I dumped a lot of code without much documentation and optimization. There are LOTS OF things to improve. I am now losing write access to this repository. And I will keep working on this even after this Hackathon. Further work will be continued at https://github.com/gyuho/runetcd.

Currently this works well locally, but I ran out of time deploying to public. I will fix it later. See below for more details.

Distributed Reliable Key-Value Store etcd Visualized

runetcd runs, demos etcd with CLIs and dashboards.

• Why
• 10-second Demo
• Dashboard for production
• Credits
• Progress

↑ top

• http://try.redis.io
• http://play.golang.org

So must etcd be easy to try and play.

Public demo here https://runetcd.io. (Fixing DNS issue right now. Please run locally for now. Sorry)

Please visit http://23.236.62.97:8000/ in the meantime.

It runs exactly the same etcd cluster as in production. Each client launches N number of machines and writes to the distributed database.

Distributed database does A LOT OF RPC calls. So it's very easy to overload runetcd.io, even though it has resources limits that can be used. To experience full-powered etcd, PLEASE run CLI locally. And here's how:

go get -v github.com/gophergala2016/runetcd
runetcd demo-web -b $GOPATH/src/github.com/gophergala2016/runetcd/bin/etcd

# or specify your etcd binary path

# or to run quick simulation in terminal
runetcd demo
# cluster start, fail, recover, stress, put, range, watch, ...

It's that easy! Just etcd binary and internet connection for javascript libraries. In the future, I may get rid of javascript dependency using https://github.com/rakyll/statik.

You can use this as an etcd dashboard:

go get -v github.com/gophergala2016/runetcd
runetcd dashboard

# and type your etcd client endpoints

Need to figure out web socket issue... but running out of time...

Almost done. Dashboard, demo-web both working good.

Finish dashboard backend.

Outlined dashboard frontend.

Added etcdctlv3 interface!

Re-organize packages.

Add help page!

and break time...

Real-time metrics graphs up and running!

Better node status display!

Got some realtime updates, logs up and running!

CLI demo done!
