💖 CF-EXECD(8) 💖

okay bestie, we're doing this — it's a page from the System Manager's Manual, and it lives in the System Administration section. Let's GO 🦋

✨ NAME ✨

cf-execd — the scheduling daemon for cf-agent. she's the one who keeps the calendar 📅

✨ SYNOPSIS ✨

cf-execd [OPTION]...  [FILE]

✨ DESCRIPTION ✨

so cf-execd is literally the scheduling daemon for cf-agent. she runs cf-agent locally according to a schedule that's specified in policy code (the executor control body, iykyk).

after a cf-agent run finishes, cf-execd gathers up the output from cf-agent, and she can be configured to email that output to a specified address 📧. she can also be configured to splay (that's randomize, bestie) the execution schedule, so you don't get a million synchronized cf-agent runs all across your network at the exact same second 💀

not me forgetting the glow-up: this daemon reloads its config when the SIGHUP signal is received. periodt.

✨ OPTIONS ✨

  • --help, -h — print the help message 🫶
  • --debug, -d — enable debugging output 🐛
  • --verbose, -v — output verbose info about how cf-execd is behaving (she's an open book, fr fr)
  • --dry-run, -n — all talk and no action mode 💅 makes no changes, only informs you of promises not kept
  • --version, -V — output the version of the software
  • --file, -f value — specify an alternative input file than the default. heads up: this option gets overridden by FILE if you supply it as an argument 👑
  • --define, -D value — define a list of comma separated classes to be defined at the start of execution
  • --negate, -N value — define a list of comma separated classes to be undefined at the start of execution
  • --no-lock, -K — ignore locking constraints during execution (ifelapsed/expireafter) if it's "too soon" to run 🙈
  • --inform, -I — print basic information about changes made to the system, i.e. promises repaired
  • --diagnostic, -x — activate internal diagnostics (developers only 🧑‍💻)
  • --log-level, -g value — specify how detailed logs should be. possible values: 'error', 'warning', 'notice', 'info', 'verbose', 'debug'
  • --no-fork, -F — run as a foreground process (do not fork)
  • --once, -O — run once and then exit (this implies no-fork)
  • --no-winsrv, -W — do not run as a service on windows — use this when running from a command shell (CFEngine Nova only) 🪟
  • --ld-library-path, -L value — set the internal value of LD_LIBRARY_PATH for child processes
  • --color, -C value — enable colorized output 🌈 possible values: 'always', 'auto', 'never'. if the option is used, the default value is 'auto'
  • --timestamp, -l — log timestamps on each line of log output ⏰
  • --ignore-preferred-augments, - — ignore def_preferred.json file in favor of def.json
  • --skip-db-check, - value — do not run database integrity checks and repairs at startup
  • --with-runagent-socket, - value — specify the directory for the socket for runagent requests, or 'no' to disable the socket

✨ 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. and the daemon cf-execd is the one responsible for running cf-agent periodically. that's her whole job bestie, and she eats every time 🔥

documentation for CFEngine is available at https://docs.cfengine.com/.

✨ 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, so trust plays a symbiotic relationship with promises 🫶✨
