LocalStack Resource Library

LocalStack now provides enhanced support for running AWS services in Kubernetes environments. In this presentation from the LocalStack 4.0 community meetup by Simon Walker, we explore how to deploy and manage local AWS resources within Kubernetes clusters with LocalStack, to help developers maintain consistency between development and production environments.The session further covers LocalStack’s Kubernetes integration, including deployment via Helm charts, configuration of services like Lambda and RDS as Kubernetes pods, and networking between components. A demo illustrates provisioning a serverless application (Lambda functions interacting with a MySQL database) using Terraform, with all resources managed within a local Kubernetes cluster.You'll additionally learn the practical approaches for local testing and infrastructure emulation by moving from Docker to Kubernetes-native solutions as well as upcoming features, including broader service support and new container runtime options.## Resources- Documentation: https://docs.localstack.cloud/user-guide/localstack-enterprise/kubernetes-executor/- Get access: https://www.localstack.cloud/contact

About a year ago we have released the first version of LocalStack Extensions: Extensions are a powerful mechanism to plug additional functionality into LocalStack - ranging from additional service emulators, to value-add features like Chaos Engineering, request logging, cloud resource replication/proxying, and more.Over the last couple of months we have been experimenting with a LocalStack Snowflake emulator extension, which allows to develop and test your Snowflake data pipelines entirely on your local machine!In this talk, Waldemar discusses and demonstrates how you can develop your Snowflake data pipelines locally with LocalStack.

Terraform 1.6 introduced native Terraform tests, but running them against real cloud resources leads to long deployment times and unnecessary costs. With LocalStack's Terraform integration (tflocal), you can validate configurations locally while closely emulating real cloud behaviour. By combining Terraform tests with LocalStack, developers can run integration tests in CI/CD environments, test event-driven serverless workflows, and establish a rapid feedback loop for cloud development.In this presentation, Harsh Mishra provides a hands-on demo of Terraform testing with LocalStack, exploring how to configure tests, validate infrastructure locally, and reduce costs and complexity while improving confidence in deployments.## Resources- Blog: https://blog.localstack.cloud/efficient-infrastructure-testing-localstack-terraform-tests-framework/- Documentation: https://developer.hashicorp.com/terraform/language/tests- tflocal: https://docs.localstack.cloud/user-guide/integrations/terraform/#tflocal-wrapper-script

LocalStack enables organizations to automate their application testing and integration process through DevOps practices, such as continuous integration (CI). LocalStack allows organizations to move away from complicated AWS testing and staging environments by enabling a key component of testing and delivering cloud-native applications.To further automate the process, we use Infrastructure-as-Code (IaC) frameworks like Terraform that allow you to create your resources declaratively and apply those resources. Testing your Terraform modules against the real AWS cloud can be time-consuming and costly and can make you run into the risk of dangling resources after an unsuccessful CI run. Using LocalStack to emulate a mock ephemeral AWS infrastructure on CI pipelines allows you to work on the same functionality the real AWS cloud provides while cutting down testing costs and deployment times.In this session, Jim Sheldon, Senior Developer Advocate at Harness, will demonstrate how to use LocalStack to test Terraform modules on Harness CI. Harness CI allows you to create software pipelines that will enable you to check out your code, build the software, run your tests, and validate every code change. We wind up the session with updates about the all-new LocalStack release!

In this hands-on session, you’ll learn how to level up your serverless development by integrating the AWS Toolkit for VS Code with LocalStack — enabling faster Lambda development, debugging, and testing without needing a live AWS account.👨‍💻 Featuring:Joel Scheuner, Senior Software Engineer at LocalStack, will show you how to:✅ Configure the AWS Toolkit for VS Code to connect with LocalStack✅ Deploy and test Lambda functions locally with full AWS emulation✅ Set breakpoints and debug functions right from your IDE✅ Iterate quickly on code changes with minimal setup overheadYou’ll also hear from an AWS engineer sharing real-world insights and best practices for modern serverless workflows.Whether you’re new to serverless or already deep in AWS development, this session will help you code with confidence and streamline your Lambda workflow from start to finish — all from your laptop.

LocalStack is a cloud service emulator designed for local development and testing of cloud applications. With LocalStack, you can test AWS CloudWatch metric alarms, to get notified on infrastructure failures — all on your local machine!In this video, you will learn how you can use a CloudWatch metric alarm to get notified automatically when your Lambda function invocations fail. You will also set up an email notification using the Simple Email Service (SES) and our Mailhog extension.## Resources• CloudWatch Docs: https://docs.localstack.cloud/user-guide/aws/cloudwatch/• LocalStack Extensions: https://docs.localstack.cloud/user-guide/extensions/• Mailhog extension: https://pypi.org/project/localstack-extension-mailhog

Testing in the cloud = slow builds, fragile staging, surprise bills.Let’s talk about how developers are flipping the script and using local cloud environments to test smarter, faster, and cheaper without breaking production.Bonus: You’ll learn how LocalStack lets you simulate AWS on your machine. Game changer.

Why wait for the cloud to test your app? In this episode, we’ll write and run an integration test to validate our LocalStack app. You’ll learn how to upload a file, trigger the Lambda-SQS-DynamoDB flow, and assert the results all locally.

Want to modernize your CI/CD workflows? 🚀 In this session, Jason McCallister introduces Dagger, the open-source programmable CI/CD engine that’s redefining how we build, test, and ship software.You'll learn:- What makes Dagger different from traditional CI/CD tools- How to write pipelines as code and run them locally- How to compose reusable, testable pipeline components- Real-world examples of solving CI headaches with Dagger- Integration tips with Docker, Kubernetes, and beyondWhether you’re a DevOps pro, platform engineer, or just tired of brittle YAML, this talk will show you how Dagger helps you ship faster and smarter.
