python - 从 Docker 中的 Python 访问 GCP secret 管理器中的 secret - nontsop 权限被拒绝

Question

我正在构建一个简单的应用程序，它将 Twilio 凭据存储在 GCP Secret Manager 中，并在需要时将它们拉下来。但是，我不断收到有关项目资源的拒绝权限错误 (403):

google.api_core.exceptions.PermissionDenied:403 资源项目权限被拒绝。

我正在使用设置为包含服务帐户凭据的 JSON 文件路径的环境变量。

这是我已经尝试过的:

确保在 GCP Console 中正确设置权限。服务帐户被设置为项目的所有者和项目级别的 secret 访问者，以及每个 secret 的对象级别的 secret 访问者。

确保环境变量设置正确 - 我已验证 ENV 变量设置正确并且可以读取它指向的文件。我可以通过将 ENV 变量作为 JSON 文件打开来打印文件的内容。

通过将我的 JSON 文件的内容与 GCP 控制台中的数据进行比较，确认身份验证信息是正确的

我使用 gcloud CLI 在服务帐户下登录，然后使用 CLI 命令检索完全相同的 secret

我可以成功访问并将数据推送到 GCS 存储桶，这表明凭据已从 ENV 变量

正确加载

我曾尝试以多种方式访问​​这些 secret 。我试过其他方法，比如列出项目中的 secret 。都返回权限错误。

作为引用，我一直在遵循 https://cloud.google.com/secret-manager/docs/reference/libraries#client-libraries-install-python 中的说明。并且还一直在使用官方客户端库文档来探索还有什么可能是错误的。没有什么能真正帮助我在这里。

我已经阅读了我能找到的所有资源，但没有任何帮助。有什么想法吗？

谢谢!!!

编辑:在下面添加代码:

def access_secret(project_id, secret_id, version):
    """
    Access a secret- API token, etc- stored in Secret Manager

    Code from https://cloud.google.com/secret-manager/docs/creating-and-accessing-secrets#secretmanager-access-secret-version-python
    """
    client = secretmanager.SecretManagerServiceClient()

    # Build the resource name of the secret version
    name = client.secret_version_path(project_id, secret_id, version)

    # Access the secret version
    response = client.access_secret_version(name)

    # Return the secret payload
    payload = response.payload.data.decode('UTF-8')

    return payload

EDIT2:这是我在其中运行此代码的 Dockerfile:

FROM python:3.8.2-slim-buster

WORKDIR /build

# Copy in the requirements.txt file and service account credentials
COPY requirements.txt <CREDENTIALS_FILENAME>.json /build/ 

ENV PYTHONUNBUFFERED=1 \
    GOOGLE_APPLICATION_CREDENTIALS=/build/<CREDENTIALS_FILENAME>.json \
    VOICEMAIL_TIMEOUT=55 \
    MULTIRING_TIMEOUT=15 \
    GCS_VM_BUCKET=<MY GCS BUCKET NAME> \
    GCP_PROJECT=<MY GCP PROJECT NAME> \
    PHONE_NUMBER=<PHONE NUMBER> \
    TWILIO_ACCOUNT_SID_VERSION=1 \
    TWILIO_AUTH_TOKEN_VERSION=1

# Install packages
RUN pip install -r requirements.txt

# Navigate to the directory containing the Python code
WORKDIR /code/src/

EXPOSE 5000

# Run the actual Python code
CMD ["python", "main.py"]

后来，我有了调用上面函数的 Python 代码:

GCS_VM_BUCKET = os.environ['GCS_VM_BUCKET']
GCP_PROJECT = os.environ['GCP_PROJECT']

TWILIO_SID = access_secret(GCP_PROJECT, 'TWILIO_ACCOUNT_SID', os.environ['TWILIO_ACCOUNT_SID_VERSION'])
TWILIO_AUTH_TOKEN = access_secret(GCS_PROJECT, 'TWILIO_AUTH_TOKEN', os.environ['TWILIO_AUTH_TOKEN_VERSION'])

其中 TWILIO_ACCOUNT_SID 和 TWILIO_AUTH_TOKEN 是 GCP 中的 secret 名称。

Answer 1

好的，原来我使用的是项目名称而不是项目 ID。

叹。至少答案很简单。 :]
