AWS open source news and updates, #110

April 29th, 2022 - Instalment #110

Newsletter #110.

Welcome to edition #110 of the AWS open source newsletter. It has been a busy week, with the AWS Summit London happening this week (where I was lucky enough to do a session on Apache Airflow) meaning I am publishing this a little later than I had planned. We have more great new projects this week, including a project that helps make it easier to deploy your static and dynamic applications, a tool that provides help in managing the long term health of your AWS Data Lake, a cool project to help you replicate data from a Kinesis Data Stream across regions, a nice CloudWatch dashboard widget that summarises your CloudFormation stacks, and many more - so check them out.

This week also features content covering a broad range of open source topics, including AWS CloudFormation Guard, KubeFlow, Semgrep, Steampipe, Terraform, Apache Spark, Kubernetes, Karpenter, PostgreSQL, Linux, Istio, Apache Airflow, Hugging Face, ROS and many more. There a strong theme of security compliance in some of the topics, so if this is something you are looking at how open source can help, you will find these helpful.

Video content this week includes a detailed look at AWS EKS Blueprints for Terraform, as well as an updated on the latest AWS CDK release and a zero to hero workshop if you want to get started (and its in Python, yay!). Finally, don't forget to check out the events. KubeCon is just around the corner, but we are also in the AWS Summit season, and we will have plenty of great open source content so hope to see you.

Do you have an interesting open source project you want to share?

As always, if you are working on anything interesting you would like me to include in this weekly round up, please drop me a line at

Celebrating open source contributors

The articles posted in this series are only possible thanks to contributors and project maintainers and so I would like to shout out and thank those folks who really do power open source and enable us all to build on top of what they have created.

So thank you to the following open source heroes: Mahalingam Sivaprakasam, Abhinav Krishna Vadlapatla, Matthew Bonig, Ed Miller, Melody Yang, Kinnar Kumar Sen, Dakota Riley, David Boeke, Bob Tordella, Jon Udell, Nathan Wallace, Kanwaljit Khurmi, Meghna Baijal, Suraj Kota, Joaquin Manuel Rinaudo, Laimonas Sutkus and Hassan Tahhan.

Make sure you find and follow these builders and keep up to date with their open source projects and contributions.

Latest open source projects



content-delivery-demo this project from Hassan Tahhan demonstrates how to accelerate distribution of your static and dynamic content in a secure, scalable, and repeatable way using Amazon CloudFront, Amazon S3, Amazon EC2, Application Load Balancer (ALB), Amazon VPC, and AWS CloudFormation. Other AWS services used are Amazon CloudWatch, AWS Lambda, AWS IAM, and AWS SDK for Python (Boto3).

Demos, Samples and Workshops


kinesis-data-streams-replication-using-kinesis-data-analytics-studio It can be desirable to replicate data from a Kinesis Data Stream in Region A to Region B for many reasons including Disaster Recovery Resiliency, migration to another region, or simply making data available in both regions for separation of concerns. In this repository, we showcase how to replicate data between regions using Kinesis Data Analytics Studio, a managed Apache Flink SQL interactive environment using Apache Zeppelin.

AWS and Community blog posts


Steampipe is an open source tool under the AGPLv3 license for querying cloud APIs in a universal way and reasoning about the data in SQL. David Boeke, Bob Tordella, Jon Udell, and Nathan Wallace have come together to pen the post, Compliance auditing with Steampipe and SQL. This is a follow up to a previous post that explored how to use Steampipe to query your AWS environments, and in this post they share how Steampipe’s Compliance “mod” enables you to query your AWS infrastructure to check against a number of compliance with regulatory frameworks. This is a really cool project, so you should check this out. [hands on]


Semgrep (short for Semantic Grep) is a fast, lightweight, and open-source static analysis tool for finding bugs and automating code reviews. In the blog post, Using SemGrep to find security issues and misconfigurations in AWS Cloud Development Kit projects, Dakota Riley, Principal Security Engineer at Aquia, explores how you can apply static code analysis with Semgrep to the AWS Cloud Development Kit to find security misconfigurations. This is a great post, and I am going to try out some of these against my own CDK stacks to see how well they faire. [hands on]

AWS CloudFormation Guard

AWS CloudFormation Guard is an open-source general-purpose policy-as-code evaluation tool. It provides developers with a simple-to-use, yet powerful and expressive domain-specific language (DSL) to define policies and enables developers to validate JSON or YAML formatted structured data with those policies. In the post, Extend your pre-commit hooks with AWS CloudFormation Guard, Joaquin Manuel Rinaudo shows you how to extend your Git hooks to validate your AWS CloudFormation templates against policy-as-code rules by using AWS CloudFormation Guard. This can help you verify that your code follows organisational best practices for security, compliance, and more by preventing you from commit changes that fail validation rules. [hands on]

BearCam Project

AWS Community Builder Ed Miller has put together his first post in the AWS Community Builder channel on, looking at a new project that he is going to open source that certainly got my attention. The BearID project is an initiative to explore how noninvasive technologies can help identify and monitor bears, facilitating their conservation. Ed has laid out some of his thinking for his idea, but is looking for feedback and potentially collaborators. If you love bears, and have some spare cycles, why not get in touch. Read the post, BearCam Companion.

