Swift 容器插件

使用 Swift Package Manager 发布容器镜像。

了解 Swift 容器插件并查看它的实际应用

概述

Swift 容器插件提供了一个 Swift Package Manager 命令插件和实用程序，以便轻松构建用 Swift 编写的服务器的容器镜像。

容器镜像是当今打包云软件的标准方式。 将服务器打包成容器镜像后，您可以将其部署在任何基于容器的公共或私有云服务上，或者使用桌面容器运行时在本地运行它。

设置项目后，您可以使用该插件一步构建和发布容器镜像

% swift package --swift-sdk x86_64-swift-linux-musl \
        build-container-image --repository registry.example.com/myservice
...

然后，您可以使用容器运行时（例如 podman）来运行该镜像

% podman run -p 8080:8080 registry.example.com/myservice@sha256:a3f75d0932d052dd9d448a1c9040b16f9f2c2ed9190317147dee95a218faf1df

入门指南

Swift 容器插件需要 Swift 6.0，并在 macOS 和 Linux 上运行。 它不需要安装本地容器运行时即可构建镜像。
