【问题描述】：

我正在尝试针对 kubernetes 上的 postgres 数据库运行 flyway docker image 7.3.2：

当我运行作业时，我的输出是：

Flyway Community Edition 7.3.2 by Redgate
ERROR:
Unable to obtain connection from database (jdbc:postgresql://xxx.eu-west-2.rds.amazonaws.com:5432/xxx flyway.user=postgres flyway.password=****************) for user 'null': The server requested password-based authentication, but no password was provided.
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
SQL State  : 08004
Error Code : 0
Message    : The server requested password-based authentication, but no password was provided.

Caused by: org.postgresql.util.PSQLException: The server requested password-based authentication, but no password was provided.

它输出的设置是正确的，应该可以启用连接。

我通过一个配置映射传入我的flyway.conf：

apiVersion: v1
kind: ConfigMap
metadata:
  name: flyway-configmap
data:
  flyway.conf:
    flyway.url=jdbc:postgresql://xxx.eu-west-2.rds.amazonaws.com:5432/xxx
    flyway.user=postgres
    flyway.password=xxx

谁能帮我解决我做错了什么？

【问题讨论】：

标签： postgresql kubernetes flyway configmap

【解决方案1】：

如果这确实是您的ConfigMap，那么它缺少: 之后的| 字符，这将使该yaml 密钥成为a newline delimited scalar。该理论也与您的错误消息相吻合，表明 整个事物 被视为 flyway.url

的值

你想要什么：

  flyway.conf: |
    flyway.url=jdbc:postgresql://xxx.eu-west-2.rds.amazonaws.com:5432/xxx
    flyway.user=postgres
    flyway.password=xxx
