intropro/zookeeper repository overview

⁠Zookeeper Dockerfile

Zookeeper⁠ is a centralized service for maintaining configuration information, naming, providing distributed synchronization, and providing group services.

⁠Description

This docker file based on:

The following actions will be performed by docker build:

  • install the additional packages (git, ant, wget, tar, vim, mc, unzip, lsof)
  • zookeeper home set to /opt/zookeeper
  • zookeeper logs will be placed into /opt/zookeeper/logs
  • zookeeper dataDir will be placed into $ZOO_HOME/data/snapshot
  • zookeeper dataLogDir will be placed into $ZOO_HOME/data/transaction
  • delete all unused files (.git/ .revision/ docs/ src/ .git* *.txt *.xml build/ bin/*.txt bin/*.cmd lib/*.txt /lib/cobertura)
  • set TERM=xterm
⁠Build an image

If you'd like to build an own image, then you should perform the following actions:

cd /tmp
git clone https://github.com/intropro/zookeeper-docker.git
cd zookeeper-docker/git checkout 3.4.9
git checkout 3.4.9
docker build -t zookeeper:3.4.9 .
rm -rf /tmp/zookeeper-docker
⁠Run a container
⁠Quick start as a standalone server
docker run -d --network host --name <YOUR_CONTAINER_NAME> intropro/zookeeper:latest

Example:

docker run -d --network host --name zookeeper intropro/zookeeper:latest
⁠Quick start a simple cluster (three dedicated hosts)

Host #1

docker run -d -e MYID=1 -e ZOO_SERVERS="server.<MYID>=<HOST1>:<FOLLOWER_PORT>:<LEADER_ELECTION_PORT> server.<MYID>=<HOST2>:<FOLLOWER_PORT>:<LEADER_ELECTION_PORT> server.<MYID>=<HOST3>:<FOLLOWER_PORT>:<LEADER_ELECTION_PORT>" --network host --name <YOUR_CONTAINER_NAME> intropro/zookeeper:latest

Host #2

docker run -d -e MYID=2 -e ZOO_SERVERS="server.<MYID>=<HOST1>:<FOLLOWER_PORT>:<LEADER_ELECTION_PORT> server.<MYID>=<HOST2>:<FOLLOWER_PORT>:<LEADER_ELECTION_PORT> server.<MYID>=<HOST3>:<FOLLOWER_PORT>:<LEADER_ELECTION_PORT>" --network host --name <YOUR_CONTAINER_NAME> intropro/zookeeper:latest

Host #3

docker run -d -e MYID=3 -e ZOO_SERVERS="server.<MYID>=<HOST1>:<FOLLOWER_PORT>:<LEADER_ELECTION_PORT> server.<MYID>=<HOST2>:<FOLLOWER_PORT>:<LEADER_ELECTION_PORT> server.<MYID>=<HOST3>:<FOLLOWER_PORT>:<LEADER_ELECTION_PORT>" --network host --name <YOUR_CONTAINER_NAME> intropro/zookeeper:latest

Example:

Host #1

docker run -d -e MYID=1 -e ZOO_SERVERS="server.1=host1.local.com:2888:3888 server.2=host2.local.com:2888:3888 server.3=host3.local.com:2888:3888" --network host --name zookeeper intropro/zookeeper:latest

Host #2

docker run -d -e MYID=2 -e ZOO_SERVERS="server.1=host1.local.com:2888:3888 server.2=host2.local.com:2888:3888 server.3=host3.local.com:2888:3888" --network host --name zookeeper intropro/zookeeper:latest

Host #3

docker run -d -e MYID=3 -e ZOO_SERVERS="server.1=host1.local.com:2888:3888 server.2=host2.local.com:2888:3888 server.3=host3.local.com:2888:3888" --network host --name zookeeper intropro/zookeeper:latest
⁠Quick start a simple cluster (the similar host)

Example:

Host

docker run -d -e MYID=1 -e ZOO_CLIENT_PORT=2181 -e ZOO_SERVERS="server.1=host.local.com:2888:3888 server.2=host.local.com:2889:3889 server.3=host.local.com:2890:3890" --network host --name zookeeper-1 intropro/zookeeper:latest
docker run -d -e MYID=2 -e ZOO_CLIENT_PORT=2182 -e ZOO_SERVERS="server.1=host.local.com:2888:3888 server.2=host.local.com:2889:3889 server.3=host.local.com:2890:3890" --network host --name zookeeper-2 intropro/zookeeper:latest
docker run -d -e MYID=3 -e ZOO_CLIENT_PORT=2183 -e ZOO_SERVERS="server.1=host.local.com:2888:3888 server.2=host.local.com:2889:3889 server.3=host.local.com:2890:3890" --network host --name zookeeper-3 intropro/zookeeper:latest

Please be aware that launch zookeeper cluster on a single host will not create any redundancy. It's acceptable only for development and test purposes. Multiple hosts on dedicated servers are required for PROD mode.

⁠Supported environment variables

You can pass the following variables to the container:

  • JMXPORT - start a container with JMX port. Default value - none.
  • ZOO_CLIENT_PORT - start a container with your own clientPort. Default value - 2181.
  • ZOO_LOG4J_PROP - start a container with your own log4j properties. Default value - "INFO,CONSOLE,ROLLINGFILE".
  • JVMFLAGS - you can use this variable to configure JVM. For example you can dafine a JVM heap size. Default value - empty.
  • ZOO_LOG_DIR - define where zookeeper logs will be placed. Default value - $ZOO_HOME/logs.
  • MYID - define myid. Required only for cluster mode. Default value - none.
  • ZOO_SERVERS - define members for zookeeper cluster. Required only for cluster mode. Format server.MYID=HOSTNAME:FOLLOWER_PORT:LEADER_ELECTION_PORT Default value - none.
  • JMXLOCALONLY - Default value - false.
  • JMXDISABLE - Default value - false.
  • JMXAUTH - Default value - false.
  • JMXSSL - Default value - false.
  • JMXLOG4J - Default value - true.
⁠Use extarnal volumes to store transaction log and snapshot files

You can use external volumes to store transaction log and snapshot files.

Create a folder for dataDir and dataLogDir on the localhost.

mkdir -p /volumes/sdb1/zookeeper/data

Run a docker container (example for standalone mode):

docker run -d -v /volumes/sdb1/zookeeper/data:/opt/zookeeper/data --network host --name zookeeper intropro/zookeeper:latest

###Manage a container A list of running containers.

docker ps

A list of all containers.

docker ps -a

start/stop/stats one or more containers

docker start <YOUR_CONTAINER_NAME>
docker stop <YOUR_CONTAINER_NAME>
docker stats <YOUR_CONTAINER_NAME>
