Dockerfile

# OpenConcho web SPA — self-hosted Honcho dashboard.
#
# Multi-stage build:
#   1. node:22-alpine + pnpm builds the @openconcho/web SPA to packages/web/dist
#   2. nginx-unprivileged serves the static bundle as non-root (UID 101) on
#      port 8080 — runs cleanly under read-only filesystem + cap_drop ALL.

# ---------- Builder stage ----------
FROM node:22-alpine AS builder

RUN corepack enable \
 && corepack prepare pnpm@10.33.2 --activate
