Chainguard image for Docker in Docker (DinD), allowing you to run Docker within a container.

Chainguard Containers are regularly-updated, secure-by-default container images.

Download this Container Image

For those with access, this container image is available on cgr.dev:

docker pull cgr.dev/ORGANIZATION/docker-dind:latest

Be sure to replace the ORGANIZATION placeholder with the name used for your organization's private repository within the Chainguard Registry.

Compatibility Notes

The Chainguard Docker Image is comparable to the official Docker Image from Docker Hub. However, the Chainguard image contains only the minimum set of tools and dependencies needed to function. This means it doesn't include things like a package manager.

Getting Started

To use the image you can either run in privileged mode after mounting sock path or run the image with --privileged flag As an example of how you can use this image, run the container in detached mode by passing the -d argument and bind the Docker socket:

docker run --rm -it -d -v /var/run/docker.sock:/var/run/docker.sock --name my-dind $IMAGE_NAME sh

Following that, you can interact with the container using docker exec:

docker exec -it my-dind docker info
docker exec -it my-dind docker version
docker exec -it my-dind docker images
docker exec -it my-dind docker run --rm cgr.dev/chainguard/busybox echo "Hello from BusyBox"

Another example of how you can use this image, run the container in privileged mode by passing the --privileged flag:

docker run --name my-privileged-dind --rm --privileged -d $IMAGE_NAME

Following that, you can interact with the container using docker exec:

docker exec -it my-dind docker info
docker exec -it my-dind docker version
docker exec -it my-dind docker images
docker exec -it my-dind docker run --rm cgr.dev/chainguard/busybox echo "Hello from BusyBox"

What are Chainguard Containers?

Chainguard's free tier of Starter container images are built with Wolfi, our minimal Linux undistro.

All other Chainguard Containers are built with Chainguard OS, Chainguard's minimal Linux operating system designed to produce container images that meet the requirements of a more secure software supply chain.

The main features of Chainguard Containers include:

• Minimal design, without unnecessary software bloat
• Daily builds to ensure container images are up-to-date with available security patches
• High quality build-time SBOMs attesting to the provenance of all artifacts within the image
• Verifiable signatures provided by Sigstore
• Reproducible builds with Cosign and apko (read more about reproducibility)

For cases where you need container images with shells and package managers to build or debug, most Chainguard Containers come paired with a development, or -dev, variant.

In all other cases, including Chainguard Containers tagged as :latest or with a specific version number, the container images include only an open-source application and its runtime dependencies. These minimal container images typically do not contain a shell or package manager.

Although the -dev container image variants have similar security features as their more minimal versions, they include additional software that is typically not necessary in production environments. We recommend using multi-stage builds to copy artifacts from the -dev variant into a more minimal production image.

Need additional packages?

To improve security, Chainguard Containers include only essential dependencies. Need more packages? Chainguard customers can use Custom Assembly to add packages, either through the Console, chainctl, or API.

To use Custom Assembly in the Chainguard Console: navigate to the image you'd like to customize in your Organization's list of images, and click on the Customize image button at the top of the page.
