# 阶段一：Chef - Cargo 依赖缓存层
# ============================================================
FROM rust:1.93-bookworm AS chef
RUN cargo install cargo-chef
WORKDIR /app

# ============================================================
# 阶段二：Planner - 生成依赖配方
# ============================================================
FROM chef AS planner
COPY Cargo.toml Cargo.lock ./
COPY crates/ crates/
RUN cargo chef prepare --recipe-path recipe.json

# ============================================================
# 阶段三：Builder - 编译依赖，然后编译源码
# ============================================================
FROM chef AS builder

# 复制并预构建依赖（此层会被缓存）
COPY --from=planner /app/recipe.json recipe.json
RUN cargo chef cook --release --recipe-path recipe.json

# 复制源码并构建
COPY Cargo.toml Cargo.lock ./
COPY crates/ crates/
RUN cargo build --release --bin rustcloud-api --bin migrate
