我試圖在Google的容器引擎（GKE）上部署我的Spring Boot/JHipster應用程序。我已經想出了大部分內容，但是我的數據庫實例（通過Google SQL代理運行在Google Cloud SQL上的PostgreSQL實例）遇到問題。雲SQL代理和權限不足
- 我在雲中設置了我的PostreSQL實例，並創建了我的應用程序的數據庫和用戶。
- 我已經創建了一個具有Cloud SQL Client角色的SQL服務 - 我抓住了JSON密鑰，並用它來創建我的cloudsql-instance-credentials。我也創建了我的cloudsql-db-credentials。
- 我已將額外的位添加到我的部署yaml文件。我基本上從this GitHub sample克隆了yaml文件，並用我自己的Docker鏡像（託管在Google Container Registry中）替換了所有對wordpress的引用。我還更新了代理塊，像這樣：
deployment.yaml片段：
- image: gcr.io/cloudsql-docker/gce-proxy:1.09
name: cloudsql-proxy
command: ["/cloud_sql_proxy", "--dir=/cloudsql",
"-instances=[my-project]:us-central1:[my-sql-instance-id]=tcp:5432",
"-credential_file=/secrets/cloudsql/credentials.json"]
最後，我已經更新了我的春節，引導配置YAML文件中，就像這樣：
datasource:
type: com.zaxxer.hikari.HikariDataSource
url: jdbc:postgresql://google/[my-database]?socketFactory=com.google.cloud.sql.postgres.SocketFactory&socketFactoryArg=[my-project]:us-central1:[my-sql-instance-id]
username: ${DB_USER}
password: ${DB_PASSWORD}
當我部署了kubectl create時，圖像部署了，但未能啓動應用程序。下面是從我的日誌突出位：

這種「權限不足」的錯誤彈出了很多在計算器上，但我還沒有發現一個問題，那是相當的相同的情況我的。這看起來像一個通用的OAuth級錯誤。我覺得我已經根據說明再次檢查了我的設置，並且我不確定在哪裏可以找到任何其他線索。
任何想法？
更新：
由於瓦迪姆的指針，我已經成功地讓過去的「權限不足」的問題。可悲的是，當我的應用程序試圖建立與數據庫的連接時（特別是當Liquibase試圖開始連接到數據庫以運行遷移腳本時），我的應用程序在啓動時仍然失敗。
我的新的錯誤是在駕駛員座級：

仔細檢查您是否在設置GKE時啓用了Cloud SQL範圍：https://medium.com/google-cloud/updating-google-container-engine-vm-scopes-with-zero-downtime-50bff87e5f80 – Vadim
這絕對改變了事情。我仍然遇到JDBC問題，但它不再是權限不足的問題。我的新錯誤是一個'java.net.SocketException：已連接'錯誤，我猜是某種池化問題。我對如何繼續前進有一些想法。謝謝！ – bcholmes
