Big Data is one of the most trending topics in the last times. One of the existing tools for this task is Zeppelin, a Java application developed by Apache, which is an implementation of the concept known as “web notebook”, focused on the interactive data analytics with languages and technologies like Spark, R, etc.<\/p>\n

In this tutorial we will see how to set up a Docker container to run it. For this, Linux Mint 18 and Docker version 1.12.3 have been used.

Tip<\/strong>
\nYou may skip Docker\u00a0installation and jump directly to the beginning of the example<\/strong><\/a> below.<\/div>\n

1. Installation<\/h2>\n

Note<\/strong>: Docker requires a 64-bit system with a kernel version equal or higher to 3.10.<\/p>\n

We can install Docker simply via apt-get<\/code>, without the need of adding any repository, just installing the docker.io<\/code> package:<\/p>\n

sudo apt-get update\r\nsudo apt-get install docker.io<\/pre>\n
For more details, you can follow the Install Docker on Ubuntu Tutorial<\/a>.<\/p>\n
2.\u00a0Creating a Zeppelin image<\/h2>\n
Unfortunately, Apache doesn’t provide an official image for Zeppelin. So, we will have to build our own image from a Dockerfile.\u00a0The easiest way is to download from the Apache mirror<\/a>.<\/p>\n
Apache Zeppelin is a Java application, so, we will need Java installed in our container. Apart from that, we will need cURL for downloading Zeppelin from the mirror. For the simplest Zeppelin image we don’t need any other package.<\/p>\n
We will be using the following directory structure:<\/p>\n
.\r\n\u251c\u2500\u2500 Dockerfile\r\n\u2514\u2500\u2500 scripts\r\n \u2514\u2500\u2500 docker-entrypoint.sh<\/pre>\n
A Dockerfile for installing Zeppelin would just consist of:<\/p>\n
Dockerfile<\/em><\/span><\/p>\n
FROM ubuntu\r\n\r\nMAINTAINER Julen Pardo <julen.pardo@outlook.es>\r\n\r\nENV ZEPPELIN_VERSION 0.7.0\r\nENV ZEPPELIN_URL http:\/\/apache.mirror.iphh.net\/zeppelin\/zeppelin-$ZEPPELIN_VERSION\/zeppelin-$ZEPPELIN_VERSION-bin-all.tgz\r\nENV ZEPPELIN_DIR \/opt\/zeppelin\r\n\r\nENV DEBIAN_FRONTEND=noninteractive\r\n\r\nRUN apt-get update\r\n\r\nRUN apt-get install -y default-jdk \\\r\n curl\r\n\r\nRUN mkdir -p $ZEPPELIN_DIR\r\n\r\n# Download compressed Zeppelin to tmp dir, and extract contents to Zeppelin dir\r\nWORKDIR \/tmp\r\n\u00a0\r\n\r\nRUN curl $ZEPPELIN_URL | tar xfz -\r\nRUN cp -r zeppelin-$ZEPPELIN_VERSION-bin-all\/* $ZEPPELIN_DIR\r\nWORKDIR $ZEPPELIN_DIR\r\n\r\n# Create a Zeppelin user\r\nRUN useradd --home $ZEPPELIN_DIR --shell \/bin\/bash zeppelin\r\nRUN chown zeppelin:zeppelin -R $ZEPPELIN_DIR\r\n\r\nCOPY scripts\/docker-entrypoint.sh \/docker-entrypoint.sh\r\nRUN chmod 777 \/docker-entrypoint.sh\r\nENTRYPOINT [\"\/docker-entrypoint.sh\"]\r\n\r\nEXPOSE 8080<\/pre>\n
