Zookeeper Docker Image

The aim of this project is create/use zookeeper docker images.

Build an image

bash
export ZOO_HOME="/opt/zookeeper"
export ZOO_VERSION="3.4.10"
$docker build --build-arg ZOO_VERSION=$ZOO_VERSION --build-arg ZOO_HOME=$ZOO_HOME \
-t engapa/zookeeper:${ZOO_VERSION} .

The zk_download.sh script is used to download the suitable release. The built docker image will contain a zookeeper distribution (${ZOO_VERSION}) under the directory $ZOO_HOME.

Besides, we've added two scripts :

• zk_env.sh : Export needed env variable for setup script.
• zk_setup.sh : Configure zookeeper dynamically , based on utils-docker project

Run a container

By default the entrypoint of container is zk_env.sh. This image hasn't any CMD entry, users are the responsible for launching any command when they are going to run the container.

Let's run a zookeeper container :

bash
docker run -it -e "SETUP_DEBUG=true" engapa/zookeeper:${ZOO_VERSION}

NOTE: We've pass a SETUP_DEBUG environment variable to view the setup process of config files.

Setting up

Users can pass parameters to config files just adding environment variables with specific name patterns.

This table collects the patterns of variable names which will are written in each file:

So we can configure our zookeeper server in docker run time :

bash
$docker run -it -d -e "LOG4J_log4j_rootLogger=DEBUG, stdout"

Also you may use --env-file option to load these variables from a file.

And , of course, you could provide your own properties files directly by option -v and don't use zk_setup script.
