerfile
