Puppet+Kubernetes : Error while applying a puppet manifest to add the kubernetes repository

0 votes

I'm trying to configure an Ubuntu 18.04 using Puppet as a Kubernetes master. There's a puppet manifest on puppet master which defines the required configurations to install the kublet, kubeadm, and kubectl packages on the Ubuntu server, where i am trying to add the kubernetes repo using apt module of puppet.

sudo puppet agent -t

Here's the output.

Here's the manifest's code snippet:

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
}

The apt module, apt::source is creating the /etc/apt/sources.list.d/kubernetes.list file, but the entry for the repository in this file has an unwanted repository added to it. How can I prevent this error?

I guess there isn't an issue with the module. 

Try to pass an empty string value for the 'release' value in apt::source. This might prevent it.

The template that generates the /etc/apt/sources.list.d/kubernetes.list file (source.list.epp) prefixes the provided 'release' value prior to the provided list of repositories. 

On Ubuntu 18.04, when no 'release' value is provided it appears to resolve to 'bionic', which is how it was ending up in the file. 

Your manifest should look like this:

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 %>
