Puppetlabs apache module: setting the value for @expires_default in apache::mod::expires

[Flannon Jackson]

I'm running puppet 4.8 and I'm trying to configure the Puppetlabs-Apache module, which is v1.10.0.  According to the README apache::mod::expires has three parameters, one of which is expires_default.  (https://forge.puppet.com/puppetlabs/apache#class-apachemodexpires).  It also says that is uses expires.conf.erb to generate it's configuration and that expires_default is undef by default, and puppetlabs-apache/templates/mod/expires.conf.erb has the following template,

ExpiresActive <%= scope.function_bool2httpd([@expires_active]) %>

<%- if ! @expires_default.nil? and ! @expires_default.empty? -%>

ExpiresDefault "<%= @expires_default %>"

<%- end -%>

<%- if ! @expires_by_type.nil? and ! @expires_by_type.empty? -%>

<%- [@expires_by_type].flatten.each do |line| -%>

<%- line.map do |type, seconds| -%>

ExpiresByType <%= type %> "<%= seconds -%>"

<%- end -%>

<%- end -%>

    <%- end -%>

So I figured I could do this to set the value for ExpiresDefault in the apache config,

    class { 'apache::mod::expires' :
        expires_default => ['access', 'plus', '5184000', 'seconds',],
    }

But when I run Puppet I get a duplicate declarations error,

"Error: Evaluation Error: Error while evaluating a Resource Statement, Duplicate declaration: Apache::Mod[expires] is already declared in file /tmp/vagrant-puppet/environments/development/modules/thirdparty/apache/manifests/default_mods.pp:66; cannot redeclare at /tmp/vagrant-puppet/environments/development/modules/thirdparty/apache/manifests/mod/expires.pp:7 at /tmp/vagrant-puppet/environments/development/modules/thirdparty/apache/manifests/mod/expires.pp:7:3 on node loris.local"

So it looks like apache::mod::expires is defined in default_mods.pp and mod/expires.pp.  I'm not really sure what's going on, but I feel like I'm missing something very basic here.

Any help would be appreciated,

Thanks,

In the `apache` class there is a `default_mods` parameter as well (param https://github.com/puppetlabs/puppetlabs-apache#default_mods and code path https://github.com/puppetlabs/puppetlabs-apache/blob/28e9d41b2028f13c81b43e47c79bd28899170ccb/manifests/init.pp#L334-L345), it looks like you would want to set that to `false` or an array that does not contain `expires`. That is just from a simple reading of the description and the code, not from experience using it, though.

That was it.  Thanks very much for the reply.
