Anthropic ships a .devcontainer with Claude Code but no image. So you have to build it yourself, every time. You build it Monday. Claude Code updates Tuesday. .devcontainer changes Wednesday. By Thursday you're questioning your life choices. Fuck that. I automated it.

This repo builds it for you daily and pushes to GHCR. Zero modifications.

Use as a base image in your own Dockerfile:

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

Or in devcontainer.json directly, if you don't need to extend the image and don't use Claude Code's .devcontainer as your main devcontainer:

{
  "name": "Claude Code",
  "image": "ghcr.io/pravorskyi/claude-code-devcontainer/devcontainer:latest"
}

Pin to a specific Claude Code version instead of latest:

ghcr.io/pravorskyi/claude-code-devcontainer/devcontainer:claude-code-1.0.20

A daily CI job checks for two things:

• New Claude Code releases on npm
• Changes to .devcontainer in the upstream repo

When either is detected, it builds and pushes the image to GHCR.

The claude-code submodule points to the official Anthropic repo. The Dockerfile comes from there, unmodified. The CI workflows are short and readable. Every image is labeled with the exact source commit it was built from.

You can verify: docker inspect ghcr.io/pravorskyi/claude-code-devcontainer/devcontainer:latest and check org.opencontainers.image.source and org.opencontainers.image.revision.

This is a personal repo by some random dude (hi!) on the internet. GitHub Actions could be modified to inject anything into the image between builds. The submodule proves the source, not the output. If this matters to you, fork the repo and build your own image — the CI is all there.
