This removes some boilerplate from the Watch methods which can be baked into the engine instead. This code should be checked for races and locks to make sure we only start resources when it makes sense to.
mgmt: next generation config management!
Community:
Come join us on IRC in #mgmtconfig on Freenode! You may like the #mgmtconfig hashtag if you're on Twitter.
Status:
Mgmt is a fairly new project. We're working towards being minimally useful for production environments. We aren't feature complete for what we'd consider a 1.x release yet. With your help you'll be able to influence our design and get us there sooner!
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:
- Make sure you have golang version 1.6 or greater installed.
- If you do not have a GOPATH yet, create one and export it:
mkdir $HOME/gopath
export GOPATH=$HOME/gopath
- You might also want to add the GOPATH to your
~/.bashrcor~/.profile. - For more information you can read the GOPATH documentation.
- Next download the mgmt code base, and switch to that directory:
go get -u github.com/purpleidea/mgmt
cd $GOPATH/src/github.com/purpleidea/mgmt
- Get the remaining golang deps with
go get ./..., or runmake depsif you're comfortable with how we install them. - Run
make buildto get a freshly builtmgmtbinary. - Run
time ./mgmt run --yaml examples/graph0.yaml --converged-timeout=5 --tmp-prefixto 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: the manually created documentation.md (also available as PDF) and the automatically generated GoDoc documentation.
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.
