Bitbucket无法加载google云密钥文件

Question

Bitbucket无法读取我的带有Google cloud service key的base64编码的json文件。我已经成功地对Bitbucket尝试解码的同一文件进行了编码和解码。但是由于base64: invalid input错误，Bitbucket无法做到这一点。以下是完整的错误消息：

Status: Downloaded newer image for bitbucketpipelines/google-app-engine-deploy:0.6.1
INFO: Setting up environment.
echo "${KEY_FILE}" | base64 -d >> /tmp/key-file.json
base64: invalid input
gcloud auth activate-service-account --key-file /tmp/key-file.json --quiet --verbosity=warning
ERROR: (gcloud.auth.activate-service-account) Could not read json file /tmp/key-file.json: Unterminated string starting at: line 3 column 17 (char 49)

gcloud app --quiet deploy app.yaml --version=14 --promote --stop-previous-version --verbosity=debug --quiet --verbosity=warning
ERROR: (gcloud.app.deploy) You do not currently have an active account selected.

据我所知，它在"project_id": "上失败了。解码后的文件如下所示：

{
  "type": "service_account",
  "project_id": "project-318",
  "private_key_id": "...",
  ...
}

我尝试先通过环境变量，然后通过文件提供我的base64编码的密钥文件。但也有同样的错误。当无法提取JSON时，bitbucket会写入以下错误：ERROR: (gcloud.auth.activate-service-account) Could not read json file /tmp/key-file.json: No JSON object could be decoded

原来来自google cloud的密钥文件包含换行符：\n。所以结果base64编码的文件看起来也是这样的：

.....

但为了将其传递给Bitbucket，您需要在一行中完成所有操作：

在我手动删除新的线条符号后，它给出了成功消息：Activated service account credentials for: [project]

我可以建议使用GCP的KMS (密钥管理服务)。解密base64非常容易，在KMS下，您需要具有相应的用户角色才能解密它。使用KMS的步骤是以下代码片段：

KEYRING=kubernetes-secrets
KEY=generic-type-encryption-key

gcloud kms keyrings create $KEYRING --location asia-east2
gcloud kms keys create $KEY --location asia-east2 \
                            --keyring $KEYRING \
                            --purpose encryption

gcloud kms encrypt --location asia-east2 \
                       --keyring $KEYRING \
                       --key $KEY \
                       --plaintext-file example.txt \
                       --ciphertext-file encrypted.example.txt
