It is only valid on a Puppet master server; in Puppet apply, the compiler doesn’t add certificate extensions to
When a node requests a certificate, it can ask the CA to include some additional, permanent metadata in that cert. (Puppet agent uses the
csr_attributes.yaml file to decide what extensions to request.)
If the CA signs a certificate with extensions included, those extensions are available as trusted facts in the top-scope
$trusted variable. Your manifests or node classifier can then use those trusted facts to decide which nodes can receive which configurations.
By default, the Puppet-specific registered OIDs appear as keys with convenient short names in the
$trusted[extensions] hash, and any other OIDs appear as raw numerical IDs. You can use the
custom_trusted_oid_mapping.yaml file to map other OIDs to short names, which will replace the numerical OIDs in
For more info, see:
Mapping OIDs in this file only affects the keys in the
$trusted[extensions] hash. It does not affect:
csr_attributes.yamlfile — anything but Puppet-specific registered extensions must still be numerical OIDs.
puppet cert print— mapped extensions will still be displayed as numerical OIDs. (Improving cert display is planned as PUP-4617.)
The OID mapping file is located at
$confdir/custom_trusted_oid_mapping.yaml by default. Its location is configurable with the
The location of the
confdir depends on your OS. See the confdir documentation for details.
