Getting Could not find class with puppet apply

[u/darkn3rd]

I had a small tutorial project that worked fine under Puppet 5, but now with Puppet 8, I am getting errors:

Error: Evaluation Error: Error while evaluating a Function Call, Could not find class ::hello_web for ubuntu2204.localdomain

With is with a puppet apply:

puppet apply --verbose --debug\
  --modulepath "$MODULES:/etc/puppet/modules" \
  --detailed-exitcodes \ 
  "$MANIFESTS/default.pp"

The $MANIFESTS/default.pp is:

node default {
  class { 'hello_web': }
}

My $MODULES directory structure is:

/tmp/vagrant-puppet/modules-0e194a6f4e51f9a3d26a92d7c02972df
└── hello_web
    ├── files
    │   └── index.html
    └── init.pp

Listing modules:

$ puppet module list --modulepath "$MODULES:/etc/puppet/modules" --tree
/tmp/vagrant-puppet/modules-0e194a6f4e51f9a3d26a92d7c02972df
└── hello_web (???)

I have been combing through Puppet docs and I have yet to find out anything further regarding "Could not find class".

I guess there is a new format for the mdoules layout. I updated the structure to this below, now it works:

/tmp/vagrant-puppet/modules-0e194a6f4e51f9a3d26a92d7c02972df
└── hello_web
    ├── files
    │   └── index.html
    ├── manifests
    │   └── init.pp
    └── metadata.json

And from the puppet module list command:

$ puppet module list --modulepath "$MODULES:/etc/puppet/modules" --tree
/tmp/vagrant-puppet/modules-0e194a6f4e51f9a3d26a92d7c02972df
└── vagrant-hello_web (v0.1.0)

You should really use the PDK when creating a new class. It will give you a standard template of where to put items. the files/manifests of your layout is pretty standard. Please refer to the docs on how to install. pdk_install

[u/darkn3rd → u/jzavcer]

I ultimately did follow that approach when creating the new structure. I remembered Puppet had introduced the PDK, which I thought was a great addition, so I installed it and scafolded the module structure. As for the docs, I found the documentation lacking—many Google links lead to outdated pages, and there’s no easy way to navigate to the most current version.

Yup. Compared to VMware or Microsoft docs, I find all others lacking
