【Feat】Automate Docker Image Builds with GitHub Actions

[QwertyJack]

Description:

This PR introduces a new GitHub Actions workflow to automate the Docker image build process. This workflow is configured to automatically trigger whenever the branch is updated, ensuring that a fresh Docker image is built for the latest code.

Key Changes:

• Added GitHub Actions Workflow: A new workflow file (.github/workflows/docker-build.yml or similar) has been added.
• Leverages GitHub Action Templates: The workflow is based on existing GitHub Action templates for Docker image building, ensuring best practices and ease of maintenance.
• Automated Trigger: The workflow is set to run automatically on push events to the branch, providing continuous integration for Docker image creation.

Benefits:

• Continuous Integration: Ensures that a Docker image is always up-to-date with the latest code changes.
• Improved Reliability: Catches build issues early in the development cycle.
• Reduced Manual Effort: Eliminates the need for manual Docker image builds.
• Faster Feedback Loop: Developers get immediate feedback on the Docker build status of their changes.

How to Test:

Push a new commit to this branch, and observe the GitHub Actions tab to confirm the workflow is triggered and completes successfully.

@ant-kurt pls

@QwertyJack thanks for creating this PR - we're talking over a few things internally and have not forgotten this!

Hi - we're not currently planning to officially support a published devcontainer image right now, and if we did it would likely not be one for the Node.js toolchain specifically. We may revisit this decision in the future; note that if we were to publish images, they would likely be derived from the well-known prebuilt devcontainer images.

Thank you for creating this and please keep the feedback coming regarding devcontainers (and Claude Code generally).

Hi, @QwertyJack! I have implemented automatic rebuilding of devcontainer images, thanks to your PR which inspired me.

The image is updated automatically without any changes to the original Dockerfile, every time a .devcontainer is released or when a new version of Claude Code is released (checked once a day).

Until Anthropic starts official support, I decided to automate the build for all enthusiasts.

https://github.com/users/pravorskyi/packages/container/package/claude-code-devcontainer%2Fdevcontainer

Example how it can be used:

FROM ghcr.io/pravorskyi/claude-code-devcontainer/devcontainer:latest

# Example: add Python tooling
USER root
RUN apt-get update && apt-get install -y --no-install-recommends \
    python3-dev build-essential python3-venv \
    && apt-get clean && rm -rf /var/lib/apt/lists/*

ENV VIRTUAL_ENV=/opt/venv
COPY requirements.txt /opt
RUN python3 -m venv "$VIRTUAL_ENV" && \
    . "$VIRTUAL_ENV/bin/activate" && \
    pip install --no-cache-dir -r /opt/requirements.txt
ENV PATH="$VIRTUAL_ENV/bin:$PATH"

USER node
