Then create the file puppet.conf in /etc/puppet/ or /etc/puppetlabs/puppet/ (the path depends on the version of puppet) with this content (replace 'cld-rbt-test-03' with your hostname):
# This file can be used to override the default puppet settings. # See the following links for more details on what settings are available: # - https://puppet.com/docs/puppet/latest/config_important_settings.html # - https://puppet.com/docs/puppet/latest/config_about_settings.html # - https://puppet.com/docs/puppet/latest/config_file_main.html # - https://puppet.com/docs/puppet/latest/configuration.html [agent] server=cld-config.cloud.pd.infn.it environment=production ca_server=cld-config.cloud.pd.infn.it certname=cld-rbt-test-03.cloud.pd.infn.it |
Run puppet:

Exiting now because the waitforcert setting is set to 0. |
In case of errors (because the host was already in puppet) see
[root@cld-config files]# puppetserver ca clean --certname cld-rb-test-03.cloud.pd.infn.it |

On cld-config:
[
root@cld-config modules]# puppetserver ca sign --all Successfully signed certificate request for cld-rbt-test-03.cloud.pd.infn.it [root@cld-config modules]# |
Run again puppet on the host:
[root@cld-rbt-test-03 ~]# puppet agent -t

The host should now appear on foreman.
Move it to the proper host group (e.g. hosts_all)
Enable and start puppet on the host:
[root@cld-rbt-test-03 ~]# systemctl start puppet [root@cld-rbt-test-03 ~]# systemctl enable puppet Created symlink /etc/systemd/system/multi-user.target.wants/puppet.service → /usr/lib/systemd/system/puppet.service. [root@cld-rbt-test-03 ~]# |
