elastic beanstalk 中的克隆环境

Question

我想将我的 Rails EB Linux 从 1.11.8 更新到 2.12.2，所以我克隆了环境并致力于它，但我收到了这个错误：

PG::ConnectionBad (could not connect to server: Connection timed out
    Is the server running on host "example.ccexample.us-east-1.rds.amazonaws.com" (111.11.21.22) and accepting
    TCP/IP connections on port 5432?

另一个错误 -- 可能是同一问题？:

/opt/elastticbeanstalk/hooks/appdeploy/pre/12_db_migration.sh failed.

我的 env 变量都是正确的，所以数据库不应该只是简单地连接吗？

这是错误日志：

我还用新的环境名称更新了 config.yml：

分支默认值：掌握：环境：新名环境默认值：新名字：分支：空存储库：空 RevoltVendor-env：分支：空存储库：空全球的： application_name：应用名称 default_ec2_keyname: 空 default_platform：Puma Ruby 2.5 运行在 64 位亚马逊上 Linux default_region: us-east-1 include_git_submodules：真 instance_profile: 空 platform_name: 空 platform_version: 空简介：eb-cli sc：git workspace_type：申请

如有任何帮助，我们将不胜感激

根据评论。

问题是由 RDS 中的错误的安全组 (SG) 入站规则引起的。 EB克隆操作创建新的SG，没有反映在RDS的SG中。

解决方案是更新 RDS 的 SG 并添加与克隆的 EB 环境关联的 SG。
