# ------------------------------------------------------------------
# 1. Base image
# ------------------------------------------------------------------
# We use a slim Debian base so we can use apt‑get to pull every
# component in one go.  Debian Bookworm contains all the
# packages we need (nodejs 18, redis, nginx, php8‑fpm, etc.).
# ------------------------------------------------------------------
FROM php:8.0-apache

# ------------------------------------------------------------------
# 2. Build arguments – handy if you want to change the port numbers
#    without touching the Dockerfile
# ------------------------------------------------------------------
ARG REDIS_PORT=6379
ARG NODE_PORT=3000
ARG PHP_PORT=8080
ARG NGX_PORT=80

ENV REDIS_PORT=${REDIS_PORT}
ENV NODE_PORT=${NODE_PORT}
ENV PHP_PORT=${PHP_PORT}
ENV NGX_PORT=${NGX_PORT}

# ------------------------------------------------------------------
# 3. Install all the system packages we need
# ------------------------------------------------------------------
RUN apt-get update && \
    DEBIAN_FRONTEND=noninteractive apt-get install -y \
        curl gnupg ca-certificates \
        nodejs npm \
        redis-server \
        nginx \
        supervisor \
    && apt-get clean && rm -rf /var/lib/apt/lists/*

# ------------------------------------------------------------------
# 4. Prepare the working directories
# ------------------------------------------------------------------
# Node app
WORKDIR /app
COPY web/node_server/package.json ./
RUN npm install
COPY web/node_server/ ./

# Web‑dashboard static files
COPY web/html /var/www/html/

# API settings file
COPY cosmostat_settings.yaml /app/cosmostat_settings.yaml

# Nginx config – you can keep the same file you used for the
# proxy service in the compose file.  It will proxy 3000 (WS)
# and 8080 (PHP) to the local container.
COPY web/proxy/nginx.conf /etc/nginx/nginx.conf

# ------------------------------------------------------------------
# 5. Supervisord configuration
# ------------------------------------------------------------------
# Create a minimal supervisord.conf that will launch the four
# services from the same container.
RUN mkdir -p /etc/supervisor/conf.d && \
    cat > /etc/supervisor/conf.d/supervisord.conf <<EOF
[supervisord]
nodaemon=true

[program:redis]
command=/usr/bin/redis-server --port ${REDIS_PORT}
autostart=true
autorestart=true
user=root

[program:node]
command=npm run start
autostart=true
autorestart=true
user=root

[program:nginx]
command=/usr/sbin/nginx -g 'daemon off;'
autostart=true
autorestart=true
user=root
EOF

# ------------------------------------------------------------------
# 6. Expose the ports
# ------------------------------------------------------------------
EXPOSE ${REDIS_PORT} ${NGX_PORT}

# 7. Default command – start supervisord
CMD ["supervisord", "-c", "/etc/supervisor/conf.d/supervisord.conf"]
