Reverse proxy image for WebProtege. Fronts the UI server, API gateway, Keycloak, and Kibana on a single HTTP endpoint.

• Dockerfile — extends the official nginx:latest image
• nginx.conf — server config copied to /etc/nginx/conf.d/default.conf

The config uses lazy DNS (resolver 127.0.0.11 + proxy_pass $variable) so the proxy starts independently of its upstreams and resolves them on demand — required for clean cold starts in Docker Compose, where upstream containers may not exist yet when nginx boots.

• Docker

docker build -t protegeproject/webprotege-nginx:$(cat VERSION) .

The image version is tracked in the VERSION file at the repo root and bumped automatically after each release by the CI workflow.

See the webprotege-deploy README.
