Defang Compose Update

Hey folks! We've got another batch of updates to share with you about what the Defang team has been working on over the past month. We're committed to improving your deployment experience, so let's take a look at what's new.

Windows Experience Improvements

For our Windows users out there, we've made some changes to make your Defang experience even smoother:

  • You can now install Defang using winget, the Windows Package Manager, for a streamlined setup
  • We've introduced a signed binary for added security and peace of mind

Deploying your apps from Windows just got a little bit nicer.

One-click Deploy

We've added a new feature that will make it even easier to get started with Defang. We've created a flow where each sample provides a button that allows you to immediately deploy a template with a GitHub action which will automatically deploy the sample to the Defang Playground. That means you can easily make changes by committing them to your brand new repo, and everything automatically updates in the Playground. It's a great way to get started with Defang and start experimenting with your own projects.

Managed Redis Updates

We first introduced this last month, but we've since rolled it out to everyone. We also added a sample that showcases the power of managed Redis: BullMQ with Redis. It demonstrates how you can use BullMQ and BullBoard with a managed Redis instance to create a powerful job queue system so you can easily build robust, scalable applications in AWS with Defang.

Updated Samples

We've updated our sample projects to showcase how to use them with Defang, including:

Check them out if you're looking for some inspiration or a starting point for your own projects.

CLI Updates

We're always looking for ways to enhance the CLI experience. Here's what's new:

  • npx defang automatically checks to always have the latest version of the CLI
  • The output during defang compose up has been streamlined to focus on the most important information
  • defang tail now supports listening to specific services, making it easier to troubleshoot issues
  • We've improved hints and error messages to better guide you when something goes wrong
  • The CLI now has improved color support for light theme terminals, making it easier on the eyes

It's the small refinements that can make a big difference in your workflow.

Other Updates

Here are a few more things that didn't quite fit with the rest:

  • Visibility into ECS deployment events in BYOC tail logs
  • Improvements to ACME certificate generation

Keep an eye out for these updates in the near future.


As always, we'd love your help shaping the future of Defang, so let us know what you'd like to see next. Happy deploying! 🚀

Defang Compose Update

Hey folks! We’re back with another exciting update about Defang. Our team has been working hard to bring you new features and improvements so you can get deploying faster. Here’s a rundown of what we’ve been up to this month:

Samples, samples, samples!

We've been cranking out samples like there's no tomorrow. We've published samples to get you up and running with FastAPI, Elysia, Angular, React, Svelte, Sveltekit, Sails.js, Phoenix, and more. You can filter through them on the Defang homepage. Check out our video about all the new samples and functionality.

Start from a sample in seconds

With all this work we've been putting into samples, we realized it would be pretty awesome if you could clone a sample faster. So we updated the CLI. Now, if you run defang generate you'll be able to filter through the samples and choose one. You can also filter through the samples on the Defang homepage and clone any of them with a simple command like defang new sveltekit.

Sample templates

If you look through our GitHub organization, you'll start seeing loads of repos with the structure sample-<sample_name>-template. If you open them, you can create a new repo by clicking this button:

Not only will that create a new repo based on the sample in your account, but if you've used Defang before (and accepted the Terms and Conditions) it will automatically deploy it to the playground so you can start playing with Defang immediately.

ACME for BYOD

We’re excited to announce that ACME support is now available for Bring Your Own Domain (BYOD) in both Bring Your Own Cloud (BYOC) and Playground. This means you can easily add Let's Encrypt certificates to your custom domains, regardless of where your DNS is hosted. Defang will handle the certificate generation and automatic renewal for you. Nice and easy.

Warnings for Stateful Services

To help you avoid potential pitfalls, we’ve added warnings against deploying stateful services with Defang, since you shouldn't actually be deploying anything stateful with Defang. For example, we'll warn you if you try to deploy services with images like postgres:<version>, redis:<version>, minio:<version>, etc.

In the near future we will be offering ways to run some stateful services using cloud providers' managed offerings. For example Redis, Postgres, and S3. Speaking of which...

Managed Redis!

Redis is such a versatile tool that can help with so many different use cases. So we've introduced Managed Redis! You can now specify the Redis image in your compose.yaml file and indicate that you want it managed by your cloud provider using x-defang-redis: true in your service definition.

Load Testing

To make sure Defang is ready for loads of new users, we've been doing a lot of load testing. This is going to help us identify and address potential bottlenecks so we can make sure that Defang scales efficiently and handles all you new users smoothly.

Upgraded Kaniko

We’ve upgraded our Kaniko integration to version 1.23.0 to improve your container build experience. The new version comes with several bug fixes that enhance stability and performance. This means faster and more reliable builds for your applications.

Upcoming Features

We’re not stopping here! Here’s a sneak peek at what’s coming soon:

Managed Postgres

Building on the momentum of Managed Redis, we’re introducing Managed Postgres. Soon you’ll be able to easily integrate a managed Postgres database into your deployment!

BYOC ECS Lifecycle Events

Defang runs your services with ECS, and we're working on making it clearer what's happening under the hood.


Stay tuned for more updates and improvements. As always, we appreciate your feedback and are committed to making Defang the easiest way to deploy your applications to the cloud. Go deploy something awesome! 🚀
