Puppet Client
The Puppet Agent updates the configuration on the node. It automatically runs regularly, for configuration details check the configuration guide.
The puppet client can be manually triggered/run by calling following command on the client:
puppet agent -t
To only check what the client would actually do, without actually changing the systems configuration/files/etc. you can use the --noop option:
puppet agent -t --noop
To instruct the puppet client to use a specific puppet environment use:
puppet agent -t --environment my_environment
The client will keep this environment until
- either the puppet environment is removed from the server (i.e. the client will do a fallback to the default environment)
- you manually change the environment again
Configuration
Attach Node to Different Puppet Server
For testing purpose you might want to change the Puppet server to which a test node is attached to. To do so do, change the server in the [main] section of /etc/puppetlabs/puppet/puppet.conf accordingly.
Then delete the current host and CA certificate and the CRL:
rm -f /etc/puppetlabs/puppet/ssl/certs/*
rm -f /etc/puppetlabs/puppet/ssl/crl.pem
Finally run the puppet agent again.
