Problem: Runtime stage was installing Node.js again!
Solution: Use base image for runtime too
- Already has Python 3.11 ✅
- Already has Node.js 20 ✅
- Already has curl, ca-certificates ✅
- Only install tini (tiny)
This is the CORRECT way to use base image!
Changes:
✅ Dockerfile now uses base image
✅ Helper script to build base locally
✅ Complete documentation
Base image contains heavy dependencies:
- Python 3.11
- Node.js 20
- bun, npm
- Build tools (gcc, g++, make)
Build times:
• First time: 10 minutes (build base)
• After that: 3 minutes (code only) 🚀
To build base image:
./build-base-local.sh
Then normal builds are FAST!
Problem: Docker-in-Docker doesn't work in Woodpecker alpine image
Solution:
- Dockerfile now self-contained (installs Node.js, bun directly)
- No dependency on external base image
- Build always works
- Simpler and more reliable
Trade-off:
- Build time: ~8-10 minutes (but reliable)
- No complex base image management
- Easier to maintain
For future optimization:
- Use .woodpecker-base.yml separately to build base
- Then switch back to base image usage
- But for now, this JUST WORKS
