NAME¶cf-runagent - activate cf-agent on a remote host
SYNOPSIS¶cf-runagent [OPTION]... [FILE]
DESCRIPTION¶cf-runagent connects to a list of running instances of cf-serverd. It allows foregoing the usual cf-execd schedule to activate cf-agent. Additionally, a user may send classes to be defined on the remote host. Two kinds of classes may be sent: classes to decide on which hosts cf-agent will be started, and classes that the user requests cf-agent should define on execution. The latter type is regulated by cf-serverd's role based access control.
- --help, -h
- Print the help message
- --background, -b value
- Parallelize connections (50 by default)
- --debug, -d
- Enable debugging output
- --verbose, -v
- Output verbose information about the behaviour of cf-runagent
- --log-level, -g value
- Specify how detailed logs should be. Possible values: 'error', 'warning', 'notice', 'info', 'verbose', 'debug'
- --dry-run, -n
- All talk and no action mode - make no changes, only inform of promises not kept
- --version, -V
- Output the version of the software
- --file, -f value
- Specify an alternative input file than the default. This option is overridden by FILE if supplied as argument.
- --define-class, -D value
- Define a list of comma separated classes to be sent to a remote agent
- --select-class, -s value
- Define a list of comma separated classes to be used to select remote agents by constraint
- --inform, -I
- Print basic information about changes made to the system, i.e. promises repaired
- --remote-options, -o value
- --diagnostic, -x
- --hail, -H value
- Hail the following comma-separated lists of hosts, overriding default list
- --interactive, -i
- Enable interactive mode for key trust
- --timeout, -t value
- Connection timeout, seconds
- --color, -C value
- Enable colorized output. Possible values: 'always', 'auto', 'never'. If option is used, the default value is 'auto'
- --timestamp, -l
- Log timestamps on each line of log output
- --log-modules, -? value
- Enable even more detailed debug logging for specific areas of the implementation. Use together with '-d'. Use --log-modules=help for a list of available modules
- --remote-bundles, -? value
- Bundles to execute on the remote agent
CFENGINE¶CFEngine provides automated configuration management of large-scale computer systems. A system administrator describes the desired state of a system using CFEngine policy code. The program cf-agent reads policy code and attempts to bring the current system state to the desired state described. Policy code is downloaded by cf-agent from a cf-serverd daemon. The daemon cf-execd is responsible for running cf-agent periodically.
Documentation for CFEngine is available at http://cfengine.com/documentation/.
PROMISE THEORY¶CFEngine is built on principles from promise theory, proposed by Mark Burgess in 2004. Promise theory is a model of voluntary cooperation between individual, autonomous actors or agents who publish their intentions to one another in the form of promises. A promise is a declaration of intent whose purpose is to increase the recipient's certainty about a claim of past, present or future behaviour. For a promise to increase certainty, the recipient needs to trust the promiser, but trust can also be built on the verification that previous promises have been kept, thus trust plays a symbiotic relationship with promises.
