# 1. SYSTEM PACKAGES
#    - curl is required for the native Claude Code bash installer
#    - nodejs / npm / pnpm are NO LONGER needed for Claude Code itself,
#      but keep them if your project (e.g. Laravel front-end) needs them.
#      Remove those three lines if you don't need Node in the container.
#    - libgcc / libstdc++ / ripgrep are required by the native binary on
#      Alpine (musl-based). Without these the installer will fail.

# ---------------------------------------------------------------------------
# 2. INSTALL COMPOSER (essential for PHP)
# ---------------------------------------------------------------------------
RUN curl -sS https://getcomposer.org/installer | php -- \
    --install-dir=/usr/local/bin --filename=composer


# ---------------------------------------------------------------------------
# 3. NON-ROOT USER
#    Create a user whose UID/GID matches your host user so that any files
#    written inside the container are owned by YOU on the host, not root.
#
#    HOW TO USE:
#      Pass --build-arg HOST_UID=$(id -u) --build-arg HOST_GID=$(id -g)
#      when you run `docker build`, or hard-code the values below.
#
#    Example build command:
#      docker build \
#        --build-arg HOST_UID=$(id -u) \
#        --build-arg HOST_GID=$(id -g) \
#        -t my-claude-image .
#
#    Example run command (mount your project into /app):
#      docker run --rm -it \
#        -v "$(pwd)":/app \
#        -e ANTHROPIC_API_KEY="$ANTHROPIC_API_KEY" \
#        my-claude-image
# ---------------------------------------------------------------------------
ARG HOST_UID=1000
ARG HOST_GID=1000

RUN addgroup -g "${HOST_GID}" brian \
    && adduser -D -u "${HOST_UID}" -G brian -s /bin/bash brian


# ---------------------------------------------------------------------------
# 4. INSTALL CLAUDE CODE (native bash installer – Anthropic recommended)
#    The native binary:
#      • Requires NO Node.js
#      • Auto-updates in the background
#      • Installs to ~/.local/bin (per-user, no sudo required)
#
#    On Alpine the installer needs USE_BUILTIN_RIPGREP=0 because the
#    bundled ripgrep binary is glibc-linked; we installed ripgrep via apk
#    above instead.
#
#    We switch to the brian for the install so the binary lands in
#    /home/brian/.local/bin (not /root/.local/bin).
# ---------------------------------------------------------------------------
USER brian
ENV HOME=/home/brian
ENV USE_BUILTIN_RIPGREP=0

RUN curl -fsSL https://claude.ai/install.sh | bash

# Make sure the installed binary is on PATH for subsequent RUN steps and
# at container runtime.
ENV PATH="/home/brian/.local/bin:${PATH}"

# ---------------------------------------------------------------------------
# 5. APP DIRECTORIES
#    Create persistent-data dirs as the non-root user so Claude Code can
#    read/write its config without permission errors.
# ---------------------------------------------------------------------------
RUN mkdir -p /home/brian/.config/claude-code \
    && mkdir -p /home/brian/.ssh \
    && mkdir -p /home/brian/app


# ---------------------------------------------------------------------------
# 5.1 DIRECTORY PERMISSIONS
#    Adjust permissions on some directories as needed.
# ---------------------------------------------------------------------------
RUN chmod 700 /home/brian/.ssh


# ---------------------------------------------------------------------------
# 6. WORKDIR & SHELL
# ---------------------------------------------------------------------------
WORKDIR /home/brian/app

SHELL ["/bin/bash", "-c"]


# ---------------------------------------------------------------------------
# 7. DEFAULT COMMAND
# ---------------------------------------------------------------------------
CMD ["claude"]
