Nutch Dockerfile

This directory contains a Dockerfile of Nutch 2.X for Docker.

What is Nutch?

Apache Nutch is a highly extensible and scalable open source web crawler software project.

Nutch can run on a single machine, but gains a lot of its strength from running in a Hadoop cluster

Docker Image

Current configuration of this image consists of components:

• Apache Hadoop 2.5.1
• Apache HBase 0.98.8-hadoop2
• Apache Nutch 2.X HEAD (this will ensure that you are always running off of bleeding edge)

Base Image

• stackbrew/ubuntu:saucy

Installation

1. Install Docker.

2a. Download automated build from public hub registry docker pull nutch/nutch_with_hbase_hadoop

2b. Build from files in this directory:

$(boot2docker shellinit)
docker build -t <new name for image> .

Usage

Start docker

boot2docker up
$(boot2docker shellinit)

Start an image and enter shell. First command will start image and will print on stdout standard logs.

IMAGE_PID=$(docker run -i -t  nutch_with_hbase_hadoop)
docker exec -i -t $IMAGE_PID bash

Nutch is located in /opt/nutch/ and is almost ready to run. Review configuration in /opt/nutch/conf/ and you can start crawling.

echo 'http://nutch.apache.org' > seed.txt
/opt/nutch/bin/nutch inject seed.txt
/opt/nutch/bin/nutch generate -topN 10 -- this will return batchId
/opt/nutch/bin/nutch fetch <batchId>
/opt/nutch/bin/nutch parse <batchId>
/opt/nutch/bin/nutch updatedb <batchId>
