PUPPET-AGENT(8) OpenVox manual PUPPET-AGENT(8) NAME puppet-agent - The puppet agent daemon provided by OpenVox SYNOPSIS Retrieves the client configuration from the OpenVox server and applies it to the local host. This service may be run as a daemon, run periodically using cron (or some- thing similar), or run interactively for testing purposes. USAGE puppet agent [--certname NAME] [-D|--daemonize|--no-daemonize] [-d|--debug] [--detailed-exitcodes] [--digest DIGEST] [--disable [MESSAGE]] [--enable] [--fingerprint] [-h|--help] [-l|--logdest syslog|eventlog|ABS FILEPATH|con- sole] [--serverport PORT] [--noop] [-o|--onetime] [--sourceaddress IP_AD- DRESS] [-t|--test] [-v|--verbose] [-V|--version] [-w|--waitforcert SECONDS] DESCRIPTION This is the main puppet client. Its job is to retrieve the local machine's configuration from a remote server and apply it. In order to successfully communicate with the remote server, the client must have a certificate signed by a certificate authority that the server trusts; the recommended method for this, at the moment, is to run a certificate authority as part of the puppet server (which is the default). The client will connect and request a signed certificate, and will continue connecting until it re- ceives one. Once the client has a signed certificate, it will retrieve its configura- tion and apply it. USAGE NOTES 'puppet agent' does its best to find a compromise between interactive use and daemon use. If you run it with no arguments and no configuration, it goes into the background, attempts to get a signed certificate, and re- trieves and applies its configuration every 30 minutes. Some flags are meant specifically for interactive use -- in particular, 'test', 'tags' and 'fingerprint' are useful. '--test' runs once in the foreground with verbose logging, then exits. It also exits if it can't get a valid catalog. --test includes the '--de- tailed-exitcodes' option by default and exits with one of the following exit codes: * 0: The run succeeded with no changes or failures; the system was al- ready in the desired state. * 1: The run failed, or wasn't attempted due to another run already in progress. * 2: The run succeeded, and some resources were changed. * 4: The run succeeded, and some resources failed. * 6: The run succeeded, and included both changes and failures. '--tags' allows you to specify what portions of a configuration you want to apply. Puppet elements are tagged with all of the class or definition names that contain them, and you can use the 'tags' flag to specify one of these names, causing only configuration elements contained within that class or definition to be applied. This is very useful when you are testing new con- figurations -- for instance, if you are just starting to manage 'ntpd', you would put all of the new elements into an 'ntpd' class, and call puppet with '--tags ntpd', which would only apply that small portion of the con- figuration during your testing, rather than applying the whole thing. '--fingerprint' is a one-time flag. In this mode 'puppet agent' runs once and displays on the console (and in the log) the current certificate (or certificate request) fingerprint. Providing the '--digest' option allows you to use a different digest algorithm to generate the fingerprint. The main use is to verify that before signing a certificate request on the mas- ter, the certificate request the master received is the same as the one the client sent (to prevent against man-in-the-middle attacks when signing cer- tificates). '--skip_tags' is a flag used to filter resources. If this is set, then only resources not tagged with the specified tags will be applied. Values must be comma-separated. OPTIONS Note that any Puppet setting that's valid in the configuration file is also a valid long argument. For example, 'server' is a valid setting, so you can specify '--server servername' as an argument. Boolean settings accept a '--no-' prefix to turn off a behavior, translating into '--setting' and '--no-setting' pairs, such as --daemonize and --no-daemonize. See the configuration file documentation at https://puppet.com/docs/pup- pet/latest/configuration.html for the full list of acceptable settings. A commented list of all settings can also be generated by running puppet agent with '--genconfig'. * --certname: Set the certname (unique ID) of the client. The master reads this unique identifying string, which is usually set to the node's fully-qualified domain name, to determine which configurations the node will receive. Use this option to debug setup problems or im- plement unusual node identification schemes. (This is a Puppet setting, and can go in puppet.conf.) * --daemonize: Send the process into the background. This is the default. (This is a Puppet setting, and can go in puppet.conf. Note the special 'no-' prefix for boolean settings on the command line.) * --no-daemonize: Do not send the process into the background. (This is a Puppet setting, and can go in puppet.conf. Note the special 'no-' pre- fix for boolean settings on the command line.) * --debug: Enable full debugging. * --detailed-exitcodes: Provide extra information about the run via exit codes; works only if '--test' or '--onetime' is also specified. If en- abled, 'puppet agent' uses the following exit codes: 0: The run succeeded with no changes or failures; the system was al- ready in the desired state. 