这是如何使用 GitHub Action 构建和将 docker 图像推到容器注册器@.的简单示例

先决条件

• 您想要构建和推动的工程 docker 文件已存在@ . @
• 此工程有一个 GitHub 仓库@. @%
• 存在一个容器登记器,可以将图像推到.
• 一个 docker 注册@' @%s 用户名和密码 @ (_ in GuitHub secrets @)}

对于这个项目,我开始的是基本的 .NET Core ASP.Net 项目和由 Rider}. 创建的默认 Dockerfile

嵌入文件

此 Docker 文件是一个多Q\ -\ 阶梯构建项目, 然后将输出复制到运行时的图像@ MS K1\

用于此 proect {,} , 当我使用 TailwindCS} ,}\ \ {我还需要安装 NOde. 并运行 LadywindCSS 构建命令@.}

# Install Node.js v20.x
RUN apt-get update && apt-get install -y curl \
    && curl -fsSL https://deb.nodesource.com/setup_20.x -o nodesource_setup.sh \
    && bash nodesource_setup.sh \
    && apt-get install -y nodejs \
    && rm -f nodesource_setup.sh \
    && rm -rf /var/lib/apt/lists/*

这将下载在写入@ ) @ 版本的诺德.}(note @ MS K2}) 时的最新 {(} 并安装到构建图像中\ .}

这个网站的 GitHub Action 是一个简单的构建和推动动作, https @://github}.comQ}/scottgal/}最普通的网路 /BloboMS K5main{/.GithubMS7workflows@/docker}-image}MS10yml

此动作检查了 Docker HUBZ , @ 设置 Docker Buildingx\ MS K2}缓存的仓库@ , 构建并标记 Ducker 图像@ MPK4}, 然后将图像按到 Decker Hub+.{
