# syntax=docker/dockerfile:1
#
# Единый multi-stage Dockerfile для всего LMS.
# Сборка идёт внутри образа (Gradle + JDK 21), поэтому на сервере
# достаточно Docker — устанавливать Java не требуется.
#
# Использование (см. docker-compose.prod.yml):
#   docker build --target web        -t lms-web .
#   docker build --target identity   -t lms-identity .

# ---------- Стадия сборки ----------
FROM eclipse-temurin:21-jdk AS build
WORKDIR /src

# Сначала копируем файлы сборки — слой кэшируется отдельно от исходников.
COPY gradlew gradlew
COPY gradle gradle
COPY settings.gradle.kts gradle.properties ./
COPY buildSrc buildSrc
RUN chmod +x gradlew

# Исходники модулей.
COPY libs libs
COPY services services
COPY web web

RUN --mount=type=cache,target=/root/.gradle \
    ./gradlew --no-daemon bootJar -x test

# ---------- Runtime-стадии (только JRE) ----------
