java - Firestore 模拟器在 Docker 中运行时无法启动

问题描述

我正在运行一个基于alpine该镜像nodejs并openjdk8已安装的 docker 镜像。在我成功安装之后，我尝试使用以下命令启动 firestore 模拟器firebase-tools：npm

firebase serve --only firestore

我收到以下错误：

    ⚠  firestore: Exception in thread "main"
    ⚠  firestore: java.io.IOException: Failed to bind

我尝试设置JAVA_OPTS如下：

export JAVA_OPTS="-Djava.net.preferIPv4Stack=true -Djava.net.preferIPv4Addresses=true"

但我仍然收到类似的错误：

有没有人看到这个错误并找到了解决方案？

解决方案

解决方案很简单，尽管我必须承认没有多大意义，就是直接运行 JAR 而不是通过firebase工具启动它。

java -jar $HOME/.cache/firebase/emulators/cloud-firestore-emulator-v1.3.0.jar --host=127.0.0.1
