不能从与jenkins服务相同的文件中提供scala/sbt

Question

我对木偶很陌生，所以如果这是个愚蠢的问题，请原谅我。我找不到类似的问题。

下面是我要做的事情:我使用迷航器和使用詹金斯-木偶模块的傀儡提供一个jenkins环境。到目前一切尚好。我可以创建一个主程序，我可以使用群集插件轻松地使用模块中的jenkins::slave包创建一个从服务器

class { 'jenkins::slave':
    masterurl => 'http://jenkins-master-url:8080',
    version => "2.0",
    slave_mode => "exclusive",
    labels => "scala sbt"
}

但是，我需要scala和sbt在这个奴隶上，这就是我遇到问题的地方。安装工程良好使用

package { "openjdk": name => "openjdk-7-jre" }
## SBT
wget::fetch { "download sbt":
    source => "https://dl.bintray.com/sbt/debian/sbt-0.13.2.deb",
    destination => "/tmp/sbt-0.13.2.deb",
    cache_dir => "/vagrant/cache/"
}
package { "sbt":
    provider => "dpkg",
    source => "/tmp/sbt-0.13.2.deb",
    require => [ File["/tmp/sbt-0.13.2.deb"], Package["scala"] ]
}

file_line { "sbt options":
    path => "/etc/environment",
    line => "SBT_OPTS=\"-Xms40M -Xmx2G -Xss2M -XX:+CMSClassUnloadingEnabled -XX:MaxPermSize=1G -Djavax.net.ssl.trustStore=cacerts -Djavax.net.ssl.trustStorePassword=********\"",
    match => "^SBT_OPTS"
}

## SCALA
wget::fetch { "download scala":
    source => "http://www.scala-lang.org/files/archive/scala-2.10.3.deb",
    destination => "/tmp/scala-2.10.3.deb",
    cache_dir => "/vagrant/cache/"
}

package { "libjansi-java": }
package { "scala":
    provider => "dpkg",
    source => "/tmp/scala-2.10.3.deb",
    require => [ File["/tmp/scala-2.10.3.deb"], Package["openjdk"], Package["libjansi-java"] ]
}'

但是，当我尝试从一个傀儡脚本运行这些命令时，它失败了，它告诉我缺少一个java6依赖项(已经与jenkins服务一起安装)，并告诉我要运行apt-get -f install。当我对着机器做那件事时，它就成功了。

但是，当我使用两个脚本(首先安装服务，然后不运行apt-get -f install)执行scala/sbt操作时，它就成功了。

基本上，我的问题是，这个错误意味着什么，从某个脚本中运行它在某种程度上是可能的吗？为了维护性和保持代码的整洁，我希望这样做。

我的这两个脚本的迷走片文件看起来像

config.vm.define "linux-slave" do |node|
    node.vm.box = "debian/jessie64"
    node.vm.hostname = "jenkins-slave.box"
    node.vm.network :private_network, ip: "172.28.128.12"

    node.vm.provider :virtualbox do |v|
        v.memory = 2048
        v.cpus = 2
    end

    node.vm.provision :shell, inline: "apt-get update && apt-get install -y puppet vim"
    node.vm.provision :puppet do |puppet|
        puppet.manifests_path = "jenkins-slave"
        puppet.module_path = ".modules"
        puppet.manifest_file = "default.pp"
        puppet.options = "--parser future"
    end

    node.vm.provision :puppet do |puppet|
        puppet.manifests_path = "jenkins-slave"
        puppet.module_path = ".modules"
        puppet.manifest_file = "sbt-scala.pp"
        puppet.options = "--parser future"
    end

end

我想去掉第二个node.vm.provision :puppet do |puppet| ... end部分。

这是木偶执行命令的顺序吗？我能用某种方式强迫你吗？

周围有木偶大师知道吗？

Answer 1

安装告诉您需要安装Java才能将scala安装为依赖于1.6或更高版本

安装Java有许多不同的方法，但我建议使用木偶模块

Answer 2

结果发现需求是不正确的，这里需要JDK。

package { "scala":
    provider => "dpkg",
    source => "/tmp/scala-2.10.3.deb",
    require => [ File["/tmp/scala-2.10.3.deb"], Package["openjdk"],    Package["libjansi-java"] ]
}'

最后，解决了需要文件的问题(如@Frédéric所述)

exec { "enable-jenkins-slave":
    command => "/bin/systemctl enable jenkins-slave",
    require => File['/etc/init.d/jenkins-slave'],
    before => Service["jenkins-slave"],
}
