Get started with the latest updates for Dockerfile syntax (v1.7.0) | Docker
Dockerfiles are fundamental tools for developers working with Docker, serving as a blueprint for creating Docker images. These text documents contain all the commands a user could call on the command line to assemble an image. Understanding and effectively utilizing Dockerfiles can significantly streamline the development process, allowing for the automation of image creation and ensuring consiste
Announcing Docker Compose Watch GA Release | Docker
Docker Compose Watch, a tool to improve the inner loop of application development, is now generally available. Hot reload is one of those engineering workflow features that’s seemingly minor and simple but has cumulative benefits. If you can trust your app will update seamlessly as you code, without losing state, it’s one less thing pulling your focus from the work at hand. You can see your fronte

Docker Compose Modularity with `include` | Docker
This blog post discusses a feature available now in Compose v2.20.0 and in our Docker Desktop 4.22 release. The docker command line supports many flags to fine-tune your container, and it’s difficult to remember them all when replicating an environment. Doing so is even harder when your application is not a single container but a combination of many containers with various dependency relationships

We're no longer sunsetting the Free Team plan | Docker
After listening to feedback and consulting our community, it’s clear that we made the wrong decision in sunsetting our Free Team plan. Last week we felt our communications were terrible but our policy was sound. It’s now clear that both the communications and the policy were wrong, so we’re reversing course and no longer sunsetting the Free Team plan: If you’re currently on the Free Team plan, you
Generating SBOMs for Your Image with BuildKit | Docker
The latest release series of BuildKit, v0.11, introduces support for build-time attestations and SBOMs, allowing publishers to create images with records of how the image was built. This makes it easier for you to answer common questions, like which packages are in the image, where the image was built from, and whether you can reproduce the same results locally. This new data helps you make inform
How Docker Desktop Networking Works Under the Hood | Docker
Modern applications make extensive use of networks. At build time it’s common to apt-get/dnf/yum/apk install a package from a Linux distribution’s package repository. At runtime an application may wish to connect() to an internal postgres or mysql database to persist some state, while also calling listen() and accept() to expose APIs and UIs over TCP and UDP ports. Meanwhile developers need to be
Faster Multi-Platform Builds: Dockerfile Cross-Compilation Guide | Docker
Faster Multi-Platform Builds: Dockerfile Cross-Compilation Guide There are some important changes happening in the software industry. With Apple moving all of their machines to their custom ARM-based silicon and AWS offering the best performance-per-cost ratio with their Graviton2 instances, one can no longer expect that all software only needs to run on x86 processors. If you work with containers
Looking for a Docker Alternative? Consider This. | Docker
Docker recently announced updates and extensions to our product subscriptions. Docker CEO Scott Johnston also posted a blog about the changes. Much of the discussion centered on what the licensing changes mean for users of Docker Desktop, which remains free for small businesses and several other user types, but now requires a paid subscription — starting at $5 per user per month — for professional
Introduction to heredocs in Dockerfiles | Docker
Guest post by Docker Community Member Justin Chadell. This post originally appeared here. As of a couple weeks ago, Docker’s BuildKit tool for building Dockerfiles now supports heredoc syntax! With these new improvements, we can do all sorts of things that were difficult before, like multiline RUNs without needing all those pesky backslashes at the end of each line, or the creation of small inline
Changes to Docker Hub Autobuilds | Docker
As many of you are aware, it has been a difficult period for companies offering free cloud compute [1]. Unfortunately, Docker’s Autobuild service has been targeted by the same bad actors, so today we are disappointed to announce that we will be discontinuing Autobuilds on the free tier starting from June 18, 2021. In the last few months we have seen a massive growth in the number of bad actors who
Best practices for using Docker Hub for CI/CD | Docker
According to the 2020 Jetbrains developer survey 44% of developers are now using some form of continuous integration and deployment with Docker Containers. We know a ton of developers have got this setup using Docker Hub as their container registry for part of their workflow so we decided to dig out the best practices for doing this and provide some guidance for how to get started. To support this

Apple Silicon M1 Chips and Docker | Docker
Revealed at Apple’s ‘One More Thing’ event on Nov 10th, Docker was excited to see new Macs feature Apple silicon and their M1 chip. At Docker we have been looking at the new hypervisor features and support that are required for Mac to continue to delight our millions of customers. We saw the first spotlight of these efforts at Apple WWDC in June, when Apple highlighted Docker Desktop on stage. Our
