如何从docker运行firestore模拟器并保存数据

FROM openjdk:8-jdk-alpine

# 设置工作目录
WORKDIR /usr/src/app

# 下载 Firestore 模拟器
RUN apk add --no-cache curl && \
    curl -o firestore-emulator-v1.13.1.jar https://storage.googleapis.com/firebase-preview-drop/emulator/cloud-firestore-emulator-v1.13.1.jar

# 暴露 Firestore 模拟器的默认端口
EXPOSE 8080

# 启动 Firestore 模拟器
CMD ["java", "-jar", "firestore-emulator-v1.13.1.jar", "--host=0.0.0.0", "--port=8080"]

docker build -t firestore-emulator .

docker run -d --name firestore-emulator -p 8080:8080 -v $(pwd)/firestore-data:/usr/src/app/data firestore-emulator

const admin = require('firebase-admin');
const { Firestore } = require('@google-cloud/firestore');

// 初始化 Firebase Admin SDK
admin.initializeApp({
  projectId: 'your-project-id',
});

// 获取 Firestore 实例
const firestore = new Firestore();

// 配置 Firestore 客户端以连接到模拟器
firestore.settings({
  host: 'localhost:8080',
  ssl: false,
});

// 现在你可以使用 Firestore 客户端进行操作

docker exec firestore-emulator java -jar firestore-emulator-v1.13.1.jar export /usr/src/app/data/export

docker exec firestore-emulator java -jar firestore-emulator-v1.13.1.jar import /usr/src/app/data/export
