Linux+ 4.1.2: Puppet and OpenTofu

A Puppet manifest applied without a server, and an OpenTofu configuration planned, applied and destroyed with a provider that needs no cloud account.

Before you start

Work as root, so ~ is /root. The VM needs internet access to add the OpenVox and OpenTofu package repositories. The lab only checks that ~/lab.pp, ~/tofu and /tmp/puppet-lab.txt don't exist yet. le-lab reset removes those files but leaves the packages installed.

Tasks

1. Add the OpenVox 8 repository for your system (see voxpupuli.org) and install openvox-agent. Write ~/lab.pp, a manifest that manages /tmp/puppet-lab.txt with mode 0644 and the content Managed by Puppet on <OS name> (from the os.name fact). Apply it with --noop first, then for real, and ask facter for os.family.
2. Install OpenTofu from opentofu.org's packages. In ~/tofu, write a main.tf with a terraform_data resource named hello whose input is hello from OpenTofu, and an output msg with its output. Run tofu init, plan and apply, look at the state, and then destroy it.

Hints

• The release package openvox8-release-el-10.noarch.rpm (or openvox8-release-ubuntu24.04.deb), then openvox-agent; /opt/puppetlabs/bin/puppet apply --noop, /opt/puppetlabs/bin/facter.
• A file { '/tmp/puppet-lab.txt': ... } resource with ensure, content and mode; ${facts['os']['name']} in a double-quoted string.
• The installer script install-opentofu.sh with --install-method rpm or deb; tofu init, tofu plan, tofu apply -auto-approve, tofu state list, tofu destroy -auto-approve.
