Docker部署dart-frog服务

参考：

dart-frog官网：https://dartfrog.vgv.dev/docs/overview

使用 'Dart Frog' 体验 Dart 服务端开发 - 简书

打包项目

按照demo新增项目后，执行：

dart_frog build

等待build后生成 build 文件夹，这个文件夹就是需要部署的内容

需要注意，由于环境问题，需要编辑一下 build/Dockerfile 文件：

# Official Dart image: https://hub.docker.com/_/dart
# Specify the Dart SDK base image version using dart:<version> (ex: dart:2.17)

FROM dart:stable AS build

# 在此处添加PUB_HOSTED_URL 和 FLUTTER_STORAGE_BASE_URL

ENV PUB_HOSTED_URL="https://pub.flutter-io.cn"
ENV FLUTTER_STORAGE_BASE_URL="https://storage.flutter-io.cn"

WORKDIR /app

# Copy Dependencies

# Install Dependencies

# Resolve app dependencies.
COPY pubspec.* ./
RUN dart pub get

# Copy app source code and AOT compile it.
COPY . .
# Ensure packages are still up-to-date if anything has changed
RUN dart pub get --offline
RUN dart compile exe bin/server.dart -o bin/server

# Build minimal serving image from AOT-compiled `/server` and required system
# libraries and configuration files stored in `/runtime/` from the build stage.
FROM scratch
COPY --from=build /runtime/ /
COPY --from=build /app/bin/server /app/bin/

# Start server.
CMD ["/app/bin/server"]

部署服务器

然后把 build/ 放到服务器

需要先查看Docker 有没有 dart 环境,如果没有就下载一下

docker pull dart:latest

在服务器下进入文件夹执行一下指令，构建项目（Custom Dockerfile）

docker build . -t dart-frog-app

如果没有修改Dockerfile文件，编译的时候会报错
