Update puppet.conf file under [main] in puppetmaster container -># vi etc/puppet/puppet.conf -> certname = master.demo.com -> Update puppet.conf file in puppetagent container -># vi etc/puppet/puppet.conf -> server = master.demo.com ->

Start puppet master in puppetmaster container -># service puppetmaster start -># service puppetmaster status ->

AUTHENTICATE PUPPET AGENT IN PUPPET MASTER

Request certification from agent -># puppet agent --test --server=<master hostname> master.demo.com --waitforcert=50 -> check for certificate request in master -># puppet cert list -> sing certification in master -># puppert cert sign <agent hostname> agent.demo.com ->
