# Workflow PocketBase Frontend — Dockerfile
|
||
|
|
#
|
||
|
|
# Multi-stage build for a small production image:
|
||
|
|
# - deps: install everything
|
||
|
|
# - builder: compile the Next.js app (writes standalone output)
|
||
|
|
# - runner: copy the standalone build + public assets + .next/static
|
||
|
|
# onto the alpine image
|
||
|
|
#
|
||
|
|
# Image runs as non-root user `nextjs` on port 3000.
|
||
|
|
#
|
||
|
|
# Build context: project root (where package.json lives).
|
||
|
|
# Example:
|
||
|
|
# docker build -t workflow-frontend .
|
||
|
|
# docker run --rm -p 3000:3000 \
|
||
|
|
# -e NEXT_PUBLIC_BASE_URL=https://workflow.example.co.za \
|

# -e PB_URL=https://pb.agent.apphub.co.za \
