无法在 Windows 10 上通过 gradle 构建 docker 镜像

Question

我是Docker的新手，使用gradle-docker-plugin从gradle脚本构建映像时遇到问题：

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:Learning1myprojectwebappbuild'.
Using Dockerfile 'D:Learning1myprojectwebappbuildDockerfile'
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。有人可以指出我的方向，可能出了什么问题。任何想法。

Answer 1

该插件不支持Windows。它假设你运行在Linux系统上，因为这是Docker引擎所需要的。Docker for Windows使用Hyper-V虚拟化(以前它依赖于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VM。我更喜欢跳过 Docker for Windows;相反，我使用合适的Linux来宾运行VirtualBox，然后按照该来宾内部Docker引擎的安装说明进行操作。然后，除了该来宾中的docker之外，还可以安装 gradle 和所需的任何其他开发工具。

Answer 2

您运行的是不支持Windows的旧版本的junixsocket。您需要升级到更高版本。

尝试将 junixsocket 依赖项更改为

<dependency>
  <groupId>com.kohlschutter.junixsocket</groupId>
  <artifactId>junixsocket-core</artifactId>
  <version>2.5.2</version>
  <type>pom</type>
</dependency>

PS：在原生通用的依赖配置中还有另一个错误：<type>pom</type>只应为 junixsocket-core 指定，这是一个 POM 类型的工件，包括 junixsocket-common 和 junixsocket-native-common ，它们都是 jar 类型的工件。因此，只需删除该声明，因为junixsocket-core就是您应该需要的。