1: The run failed, or wasn't attempted due to another run already in progress. 2: The run succeeded, and some resources were changed. 4: The run succeeded, and some resources failed. 6: The run succeeded, and included both changes and failures. * --digest: Change the certificate fingerprinting digest algorithm. The default is SHA256. Valid values depends on the version of OpenSSL in- stalled, but will likely contain MD5, MD2, SHA1 and SHA256. * --disable: Disable working on the local system. This puts a lock file in place, causing 'puppet agent' not to work on the system until the lock file is removed. This is useful if you are testing a configuration and do not want the central configuration to override the local state until everything is tested and committed. Disable can also take an optional message that will be reported by the 'puppet agent' at the next disabled run. 'puppet agent' uses the same lock file while it is running, so no more than one 'puppet agent' process is working at a time. 'puppet agent' exits after executing this. * --enable: Enable working on the local system. This removes any lock file, causing 'puppet agent' to start managing the local system again However, it continues to use its normal scheduling, so it might not start for another half hour. 'puppet agent' exits after executing this. * --evaltrace: Logs each resource as it is being evaluated. This allows you to interactively see exactly what is being done. (This is a Puppet setting, and can go in puppet.conf. Note the special 'no-' prefix for boolean settings on the command line.) * --fingerprint: Display the current certificate or certificate signing request fingerprint and then exit. Use the '--digest' option to change the digest algorithm used. * --help: Print this help message * --job-id: Attach the specified job id to the catalog request and the report used for this agent run. This option only works when '--onetime' is used. When using Puppet Enterprise this flag should not be used as the orchestrator sets the job-id for you and it must be unique. * --logdest: Where to send log messages. Choose between 'syslog' (the POSIX syslog service), 'eventlog' (the Windows Event Log), 'console', or the path to a log file. If debugging or verbosity is enabled, this defaults to 'console'. Otherwise, it defaults to 'syslog' on POSIX sys- tems and 'eventlog' on Windows. Multiple destinations can be set using a comma separated list (eg: /path/file1,console,/path/file2)" A path ending with '.json' will receive structured output in JSON for- mat. The log file will not have an ending ']' automatically written to it due to the appending nature of logging. It must be appended manually to make the content valid JSON. A path ending with '.jsonl' will receive structured output in JSON Lines format. * --masterport: The port on which to contact the Puppet Server. (This is a Puppet setting, and can go in puppet.conf. Deprecated in favor of the 'serverport' setting.) * --noop: Use 'noop' mode where the daemon runs in a no-op or dry-run mode. This is useful for seeing what changes Puppet would make without actually executing the changes. (This is a Puppet setting, and can go in puppet.conf. Note the special 'no-' prefix for boolean settings on the command line.) * --onetime: Run the configuration once. Runs a single (normally daemo- nized) Puppet run. Useful for interactively running puppet agent when used in conjunction with the --no-daemonize option. (This is a Puppet setting, and can go in puppet.conf. Note the special 'no-' prefix for boolean settings on the command line.) * --serverport: The port on which to contact the Puppet Server. (This is a Puppet setting, and can go in puppet.conf.) * --sourceaddress: Set the source IP address for transactions. This de- faults to automatically selected. (This is a Puppet setting, and can go in puppet.conf.) * --test: Enable the most common options used for testing. These are 'onetime', 'verbose', 'no-daemonize', 'no-usecacheonfailure', 'de- tailed-exitcodes', 'no-splay', and 'show_diff'. * --trace Prints stack traces on some errors. (This is a Puppet setting, and can go in puppet.conf. Note the special 'no-' prefix for boolean settings on the command line.) * --verbose: Turn on verbose reporting. * --version: Print the puppet version number and exit. * --waitforcert: This option only matters for daemons that do not yet have certificates and it is enabled by default, with a value of 120 (seconds). This causes 'puppet agent' to connect to the server every 2 minutes and ask it to sign a certificate request. This is useful for the initial setup of a puppet client. You can turn off waiting for cer- tificates by specifying a time of 0. (This is a Puppet setting, and can go in puppet.conf.) * --write_catalog_summary After compiling the catalog saves the resource list and classes list to the node in the state directory named classes.txt and resources.txt (This is a Puppet setting, and can go in puppet.conf.) EXAMPLE $ puppet agent --server puppet.domain.com DIAGNOSTICS Puppet agent accepts the following signals: SIGHUP Restart the puppet agent daemon. SIGINT and SIGTERM Shut down the puppet agent daemon. SIGUSR1 Immediately retrieve and apply configurations from the puppet mas- ter. SIGUSR2 Close file descriptors for log files and reopen them. Used with logrotate.
