Apache Zookeeper on Docker

In this repository you will find a docker file which will allow for running apache zookeeper inside docker containers.

##Pull the image from Docker Repository

docker pull bzcareer/docker-zookeeper

Building the image

Navigate to the bin directory and run

cd bin
./make-all.sh

or via docker commands:

docker build --rm -t bzcareer/docker-zookeeper .

Environment Variables

ZK_ID

• Optional only required for replicated mode.
• Note: Each server in the list will be mapped in the order and first server must have a ZK_ID of 1. Followed by second server with ZK_ID of 2, etc...

-e "ZK_ID=1"

ZK_SERVERS_LIST

• Optional only required for replicated mode.
• Must be a comma separated list of all kubernetes service ip address you would like to cluster and run zookeeper on.

-e "ZK_SERVERS_LIST=192.0.0.1,172.30.143.165,192.0.0.3"

Running the image in docker standalone

• if using boot2docker make sure your VM has more than 2GB memory for single standalone mode:

docker run -it -P  -h zookeeper-1 bzcareer/docker-zookeeper

or for clustermode:

docker run -e "ZK_SERVERS_LIST=172.30.143.165,172.30.143.166,172.30.143.167" -it -P  -h zookeeper-1 bzcareer/docker-zookeeper

Note: Make sure you created your kubernetes services which zookeeper will try to connect to.

Running on kubernetes/openshift-origin

To speed things up a bit pull down the docker image from dockerhub:

docker pull bzcareer/docker-zookeeper

[ cassanda-admin@localhost] $ oc new-project cloudanalytics
Now using project "cloudcassandra" on server "https://10.2.2.2:8443".
...

• Execute oc create -f zookeeper.pod.json

• Execute oc create -f zookeeper.service.json

• Create a route via webconsole:

http://zookeeper-d-<PROJECT_NAME>.apps.10.2.2.2.xip.io/commands/stats Note: replace <PROJECT_NAME> with the actual project you create if it is not 'cloudanalytics'

There are lots of options:

http://zookeeper-d-cloudanalytics.apps.10.2.2.2.xip.io/commands/

This Example Should Not Be Used In Production

This is just an experiment so I hope you do not use in production.
