Question

我正在使用https://github.com/bmuschko/gradle-docker-plugin从gradle连接到docker。我有以下任务在Windows上创建容器：

task "docker-container-create"(type: DockerCreateContainer) {
    description = "Create Docker container"
    group "${dockerGroup}-container"

    ext {
        dockerTag = project.dockerTag 
    }

    targetImageId { "${dockerRepository}:${project.dockerTag}" as String }
    delegate.containerName = containerName

    portBindings = ["80:${project.dockerExposedPort}"]

    env = ["GRAILS_ENV=development"]
    cmd = ["--app.dockerContainerName=${containerName}"]

    if(!new File("${project.projectDir}/data").exists()) new File("${project.projectDir}/data").mkdirs()

    binds [
        ("${project.projectDir}/data" as String):'/app/data',
        ("${project.projectDir}/src/main/config/" as String):'/app/config',
    ]
}

但是这失败并出现以下错误：

{"message":"invalid volume specification: '/host_mnt/c/Users/**/parts/data:rw'"}

我正在运行Docker版本17.12.0-ce-win47 (15139)-stable

显然，应按照此版本的发行说明中所述的//C/<folder>格式定义Windows挂载点：

Fix Mount compatibility when mounting drives with `-v //c/...`, now mounted in /host_mnt/c in the LinuxKit VM. Fixes [docker/for-win#1509](https://github.com/docker/for-win/issues/1509), [docker/for-win#1516](https://github.com/docker/for-win/issues/1516),

我在gradle构建文件中创建了一个小帮助程序实用程序：

    def volumes = {volumes -> volumes.collectEntries{k,v ->
        if(k.contains('\\')){
            k = "//${k.replaceAll('\\\\','/')}"
            k = k.replaceAll(':','')
        }
        [(k):v]
    }}

所以配置现在是：

task "docker-container-create"(type: DockerCreateContainer) {
    description = "Create Docker container"
    group "${dockerGroup}-container"

    ext {
        dockerTag = project.dockerTag 
    }

    targetImageId { "${dockerRepository}:${project.dockerTag}" as String }
    delegate.containerName = containerName

    portBindings = ["80:${project.dockerExposedPort}"]

    env = ["GRAILS_ENV=development"]
    cmd = ["--app.dockerContainerName=${containerName}"]

    if(!new File("${project.projectDir}/data").exists()) new File("${project.projectDir}/data").mkdirs()

    def volumes = {volumes -> volumes.collectEntries{k,v ->
        if(k.contains('\\')){
            k = "//${k.replaceAll('\\\\','/')}"
            k = k.replaceAll(':','')
        }
        [(k):v]
    }}

    binds = volumes([
        ("${project.projectDir}/data" as String):'/app/data',
        ("${project.projectDir}/src/main/config/" as String):'/app/config',
    ])
}

这很有效。
