Puppet Client
The Puppet Agent updates the configuration on the node. It automatically runs regulary, for configuration details check the configuration guide.
Manually Retrieve Node Information From Puppet Server
To manually check the node information on the Puppet server for given host, do
FQDN=$(hostname --fqdn)
curl \
--cacert /etc/puppetlabs/puppet/ssl/certs/ca.pem \
--cert /etc/puppetlabs/puppet/ssl/certs/$FQDN.pem \
--key /etc/puppetlabs/puppet/ssl/private_keys/$FQDN.pem \
"https://puppet01.psi.ch:8140/puppet/v3/node/$FQDN?environment=prod&configured_en" \
| jq .
PSON
Sometimes the puppet agent emits:
Info: Unable to serialize catalog to json, retrying with pson. PSON is deprecated and will be removed in a future release
These should be fixed in the puppet code as with Puppet 8 this will fail hard.
To figure out what part of the catalog is concerned, look at /opt/puppetlabs/puppet/cache/client_data/catalog/$(hostname --fqdn).json.
Then search for \u which starts a binary (non-utf8) character in PSON in a way that is still valid JSON.
Please improve the Puppet code wherever such non-utf8 strings are used. Be aware that not only resources, but also arguments to profiles, classes, etc. end up in the catalog.
