如何使用 buildKit 的 Go 客户端
How to use buildKit's Go client
我正在尝试使用 builtKit, Docker's new image builder. I'm not using the command line interface but instead using the client. There's not much documentation on how to use this thing besides the examples 制作一个简单的图像生成器原型。
我需要 运行 从 Dockerfile 构建，但示例 build-using-dockerfile 不是很直观。最重要的是，当我 运行 带有 build-using-dockerfile -t 'test:latest' . 的示例（'.' 是包含简单 Dockerfile 的当前目录）时，程序在
上停止
[+] Building 0.0s (0/0)
并卡在那里。我如何使用 Dockerfile?
进行此构建
我猜你只是按照 these 步骤来配置和构建 build-using-dockerfile，你还需要配置和安装 buildkitd 守护进程。
这就是我所做的并且有效。
- 克隆 buildkit 项目
git clone https://github.com/moby/buildkit
- 配置并安装
buildkitd 和 buildctl，如前所述 here。
- 确保在后台启动
buildkitd 守护程序。 buildkitd --debug --root /var/lib/buildkit &
- 现在按照 here.
配置和安装 build-using-dockerfile
- 然后我构建我的自定义 docker 图像，这是我得到的输出
$ build-using-dockerfile -t testimage:v1 .

In-short build-using-dockerfile 在构建图像时使用 buildkitd，我猜你的情况缺少它。
希望这对您有所帮助，请告诉我。
我正在尝试使用 builtKit, Docker's new image builder. I'm not using the command line interface but instead using the client. There's not much documentation on how to use this thing besides the examples 制作一个简单的图像生成器原型。
我需要 运行 从 Dockerfile 构建，但示例 build-using-dockerfile 不是很直观。最重要的是，当我 运行 带有 build-using-dockerfile -t 'test:latest' . 的示例（'.' 是包含简单 Dockerfile 的当前目录）时，程序在

并卡在那里。我如何使用 Dockerfile?
我猜你只是按照 these 步骤来配置和构建 build-using-dockerfile，你还需要配置和安装 buildkitd 守护进程。
这就是我所做的并且有效。
- 克隆 buildkit 项目
git clone https://github.com/moby/buildkit - 配置并安装
buildkitd和buildctl，如前所述 here。 - 确保在后台启动
buildkitd守护程序。buildkitd --debug --root /var/lib/buildkit & - 现在按照 here. 配置和安装
- 然后我构建我的自定义 docker 图像，这是我得到的输出
