View source for Configurazione di una macchina con Puppet Masterless

* Installare puppet
 apt-get install wget lsb-release && \
 wget -O /tmp/puppet6-release-$(lsb_release -c | cut -f 2).deb https://apt.puppetlabs.com/puppet6-release-$(lsb_release -c | cut -f 2).deb && \
 sudo dpkg -i /tmp/puppet6-release-$(lsb_release -c | cut -f 2).deb && \
 apt-get update && \
 apt-get install puppet-agent

* Disabilitare il servizio:
 systemctl disable puppet.service

* Aggiungere il PATH:
 echo 'PATH="${PATH}":/opt/puppetlabs/bin' >> ~/.bash_profile
 bash ~/.bash_profile
 which puppet

 /opt/puppetlabs/bin/puppet


* Creare un modulo di test:
<pre>
cd /etc/puppetlabs/code/environments/production
mkdir -p ./modules/foo/files/
echo "hello world" > ./modules/foo/files/hello
mkdir -p ./modules/foo/manifests/
touch ./modules/foo/manifests/init.pp
mkdir -p ./manifests/
echo "include foo" > ./manifests/site.pp
cat > ./modules/foo/manifests/init.pp <<EOFile
class foo {
  file { "/tmp/hello":
    ensure => file,
    source => "puppet:///modules/foo/hello",
  }
}
EOFile
</pre>

* Testare:
 puppet apply --test --modulepath ./modules ./manifests/site.pp

* Verificare se il file è stato creato:
 cat /tmp/hello 

 hello world

* Ora si possono creare i moduli necessari e dichiararli in site.pp
* L'applicazione viene fatta one shot con
 puppet apply --test /etc/puppetlabs/code/environments/production/manifests/site.pp

* O per comodità:
 alias papply='puppet apply --test /etc/puppetlabs/code/environments/production/manifests/site.pp $@'

 papply
