Can I change AWS CloudFormation hooks timeout

Yes, you can change the timeout for AWS CloudFormation hooks by specifying the Timeout property in your CloudFormation stack template.

The Timeout property specifies the amount of time, in minutes, that AWS CloudFormation should wait for the hook to complete before timing out. By default, the timeout for hooks is set to 30 minutes.

To change the timeout, you can add the Timeout property to your CloudFormation resource that uses the hook. For example, if you have a resource named MyCustomResource that uses a hook, you can add the Timeout property to the resource definition as follows:

MyCustomResource:
  Type: Custom::MyCustomResource
  Properties:
    ...
    Timeout: 60

In the example above, the Timeout property is set to 60 minutes (1 hour). You can adjust the value as needed for your specific use case.

Note that increasing the timeout for hooks may increase the total time it takes for your stack operation to complete, so it's important to balance the timeout value with the overall operation duration.

The defaul timeout is 30 seconds for all hooks, but you can configure a callback delay to configure how long the hook should wait before calling the hook again. This can be configured on all hook types.

We had a Twitch AWS OnAir show this past Friday which dove into CloudFormation hooks, including a re:Post segment where we covered a number of re:Post user questions on this topic. Starting at 34:45.
