Puppet评估错误：评估资源语句时出错，无法找到声明的类

Question

I'm trying to deploy an application called Bag-Of-Holding via Puppet using the instruction as posted on github - https://github.com/ribeiroit/boh-puppet

I run the command: sudo puppet apply /etc/puppet/manifests/site.pp and I get the error below:

Error: Evaluation Error: Error while evaluating a Resource Statement, Could not find declared class boh at /etc/puppet/manifests/site.pp:2:2 on node lab1-hp-elitebook-8570p

It appears the puppet is having hard time finding the class boh which is already in the manifest folder

This is my directory tree:

/etc/puppet
├── code
├── manifests
└── modules
    └── boh-puppet
        ├── manifests
        └── templates

my site.pp file is located in /etc/puppet/manifests and it looks like this:

node 'lab1-hp-elitebook-8570p' {
  class { 'boh':
    python_version   => 3,
    environment      => 'dev',
    language         => 'en',
    debug            => 'True',
    create_superuser => 'true',
    pkg_checksum     => '86b0164f7fd6c5e4aa43c8f056f08cea'
  }
}

And init.pp file has the class {boh } and that's located at: /etc/puppet/modules/boh-puppet/manifests

Any ideas how to fix this?

Answer 1

Puppet requires certain namespace restrictions and conventions with module directory structure and class names when autoloading. In this case, your problem can be solved most simply and cleanly to follow normal conventions by renaming your module directory of boh-puppet to simply boh . That will fix your issue.

Consult the documentation here for more information: https://puppet.com/docs/puppet/4.10/lang_namespaces.html

Since you are using puppet apply with absolute paths, you will also need to supply the path to your modules by modifying the command to: sudo puppet apply --modulepath=/etc/puppet/modules /etc/puppet/manifests/site.pp .

Answer 2

You are not calling the module name properly. This should work:

node 'lab1-hp-elitebook-8570p' {
        class { 'boh-puppet':
        python_version => 3,
        environment => 'dev',
        language => 'en',
        debug => 'True',
        create_superuser => 'true',
        pkg_checksum => '86b0164f7fd6c5e4aa43c8f056f08cea'
        }
}

or the fqn this:

node 'lab1-hp-elitebook-8570p' {
        class { '::boh-puppet':
        python_version => 3,
        environment => 'dev',
        language => 'en',
        debug => 'True',
        create_superuser => 'true',
        pkg_checksum => '86b0164f7fd6c5e4aa43c8f056f08cea'
        }
}
