The naming was confusing because the boolean return value expresses whether the resource needed changing (the check failed) as opposed to the state not being not OK. purpleidea note: The "stateok" (now properly renamed to "checkok") is actually the historical bool return value of the Check() -> bool function which is now part of the CheckApply() amalgamation. This is an easy way to think about it if you're trying to understand why at the end of a successful apply we return false, nil.

Community:
Come join us on IRC in #mgmtconfig on Freenode! You may like the #mgmtconfig hashtag if you're on Twitter.
Questions:
Please join the #mgmtconfig IRC community! If you have a well phrased question that might benefit others, consider asking it by sending a patch to the documentation FAQ section. I'll merge your question, and a patch with the answer!
Quick start:
- Either get the golang dependencies on your own, or run
make depsif you're comfortable with how we install them. - Run
make buildto get a freshly builtmgmtbinary. - Run
cd $(mktemp --tmpdir -d tmp.XXX) && etcdto get etcd running. Themgmtsoftware will do this automatically for you in the future. - Run
time ./mgmt run --file examples/graph0.yaml --converged-timeout=1to try out a very simple example! - To run continuously in the default mode of operation, omit the
--converged-timeoutoption. - Have fun hacking on our future technology!
Examples:
Please look in the examples/ folder for more examples!
Documentation:
Please see: DOCUMENTATION.md or PDF.
Roadmap:
Please see: TODO.md for a list of upcoming work and TODO items. Please get involved by working on one of these items or by suggesting something else! Feel free to grab one of the straightforward #mgmtlove issues if you're a first time contributor to the project or if you're unsure about what to hack on!
Bugs:
Please set the DEBUG constant in main.go to true, and post the logs when you report the issue.
Bonus points if you provide a shell or OMV reproducible test case.
Feel free to read my article on debugging golang programs.
Dependencies:
-
golang 1.4 or higher (required, available in most distros)
-
golang libraries (required, available with
go get)go get github.com/coreos/etcd/client go get gopkg.in/yaml.v2 go get gopkg.in/fsnotify.v1 go get github.com/codegangsta/cli go get github.com/coreos/go-systemd/dbus go get github.com/coreos/go-systemd/util -
stringer (required for building), available as a package on some platforms, otherwise via
go getgo get golang.org/x/tools/cmd/stringer -
pandoc (optional, for building a pdf of the documentation)
-
