⁠Software Tags and Versioning

Learn about our tagging policy and the difference between rolling tags and immutable tags on our documentation page⁠⁠.

⁠Software Bill of Materials (SBOM)

Starting with version 0.25.2, a Software Bill of Materials (SBOM) in SPDX format is generated for every image at build time and attached directly to the image in Docker Hub as an OCI attestation, available for the edge, latest and versioned tags. Retrieve it with

• docker scout sbom sommerfeldio/devcontainer:latest or
• docker buildx imagetools inspect sommerfeldio/devcontainer:latest --format "{{ json .SBOM }}".

The same SBOM is also attached as a downloadable asset on each GitHub release⁠.

⁠Usage

The easiest way to use this image is by adding a Dockerfile to your repository's .devcontainer folder and extending sommerfeldio/devcontainer.

FROM sommerfeldio/devcontainer:latest
LABEL maintainer="[email protected]"

This sommerfeldio/devcontainer image is based on mcr.microsoft.com/devcontainers/base:ubuntu-24.04⁠ and is configured to run as the non-root user vscode by default. File permissions and mounted volumes will be owned and accessed by the vscode user (uid = 1000, gid = 1000).

{
    "name": "project-name",
    "build": {
        "dockerfile": "Dockerfile"
    },

    "customizations": {
        "vscode": {
            "settings": {},
            "extensions": [
                "ms-azuretools.vscode-docker",
                "github.vscode-github-actions",
                "redhat.vscode-yaml"
            ]
        }
    },

    "features": {
        "ghcr.io/devcontainers/features/docker-in-docker:4.0.0": {
            "moby": false
        }
    }
}

This approach provides several benefits:

• Ensures that pipelines can validate the Devcontainer setup.
• Allows Dependabot to track updates.
• Makes it easy to extend the image with additional tools as needed.
