S3 Cross Account Adventures

Update October 2020 AWS has finally added a feature to solve our problem, now all that’s missing is CloudFormation support :-) Amazon S3 Object Ownership is available to enable bucket owners to automatically assume ownership of objects uploaded to their buckets In the process of building a data lake in a multi-account environment, we encountered a problem that didn’t fit into our existing mental model of how S3 and S3 cross account permissions work.

Building a static website with Hugo and the CDK

Building a static website with Hugo and the CDK If you ever wanted to host your personal website or blog on AWS this article is right for you. We’re going to build a static website with Hugo, CodeBuild and CodePipeline and host it using CloudFront and S3. We will set up everything you need to build and deploy new versions of the Website.

The case of the missing bucket notifications

The case of the missing bucket notifications A few days ago I was trying to do something quite simple. I wanted to send S3 Put-Events to multiple Lambda functions for processing. This is a pretty common pattern. To implement it you have to use an architecture such as the one you can see in the title image above. This is because S3 has a limit on the event handlers (notification targets) per event type of exactly one.

More Tools - CDK Examples

We need more CDK examples In this github repo we focus on examples for every day work. While there are some nice examples for the fancy stuff like fargate, ecs and so on in aws-cdk-examples/typescript at master · aws-samples/aws-cdk-examples · GitHub, i felt that basic examples where missing. So we created GitHub - tecracer/cdk-templates: Templates for aws cdk

Getting around circular CloudFormation Dependencies: S3-Event-Lambda-Role

Getting around circular CloudFormation dependencies Several posts complain about the inability of CloudFormation to apply a Lambda event function to an S3 Bucket with an dynamically generated name. The standard UseCase is an S3 Bucket with a Lambda event notification. In this special case the Bucket has a dynamically generated name. This cannot be done by pure CloudFormation! How to work around this circular depency? Let me show you an easy way:

Große Wolken - CloudFormation Makros

How to: CloudFormation Makro CloudFormation vermisst gegenüber Terraform einige Funktionen, die das Erstellen von Infrastruktur vereinfachen können. Das ist grundsätzlich korrekt, allerdings gibt es in CloudFormation die Möglichkeit, sich selber um den Einbau solcher Funktionen zu kümmern. Das geht mithilfe sogenannter CloudFormation Makros. CloudFormation Makros sind Funktionen, die wir per CloudFormation erstellen können und dann in weiteren CloudFormation Templates einbauen und verwenden können. Wir zeigen dies am Beispiel einer Count Funktion.
