如何在拥有私有 docker 注册表服务器的同时将 docker 与 gradle 一起使用

Question

我正在尝试使用我的环境设置 https://spring.io/guides/gs/spring-boot-docker/#initial，该环境具有私有注册表服务器@

el-qa-docker.x.x.x:18445

My build.gradle 有以下相关内容：

dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:1.5.3.RELEASE")
        classpath('se.transmode.gradle:gradle-docker:1.2')
        classpath ('org.codehaus.groovy:groovy-backports-compat23:2.3.5')
    }
group = 'james'
apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'org.springframework.boot'
apply plugin: 'docker'
task buildDocker(type: Docker, dependsOn: build) {
  push = true
  applicationName = jar.baseName
  dockerfile = file('src/main/docker/Dockerfile')
  doFirst {
    copy {
      from jar
      into stageDir
    }
  }
}

当我跑步时：$gradle build buildDock

我得到构建失败，与：

    $ gradle build buildDock
    :compileJava UP-TO-DATE
    :processResources UP-TO-DATE
    :classes UP-TO-DATE
    :findMainClass
    :jar
    :bootRepackage
    :assemble
    :compileTestJava UP-TO-DATE
    :processTestResources UP-TO-DATE
    :testClasses UP-TO-DATE
    :test UP-TO-DATE
    :check UP-TO-DATE
    :build
    :buildDocker FAILED
    FAILURE: Build failed with an exception.
    * What went wrong:
    Execution failed for task ':buildDocker'.
    > Docker execution failed
      Command line [docker build -t skahmed/gs-spring-boot-docker:latest /Users/skahmed/devops/TOOLS/DOCKER/gs-spring-boot-docker/initial/build/docker] returned:

    * Try:
    Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
BUILD FAILED

任何想法，关于我在哪里指定可以与 Gradle 一起使用的 docker 内部注册表。

我试过了：

docker {
  useApi true
  hostUrl 'el-qa-docker.x.x.x:18445'
  apiUsername 'james'
}

由 https://github.com/Transmode/gradle-docker 提供

但这给出了一个不同的错误：

 $ gradle build buildDock
:compileJava UP-TO-DATE
:processResources UP-TO-DATE
:classes UP-TO-DATE
:findMainClass
:jar
:bootRepackage
:assemble
:compileTestJava UP-TO-DATE
:processTestResources UP-TO-DATE
:testClasses UP-TO-DATE
:test UP-TO-DATE
:check UP-TO-DATE
:build
:buildDocker FAILED
FAILURE: Build failed with an exception.
* What went wrong:

> Port is invalid: -1
* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
BUILD FAILED
Total time: 1.389 secs

我试过：build.gradle

docker {
   //useApi true
   hostUrl 'el2-dt-docker.uscis.dhs.gov:18445'
   apiUsername 'skahmed'
}

和

task buildDocker(type: Docker, dependsOn: build) {
  push = true
  applicationName = jar.baseName
  //applicationName = 'el2-dt-docker.uscis.dhs.gov:18445/skahmed/gs-spring-boot-docker'
  //applicationName = 'gs-spring-boot-docker'
  dockerfile = file('src/main/docker/Dockerfile')
  doFirst {
    copy {
      from jar
      into stageDir
    }
  }
}

但得到：

:buildDocker FAILED
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':buildDocker'.
> Docker execution failed
  Command line [docker push skahmed/gs-spring-boot-docker:latest] returned:

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
BUILD FAILED

Answer 1

您可以将私有 Docker 注册表指定为 Docker 映像名称的一部分，例如：

el-qa-docker.x.x.x:18445/skahmed/gs-spring-boot-docker

请确保您的 Docker 守护程序知道私有注册表。