Apache Spark

Melody Yang and Kinnar Kumar Sen share how you can run Apache Spark workloads faster and cheaper with Amazon EMR on EKS when compared to Apache Spark on Amazon EKS, without making any application changes, in their post, Amazon EMR on Amazon EKS provides up to 61% lower costs and up to 68% performance improvement for Spark workloads. Using the TPC-DS datasets at 3 TB scale to benchmark, this is worth while reading if you are running any Apache Spark workloads on AWS.

Kubeflow is the open-source machine learning (ML) platform dedicated to making deployments of ML workflows on Kubernetes simple, portable and scalable. In the post, Build and deploy a scalable machine learning system on Kubernetes with Kubeflow on AWS, Kanwaljit Khurmi, Meghna Baijal, and Suraj Kota demonstrate Kubeflow on AWS (an AWS-specific distribution of Kubeflow) and the value it adds over open-source Kubeflow through the integration of highly optimised, cloud-native, enterprise-ready AWS services. [hands on]

Addressing latency and data transfer costs on EKS using Istio takes a look at data transfer charges in your Amazon EKS clusters. Mahalingam Sivaprakasam and Abhinav Krishna Vadlapatla explore one approach using Itsio that might help reduce costs while operating your workloads on Amazon EKS at production scale. [hands on]

Quick updates

Amazon Linux 2022

Amazon Elastic Container Service (Amazon ECS) today announced the public preview of the Amazon ECS-optimized Amazon Linux 2022 Amazon Machine Image (AMI). Amazon Linux 2022 (AL2022) is the next generation of Amazon Linux from Amazon Web Services (AWS) that is designed to provide a secure, stable, and high-performance execution environment to develop and run your cloud applications. Starting with AL2022, a new Amazon Linux major version will be available every two years and each major version will be supported for five years. Amazon ECS will publish Amazon ECS-optimized AMIs to support the same 2-year release and 5-year support cycle for every new major Amazon Linux version. The two-year major release cycle helps you keep your software up-to-date while the five year support commitment for each major release gives you the stability you need to manage long project lifecycles.

AL2022 is based on the Fedora project and provides frequent and flexible quarterly updates. AL2022 also locks to a specific version of the Amazon Linux package repository, which gives you control over how and when you absorb updates. In addition, AL2022 also comes with Security-Enhanced Linux (SELinux) policies for additional isolation. Furthermore, the Amazon ECS-optimized AL2022 AMI now uses cgroupsV2 as the default kernel setting for managing Task and container resources, which enables improved memory management.


Amazon Elastic Kubernetes Service (EKS) is announcing v0.9.0 of the Karpenter open-source cluster autoscaling project. Karpenter is a flexible, high-performance Kubernetes cluster autoscaler that helps improve application availability and resource utilisation. Karpenter v0.9.0 adds supports for Kubernetes podAffinity and podAntiAffinity scheduling constraints, which increases its compatibility with popular third-party Helm charts and expands support for high-availability use cases.

Karpenter v0.9.0 is the latest release since the project’s launch at re:Invent 2021. On January 7, 2022, Karpenter v0.5.4 added support for volume topology aware scheduling, enabling its use with stateful Kubernetes workloads. On March 14, 2022, Karpenter v0.7.0 made it easier to customise the compute provisioned by removing the need for custom EC2 launch templates, including when using Bottlerocket as the OS. With the v0.9.0 release, Karpenter fully supports workloads that use Kubernetes podAntiAffinity to achieve better availability by spreading pods across multiple hosts or availability zones.


Matthew Bonig has put together a short video to share news about release 2.21 of AWS CDK, covering highlights and showing examples of some of the new features in the AWS CDK.

Videos of the week

AWS EKS Blueprints for Terraform

The Containers from the Couch crew take a look at the new Amazon EKS Blueprints for Terraform modules and how they can help you manage your Kubernetes clusters.

AWS CDK Workshop - From Zero to Hero

This online workshop is presented by Laimonas Sutkus, the CTO of Biomapas and he shows you how to get started with AWS CDK. It is a long session, but covers a lot of topics and uses Python which makes me happy as I typically see TypeScript workshops, so if you are a Python developer, this becomes a must watch.
