Today, we’re excited to announce the release of Docker Build checks with Docker Desktop 4.33. Docker Build checks help your team learn and follow best practices for building container images. When you run a Docker Build, you will get a list of warnings for any check violations detected in your build. Taking a proactive approach and resolving Build warnings and issues early will save you time and h
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
* Only CVE-2024-21626 and CVE-2024-24557 were fixed in Moby 24.0.9. If you are unable to update to an unaffected version promptly after it is released, follow these best practices to mitigate risk: Only use trusted Docker images (such as Docker Official Images). Don’t build Docker images from untrusted sources or untrusted Dockerfiles. If you are a Docker Business customer using Docker Desktop and

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

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
We apologize. We did a terrible job announcing the end of Docker Free Teams. UPDATE: As of March 24, 2023, Docker has reversed its decision to sunset the “Docker Free Team” plan. Read our new blog post for details. We apologize for how we communicated and executed sunsetting Docker “Free Team” subscriptions, which alarmed the open source community. For those of you catching up, we recently emailed
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
This guest post is written by Prakhar Srivastav, Senior Software Engineer at Google. Anyone who’s built their own containers, either for local development or for cloud deployment, knows the advantages of keeping container sizes small. In most cases, keeping the container image size small translates to real dollars saved by reducing bandwidth and storage costs on the cloud. In addition, smaller ima
We’re excited to announce that Docker Hub can now help you distribute any type of application artifact! You can now keep everything in one place without having to leverage multiple registries. Before today, you could only use Docker Hub to store and distribute container images — or artifacts usable by container runtimes. This became a limitation of our platform, since container image distribution
