NEXT_PUBLIC_API_URL is baked into the frontend bundle at build time — always pass it explicitly.

# Backend
docker build -t registry.gabrielkaszewski.dev/k-tv-backend:latest ./k-tv-backend

# Frontend — NEXT_PUBLIC_API_URL required
docker build \
  --build-arg NEXT_PUBLIC_API_URL=https://tv-api.gabrielkaszewski.dev/api/v1 \
  -t registry.gabrielkaszewski.dev/k-tv-frontend:latest \
  ./k-tv-frontend

Push

docker push registry.gabrielkaszewski.dev/k-tv-backend:latest
docker push registry.gabrielkaszewski.dev/k-tv-frontend:latest

Build + push (one-liner)
