AWS Typescript CDK：存在此 Lambda 函数的版本 (1)。修改函数创建新版本

Question

这是我的 CDK 代码：

    const addVersion = (resourcePrefix: string, lambda: NodejsFunction) => {
      const version = new Version(this, `${resourcePrefix}Version`, {
        lambda,
      });

      const alias = new Alias(this, `${resourcePrefix}VersionAlias`, {
        aliasName: 'current',
        version,
      });

      alias.node.addDependency(version);
    }

第一次部署成功，后续部署失败。我假设这是因为 CDK 每次都试图创建一个新版本的 Lambda 函数，即使源代码没有被修改。我怎样才能让它停止这样做？

Answer 1

参考 Lambda 的 currentVersion 属性:

new Alias(this, `${resourcePrefix}VersionAlias`, {
  aliasName: 'current',
  version: lmbda.currentVersion,
});

docs: The fn.currentVersion property can be used to obtain a lambda.Version resource that represents the AWS Lambda function defined in your application. Any change to your function's code or configuration will result in the creation of a new version resource. You can specify options for this version through the currentVersionOptions property.
