Create Docker container for Subarr #4
Description
Could you publish docker image for Subarr ?
A Dockerfile and Compose base if that helps :)
Dockerfile
# ---------- Build stage ----------
FROM node:20-alpine AS build
ARG SUBARR_VERSION=master
RUN apk add --no-cache git
WORKDIR /app
# Grab Subarr
RUN git clone --depth=1 --branch "${SUBARR_VERSION}" https://github.com/derekantrican/subarr.git /app
# Install deps at workspace root
# (npm ci if lockfile present, else npm install)
RUN if [ -f package-lock.json ]; then npm ci --no-audit --no-fund; else npm install --no-audit --no-fund; fi
# Build the React client now (so runtime won’t need to write /app/client/build)
RUN npm --workspace client run build
# Trim dev deps to keep the final copy lighter
RUN npm prune --omit=dev
# ---------- Runtime stage ----------
FROM node:20-alpine AS runtime
# add tools you want; add ffmpeg/yt-dlp only if you’ll use "Process" actions
RUN apk add --no-cache tzdata curl
ENV TZ=Europe/Paris NODE_ENV=production PORT=5000
WORKDIR /app
# Copy only what we need to run
COPY --from=build /app/package*.json /app/
COPY --from=build /app/server /app/server
COPY --from=build /app/client/build /app/client/build
# Preserve any remaining node_modules from build if present
COPY --from=build /app/node_modules /app/node_modules
# Non-root user & permissions
RUN addgroup -S app -g 10001 && adduser -S app -G app -u 10001 \
&& chown -R app:app /app
USER app
EXPOSE 5000
# IMPORTANT: start server directly (do NOT run the script that rebuilds the client)
CMD ["node", "server/index.js"]
BUILD : docker compose build --no-cache

environment:

ports:
- "5050:5000"
# NOTE: we do NOT set read_only here, because the server likely writes its SQLite DB
# into /app/server (path not documented). If you later confirm a dedicated data dir,
# we can re-enable read_only and mount just that path R/W.
