Multistage builds feature in Dockerfiles enables you to create smaller container images with better caching and smaller security footprint. In this blog post, I’ll show some more advanced patterns that go beyond copying files between a build and a runtime stage, allowing to get most out of the feature. If you are new to multistage builds you probably want to start by reading the usage guide first.

Awesome-Compose: Application samples for project development kickoff
Software systems have become quite complex nowadays. A system may consist of several distributed services, each one providing a specific functionality and being updated independently. Starting the development of a project of such complexity is sometimes time consuming, in particular when you are not already familiar with the software stack you are going to work on. This may be because, most of the time, we need to follow rigorous steps to put together the entire project and if we make a mistake in-between, we may have to start all over again.

First Docker GitHub Action is here!
We are happy to announce that today Docker has released its first Github Action! We’ve been working with GitHub, looking into how developers have been using GitHub Actions with Docker to set up their CI/CD workflows. The standard flows you’ll see if you look around are what you’d expect: building an image, tagging it, logging into Hub, and pushing the image. This is the workflow we’ve aimed to support with our Docker build-push action.

How to deploy on remote Docker hosts with docker-compose
The docker-compose tool is pretty popular for running dockerized applications in a local development environment. All we need to do is write a Compose file containing the configuration for the application’s services and have a running Docker engine for deployment. From here, we can get the application running locally in a few seconds with a single `docker-compose up` command.

Docker Donates the cnab-to-oci Library to cnab.io
Docker helped with the development of all those components, but also worked with Microsoft on the cnab-to-oci library for sharing a CNAB bundle. This library is now used at least by 3 tools: Docker App, Porter and duffle, but also internally in Docker Hub. It successfully demonstrated how to push, pull and share description of a CNAB bundle on a registry. This work will be used as a base for the future CNAB Registries specification.
