serverless - 无服务器 - 计划事件未创建 CloudWatch 事件

Question

Serverless 不会创建 CloudWatch Events 作为 lambda 的触发器。没有警告或错误。

functions:
  aggregate:
    handler: statistics.handler
    events:
      - schedule:
          rate: rate(10 minutes)

Answer 1

Serverless 的示例并未展示缩进的关键性质。https://serverless.com/framework/docs/providers/aws/events/schedule/#schedule

functions:
  aggregate:
    handler: statistics.handler
    events:
    # "- schedule:" has to start at the same indentation as the "events:" above it.
    - schedule:
        # The CloudWatch Events Rules have to be exactly 4 spaces indented below the "- schedule:"
        rate: rate(10 minutes)
        # ... other fields

关键：

• - schedule:与events:上面对齐。
• 对齐下一行​​，例如rate: rate(6 minutes)从- schedule:

示例代码：

service: my-service
provider:
  name: aws
  region: us-west-2
  runtime: nodejs10.x
functions:
  hello:
    handler: handler.hello
    events:
    - schedule:
        rate: cron(*/5 * * * ? *)
        enabled: true

和

module.exports.hello = (event, context, callback) => {
  console.log("Hello, world!");
  callback(null);
};

简单地缩进 - 像我期望的那样安排 2 个空格不会在 AWS 中创建 cloudwatch 事件。2 个空格的单次更改决定了是否创建了 cloudwatch 事件规则。

注意：两个缩进之间不会引发错误，但它会创建 6 个与 8 个 AWS 资源（缺少 2 个不创建 cloudwatch 事件规则）。
