Modernize Docker setup: build from source, add OWL2VOWL integration #214
Conversation
- Replace WAR downloads with multi-stage builds from GitHub source - Update from Java 8 Alpine to Java 11/17 Temurin - Add Dockerfile.combined: all-in-one image with nginx reverse proxy - Add Dockerfile.owl2vowl: dedicated OWL2VOWL converter service - Add comprehensive documentation (PODMAN_SETUP.md, QUICK_START.md) - Podman and Docker compatible - Fixes broken WAR file downloads from vowl.visualdataweb.org This allows users to run WebVOWL with OWL2VOWL converter without depending on external file downloads that are no longer available.

Extra network is not necessary. compose creates one as default per compose project

newer node versions probably not work because of the old project?

what purpose do you see in keeping both variants? combined vs single one images?
If splitted owl2vowl has to be in its one repository

to specific and podman is not commonly used. It should be better done with docker as podman should work as direct replacement to docker.

This file is not needed. Everything should be done in the README itself.
| All Docker commands work with Podman. Simply replace `docker` with `podman`: | ||

| ```bash | ||
| podman build -t webvowl:combined -f Dockerfile.combined . |

Thank you for your feedback, I will stick to docker |
