#Zookeeper 3.4.6
This Docker image is running a Zookeeper 3.4.6 server. It can be cluster-enabled by passing an environment variable `ZOOKEEPER_HOSTS` with a list of comma-separated hosts:
192.168.0.1:2888:3888,192.168.0.2:2888:3888,192.168.0.3:2888:3888
e.g. if you want to run different Zookeeper instances on different Docker hosts. Be sure expose the relevant ports (`2181`, `2888` and `3888`).
## Configuration
To run a "plain" Zookeper instance without cluster support, the image can be started with
$ docker run -d \
--name zookeeper \
--net=host \
-p 2181:2181 \
-p 2888:2888 \
-p 3888:3888 \
tobilg/zookeeper
If you want to dynmically configure a cluster, the image can be run with (Debian/Ubuntu-based hosts)
$ docker run -d \
--name zookeeper \
--net=host \
-e ZOOKEEPER_HOSTS=192.168.0.1:2888:3888,192.168.0.2:2888:3888,192.168.0.3:2888:3888 \
-e LOCAL_ZK_IP=$(/usr/bin/ip -o -4 addr list eth0 | grep global | awk '{print $4}' | cut -d: -f1) \
-p 2181:2181 \
-p 2888:2888 \
-p 3888:3888 \
tobilg/zookeeper
RedHat/CentOS/Fedora-based hosts' `LOCAL_ZK_IP` line need to replaced with
-e LOCAL_ZK_IP=$(/sbin/ifconfig eth0 | grep 'inet ' | awk '{print $2}') \
The `LOCAL_ZK_IP` must be provided to be matched to the hosts contained in `ZOOKEEPER_HOSTS` for the generation of the `myid` file (see [Zookeeper docs](http://zookeeper.apache.org/doc/trunk/zookeeperStarted.html#sc_RunningReplicatedZooKeeper)).
Be sure to replace `eth0` with the "public" network interface.
