All checks were successful
ci/woodpecker/push/woodpecker Pipeline was successful
Fixed the mismatch between environment variables:
- docker-compose now passes PORT (what NestJS/Next.js read) instead of API_PORT
- API_PORT/WEB_PORT control host mapping, PORT controls container
Changes:
- docker-compose: Pass PORT=${API_PORT} and PORT=${WEB_PORT} to containers
- docker-compose: Dynamic port mapping on both host and container sides
- docker-compose: Traefik labels use ${API_PORT}/${WEB_PORT} variables
- docker-compose: Healthchecks use PORT env var
- Dockerfiles: Removed hardcoded port values
- Dockerfiles: Healthchecks read PORT at runtime
This allows changing ports via API_PORT/WEB_PORT environment variables
and have all components (app, healthcheck, Traefik) use the correct port.
