Latest open source projects

Community

awsbe-site

awsbe-site AWS Community Builder Ualter Otoni Pereira has created this tool written in Go, to help handle AWS Session connections on terminals. It uses your configured AWS Shared Config and Credentials files, and manages Roles to Assume, MFA Token requests, AWS SSO Sign-in, AWS SSO Tokens and the expiration of opened sessions.

aws-lambda-events

aws-lambda-events this open source tool from AWS Community Builder Michael Brewer, provides a collection of resources and tools on the different input and outputs that AWS Lambda expects. You can use this tool to publish your locally defined test events to the Lambda Console, and the project has 100s of different examples and cli tools with examples to help get you started.

task-tree

task-tree this new tool from my friend and former colleague Julio Faerman, looks to help you automate complex maintenance and troubleshooting tasks in cloud computing. One of the things this tool can help you with is to cleanup AWS resources based on a naming prefix. Julio warmly welcomes any contributions and has provided a wish list of things he wants to add to this project.

aws-search-extension

aws-search-extension so I missed this project from Pit, but thanks to the AWS Community Builders who shared this project in our Slack channel. This is a browser plugin that provides a search-extension, providing quick, fuzzy-search results for AWS developers. Includes AWS API, AWS CLI and AWS CloudFormation references, and opens the official AWS documentation page when you select an item. Looks like it is compatible with most browsers (but I only tried with Chrome/Firefox). Once you have it installed, from the tab just type in "ase" and then space, and you will see a new search bar appear. Very nice.

Tools

kubectl-detector-for-docker-socket

kubectl-detector-for-docker-socket this tool will help you detect whether you are using the dockershim that is being removed from Kubernetes 1.24. It is a kubectl plugin to detect if active Kubernetes workloads are mounting the docker socket (docker.sock) volume.

nestjs-s3

nestjs-s3 NestJS is an AWS S3 library allows you to use the AWS SDK v3 in a more friendly and familiar way by providing injectable services for managing things like buckets and objects. There is a great write up from Martin Andreev on the backstory for this project, so make sure you read NestJS AWS S3 – From an idea to reality.

Quick updates

Kubernetes

Amazon Elastic Kubernetes Service (Amazon EKS) now supports using the Amazon EKS console, AWS Command Line Interface (CLI), and EKS API to install and manage the the Amazon Elastic Block Store (EBS) Container Storage Interface (CSI) driver. This launch enables a simple experience for attaching persistent storage to an EKS cluster. The EBS CSI driver provides a CSI interface used by container orchestrators to manage the lifecycle of Amazon EBS volumes. Since announcing preview, EKS add-ons support now includes Windows compatibility, dynamic snapshotting and resizing of EBS volumes via the Kubernetes API, and backwards compatibility with the in-tree EBS driver. The EBS CSI driver can be installed, managed, and updated directly through the EKS console, CLI, and API. You can see available add-ons and compatible versions in the EKS API, select the version of the add-on you want to run on your cluster, and configure key settings such as the IAM role used by the add-on when it runs. Using EKS add-ons you can go from cluster creation to running applications in a single command and easily keep tooling in your cluster up to date.

Jens-Uwe Walther and Jesse Butler have put together this blog post, Amazon EBS CSI driver is now generally available in Amazon EKS add-ons dives deeper into this announcement, together with some of the historical and background of the project before demonstrating how to create an Amazon EBS CSI EKS add-on, using it in the context of a Kubernetes workload. [hands on]

PostgreSQL

Following the announcement of updates to the PostgreSQL database by the open source community, we have updated Amazon Aurora PostgreSQL-Compatible Edition to support PostgreSQL 13.6, 12.10, 11.15, and 10.20. These releases contain bug fixes and improvements by the PostgreSQL community. Refer to the Aurora version policy to help you to decide how often to upgrade and how to plan your upgrade process. In addition, Babelfish for Aurora PostgreSQL version 1.2.0 has been released for PostgreSQL 13.6, providing improvements in support for GRANT, REVOKE , ROWVERSION , JSON_QUERY and more.

Also new last week was news that Amazon Aurora PostgreSQL-Compatible Edition now supports a foreign data wrapper that can connect to databases that use the Tabular Data Stream (TDS) protocol, such as Sybase databases and Microsoft SQL server. You can use this foreign data wrapper to connect to data sources in other databases eliminating the need to replicate or copy data.
