我在tf中对这些资源进行了以下更改
- aws_db_proxy_target
- aws_db_proxy_default_target_group
- aws_db_proxy
当我将aws提供程序切换到3.20.0时，故障不再发生。然而，回购剩余部分的版本需要2.x.
我尝试使用多个提供商：
provider "aws" {
version = "~> 2.60.0"
region = "us-west-2"
}
provider "aws" {
version = "~> 3.20.0"
region = "us-west-2"
alias = "version_3"
}
module "my-module"
...
...
providers = {
aws = aws.version_3
}
}
但是运行terraform init返回：
No provider "aws" plugins meet the constraint " < 4.0, < 4.0,>= 2.0,>= 2.0,>= 2.25,>= 2.42,>= 2.42,>= 2.49,>= 2.49,>= 2.49,>= 2.49,>= 2.49,~> 2.0,~> 2.0,~> 2.0,~> 2.0,~> 2.0,~> 2.0,~> 2.0,~> 2.0,~> 2.0,~> 2.60.0,~> 3.20.0".
The version constraint is derived from the "version" argument within the
provider "aws" block in configuration. Child modules may also apply
provider version constraints. To view the provider versions requested by each
module in the current configuration, run "terraform providers".
To proceed, the version constraints for this provider must be relaxed by
either adjusting or removing the "version" argument in the provider blocks
throughout the configuration.

Error: no suitable version is available
我以前在多个提供程序中遇到过这个问题。最后，我在模块内部嵌入了第二个带有别名的提供程序块，它就工作了。显然，我建议您将该模块中的任何敏感值或更改值作为变量传递。
这不是最优雅的方式，但它为我完成了任务。希望你也能做到。
祝你好运！
