java - 无法在 Windows 10 上通过 gradle 构建 docker 镜像

Question

我是 Docker 新手，在使用 gradle-docker-plugin 从 gradle 脚本构建镜像时遇到问题:

task dockerBuildImage(type: DockerBuildImage, dependsOn: [dockerCreateDockerfile, assemble]) {
    tag = "my_tag_here"
    dockerFile = dockerCreateDockerfile.destFile
    inputDir = dockerCreateDockerfile.destFile.parentFile
}

比我得到这样的堆栈跟踪:

Building image using context 'D:\Learning\1\myproject\webapp\build'.
Using Dockerfile 'D:\Learning\1\myproject\webapp\build\Dockerfile'
Using tag 'localhost:5000/test/myproject-webapp:1.0.0-20170318135307' for image.

:webapp:dockerBuildImage FAILED

如果我直接运行“docker build”命令 - 一切正常。 有人可以指出我可能出错的方向吗？有任何想法吗。

Answer 1

该插件不支持Windows。它假设您在 Linux 系统上运行，因为这是 Docker 引擎所需要的。 Docker for Windows 使用 Hyper-V 虚拟化(之前依赖 VirtualBox)。

您需要在 Linux 系统上运行此 Gradle 插件。这可能是 Windows 计算机上的虚拟机。我更喜欢跳过适用于 Windows 的 Docker；相反，我使用合适的 Linux guest 运行 VirtualBox，然后按照该 guest 内的 Docker 引擎安装说明进行操作。然后，除了该 guest 中的 docker 之外，您还可以安装 gradle 以及您需要的任何其他开发工具。
