docker - 如何使用 buildKit 的 Go 客户端

Question

我正在尝试使用 builtKit 制作一个简单的图像生成器的原型(prototype)。 , Docker 的新镜像生成器。我没有使用命令行界面，而是使用 client .除了 examples 之外，没有太多关于如何使用这个东西的文档。 .

我需要从 Dockerfile 运行构建但是示例 build-using-dockerfile不是很直观。最重要的是，当我使用 build-using-dockerfile -t 'test:latest' . 运行示例时( '.' 是当前目录，其中包含一个简单的 Dockerfile )程序停止

[+] Building 0.0s (0/0)

并且卡在那里。如何使用 Dockerfile 进行此构建?

Answer 1

我猜你只是关注了these配置和构建步骤build-using-dockerfile ，还需要配置安装buildkitd守护进程。

这就是我所做的，并且奏效了。

克隆 buildkit 项目 git clone https://github.com/moby/buildkit

配置安装buildkitd和 buildctl如前所述here .

确保您开始 buildkitd后台守护进程。 buildkitd --debug --root /var/lib/buildkit &

现在配置和安装build-using-dockerfile如前所述here .

然后我构建了我的自定义 docker 镜像，这是我得到的输出

$ build-using-dockerfile -t testimage:v1 .
