Question

我正在尝试通过Puppet将Ubuntu 18.04实例配置为Kubernetes主节点。为了在Ubuntu 18.04服务器上安装kublet，kubeadm和kubectl软件包，我在Puppet主服务器上定义了一个清单，我试图在其中通过Puppet的apt模块添加Kubernetes存储库。清单的相关块如下：

include apt

class kubernetes {
    file { '/opt/apt-key.gpg':
        source => [
            "https://packages.cloud.google.com/apt/doc/apt-key.gpg"
        ]
    }

    apt::key { 'kubernetes-repository':
        id => '54A647F9048D5688D7DA2ABE6A030B21BA07F4FB',
        source => 'https://packages.cloud.google.com/apt/doc/apt-key.gpg',
    }

    apt::source { 'kubernetes':
        comment => 'This is the kubernetes repository',
        location => 'http://apt.kubernetes.io/',
        repos => 'kubernetes-xenial main',
        key => {
            'id' => '54A647F9048D5688D7DA2ABE6A030B21BA07F4FB',
        },
        include => {
            'deb' => true,
        },
    }

    package { 'kubelet':
        ensure => installed,
    }

    package { 'kubeadm':
        ensure => installed,
    }

    package { 'kubectl':
        ensure => installed,
    }
}

node 'buildserver.mycompany.com' {
    include kubernetes
}

在Ubuntu 18.04服务器上，我执行以下操作以应用清单：

sudo puppet agent -t

我得到以下输出：

事实证明apt :: source正在创建预期的/etc/apt/sources.list.d/kubernetes.list文件，但是此文件中存储库的条目已添加了不需要的“仿生”存储库。文件中的条目如下所示：

deb http://apt.kubernetes.io/ bionic kubernetes-xenial main

但是我期望它看起来像这样：

deb http://apt.kubernetes.io/ kubernetes-xenial main

如何防止该“仿生”存储库进入生成的文件？

Answer 1

事实证明，该模块完全按照预期的方式运行。在apt :: source中传递'release'值的空字符串解决了我的问题。生成/etc/apt/sources.list.d/kubernetes.list文件（source.list.epp）的模板在提供的存储库列表之前为提供的“ release”值添加前缀。在Ubuntu 18.04上，当未提供“发布”值时，它似乎解析为“仿生”，这就是它最终在文件中的方式。现在我的清单是这样的：

apt::source { 'kubernetes':
    comment => 'This is the kubernetes repository',
    location => 'http://apt.kubernetes.io/',
    release => '',
    repos => 'kubernetes-xenial main',
    key => {
        'id' => '54A647F9048D5688D7DA2ABE6A030B21BA07F4FB',
    },
    include => {
        'deb' => true,
    },
}
