puppet-ca - Local Puppet Certificate Authority management.
puppet ca action
This provides local management of the Puppet Certificate Authority.
You can use this subcommand to sign outstanding certificate requests, list and manage local certificates, and inspect the state of the CA.
Note that any setting that's valid in the configuration
file is also a valid long argument, although it may or may not be
relevant to the present action. For example,
run_mode are valid
settings, so you can specify
--server <servername>, or
--run_mode <runmode> as an argument.
See the configuration file documentation at
https://docs.puppetlabs.com/puppet/latest/reference/configuration.html for the
full list of acceptable parameters. A commented list of all
configuration options can also be generated by running puppet with
console, but other options such as
dotare sometimes available.
destroy - Destroy named certificate or pending certificate request.:
puppet ca destroy
Destroy named certificate or pending certificate request.
fingerprint - Print the DIGEST (defaults to the signing algorithm) fingerprint of a host's certificate.:
puppet ca fingerprint [--digest ALGORITHM]
Print the DIGEST (defaults to the signing algorithm) fingerprint of a host's certificate.
--digest ALGORITHM -
The hash algorithm to use when displaying the fingerprint
generate - Generate a certificate for a named client.:
puppet ca generate [--dns-alt-names NAMES]
Generate a certificate for a named client.
--dns-alt-names NAMES -
A comma-separated list of alternate DNS names for Puppet Server. These are extra
hostnames (in addition to its
certname) that the server is allowed to use when
serving agents. Puppet checks this setting when automatically requesting a
certificate for Puppet agent or Puppet Server, and when manually generating a
puppet cert generate.
In order to handle agent requests at a given hostname (like "puppet.example.com"), Puppet Server needs a certificate that proves it's allowed to use that name; if a server shows a certificate that doesn't include its hostname, Puppet agents will refuse to trust it. If you use a single hostname for Puppet traffic but load-balance it to multiple Puppet Servers, each of those servers needs to include the official hostname in its list of extra names.
Note: The list of alternate names is locked in when the server's certificate is signed. If you need to change the list later, you can't just change this setting; you also need to:
puppet cert clean <NAME>)
puppet agent -t --ca_server <CA HOSTNAME>to request a new certificate
puppet cert sign --allow-dns-alt-names <NAME>).
puppet agent -t --ca_server <CA HOSTNAME>to retrieve the cert.
To see all the alternate names your servers are using, log into your CA server
puppet cert list -a, then check the output for
(alt names: ...).
Most agent nodes should NOT have alternate names; the only certs that should
have them are Puppet Server nodes that you want other agents to trust.
list - List certificates and/or certificate requests.:
puppet ca list [--[no-]all] [--[no-]pending] [--[no-]signed] [--digest ALGORITHM] [--subject PATTERN]
This will list the current certificates and certificate signing requests in the Puppet CA. You will also get the fingerprint, and any certificate verification failure reported.
Include all certificates and requests.
--digest ALGORITHM - The hash algorithm to use when displaying the fingerprint
--[no-]pending - Include pending certificate signing requests.
--[no-]signed - Include signed certificates.
--subject PATTERN - Only include certificates or requests where subject matches PATTERN.
PATTERN is interpreted as a regular expression, allowing complex filtering of the content.
puppet ca print
Print the full-text version of a host's certificate.
revoke - Add certificate to certificate revocation list.:
puppet ca revoke
Add certificate to certificate revocation list.
sign - Sign an outstanding certificate request.:
puppet ca sign [--[no-]allow-dns-alt-names]
Sign an outstanding certificate request.
Whether or not to accept DNS alt names in the certificate request
verify - Verify the named certificate against the local CA certificate.:
puppet ca verify
Verify the named certificate against the local CA certificate.
