Puppet apt:：source在Ubuntu 18.04上添加不需要的“仿生”存储库条目

我试图通过Puppet将Ubuntu 18.04实例配置为Kubernetes主节点。为了在Ubuntu18.04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，我试图通过Puppet的apt模块在其中添加Kubernetes存储库。清单的相关区块如下所示：

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，但该文件中的存储库条目添加了一个不需要的“仿生”存储库。文件中的条目如下所示：

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

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

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,
    },
}

 [<%- if ($opt_architecture) {%>arch=<%= $opt_architecture %><% } %><%if ($opt_architecture and $allow_unsigned) {%> <% }%><% if ($allow_unsigned) {%>trusted=yes<% } %>] <%- } %> <%= $location %> <%= $release %> <%= $repos %>

但我希望它看起来像这样：

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

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

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,
    },
}

 [<%- if ($opt_architecture) {%>arch=<%= $opt_architecture %><% } %><%if ($opt_architecture and $allow_unsigned) {%> <% }%><% if ($allow_unsigned) {%>trusted=yes<% } %>] <%- } %> <%= $location %> <%= $release %> <%= $repos %>

我该怎么做才能防止这个“仿生”存储库将其放入结果文件中？

结果表明，模块正在做它应该做的事情。在apt:：source中为“release”值传入空字符串修复了我的问题。生成/etc/apt/sources.list.d/kubernetes.list文件的模板在提供的存储库列表之前加上提供的“release”值的前缀。在Ubuntu18.04上，当没有提供“release”值时，它似乎解析为“bionic”，这就是它在文件中的结尾。现在我的清单如下所示：

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

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

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,
    },
}

 [<%- if ($opt_architecture) {%>arch=<%= $opt_architecture %><% } %><%if ($opt_architecture and $allow_unsigned) {%> <% }%><% if ($allow_unsigned) {%>trusted=yes<% } %>] <%- } %> <%= $location %> <%= $release %> <%= $repos %>

根据和，您可以使用apt:：source。我怀疑罪魁祸首是您的include apt，它将以某种方式隐式地配置您的服务器，您不需要它，因为您正在使用两种已定义的资源类型。谢谢！查看source.list.epp文件，第5行中使用的“release”值似乎是我的问题的关键。我相信在我的Ubuntu18.04服务器上，“发布版”是解决“仿生”问题的关键。为了解决这个问题，我在Puppet主服务器的清单中提供了一个设置为空字符串的“release”值。这就成功了！奇怪的是，我认为我已经在模板中运行了release变量，并验证了它不是这样。然而，我错了，这是你的问题。当然，你的修复将工作给予。
