etcd image for docker build on nuagebec/ubuntu:14.04 image

etcd, a highly-available key value store for shared configuration and service discovery.
etcd is inspired by Apache ZooKeeper and doozer, with a focus on being:

  • Simple: curl'able user facing API (HTTP+JSON)
  • Secure: optional SSL client cert authentication
  • Fast: benchmarked 1000s of writes/s per instance
  • Reliable: properly distributed using Raft

etcd is written in Go and uses the Raft consensus algorithm to manage a highly-available replicated log.

Use etcdctl for a simple command line client.
Or, feel free to just use curl, as in the example below :

/data/persistent to persist

Running

Note : using ETCD discovery URL as docker env. variable is mandatory (for now)

A simply way to obtain this variable is using this script

#/bin/sh
# If env. var. named ETCD_DISCOVERY isn't set, discover it
if [[ -z "$ETCD_DISCOVERY" ]]
then ETCD_DISCOVERY=$(wget https://discovery.etcd.io/new  -O - ) && \
     export ETCD_DISCOVERY ; fi

launching nuagebec/etcd

As discovery URL, starting your own is suggested.
https://github.com/coreos/etcd/blob/master/Documentation/2.0/clustering.md#etcd-discovery

To bootstrap a cluster for discovery, use this URL to retreive a Profile and it's configuration :
https://github.com/mikefaille/etcd-static-bootstrap

After, start docker using "docker-env-file" generated by "./gen-pub-discovery-URL.sh <cluster size>" ( this script erase and create new env. file each times) :

docker run -d -p 4001:4001 -p 7001:7001 -env-file docker_env_file   nuagebec/etcd:latest
