Apache Solr and Docker for Beginners

Apache Solr and Docker for Beginners

Introduction

It is possible to find instructions for installing Docker directly on your OS. But theres almost no reason these days not to use docker. There are plenty of docker containers for Solr, and the operation (as I will demonstrate in this article) is almost trivial. Launching a docker container from a trusted image not only saves time and effort, but leverages best-practices installation and configuration techniques, at least where official or highly trusted Dockerfiles are concerned.

In this tutorial, Ill walk through launching a docker container for Solr, attaching an external data volume, and demonstrating the successful GET and POST of data to Solr between container lifecycles.

Using the docker search command, I find that these images have already been built:

At the time of this article, the first docker image is the most popular, and has a Dockerfile with a configuration that I agree with. The image is built on top of java:8, which in turn uses dockerfile/ubuntu as the base image. I like this design approach rather than pulling the OS directly. If I ever want to extend this Dockerfile, Im generally happier to work with an underlying Debian image as well, although this isnt generally much of an issue with Docker.

The image is also well-supported, with an updated configuration for the Solr 5.1 release being released today.

Building the Image

This is an optional section, but as Ive mentioned here, I like to piggyback on Dockerfiles that Im planning to use on a project.

Given a local docker registry and multiple team members, it becomes easier to point members to the registry and a standard naming scheme for images. In this case, Im not adding any extensions to the Dockerfile at the moment, but that could always come later.

My copy looks like:

FROM makuk66/docker-solr
MAINTAINER Craig Trim "craigtrim@gmail.com"

and I build this using

$ sudo docker build -t craig/solr .

from within the directory containing my Dockerfile.

Launching a Container

I can launch a container from the image directly by typing

$ sudo docker run -d -p 8983:8983 craig/solr
691f2adee14563904996cbc465c513861860dd654a011063dc31f89660def543

This launches the container and exposes the Solr installations port 8983 on the Host port 8983.  I could use any Host port I want, and if I launch multiple containers from this image, will indeed need to select something different.


The installation can be verified via a web browser:

Fig 1: http://192.168.x.y:8983/solr

A slight problem however: if I click on "Core Admin" in the dashboard and try to add a core, I get an error:

Fig 2: SolrCore Initialization Error

And at any rate, if I was able to add a core, what would this prove?  Given the ephemeral nature of Docker containers, any data or configuration I peform will be lost when the container is closed.  Granted, I could always commit my changes to the local image, but then I seem to lose much of the value of Docker.  My Dockerfile is no longer quite as relevant, and it becomes necessary to share a local image with the rest of my team (and even between my own devices), rather than simply pointing to a script.

Attaching a Volume

If youre familiar with fundamental Java concepts (particularly within the Spring Framework) the concept of "dependency injection" may be familiar.  Logic is crafted with reliance on a component, but without the requirement of managing that components lifecycle.  And if youre not familiar with this dessign pattern, thats fine.  The docker concepts are simple enough as they stand.

Im tempted to call the attachement of data volumes to a docker image "directory injection".  The pattern is clear enough: the container relies on a given directory, or many given directories.  Now, whether these directories exist (and are configured) within the container, or on the host that the container is running on, isnt that important.

Again, given the ephemeral nature of a docker container, it is often necessary to use a data volume on the host, and make the container dependent on this.

In the case of Solr, well want to inject a directory into our container that holds a configuration for a Solr core.

We do that like this:

$ sudo docker run -p 8983:8983 -v /home/craig/solr_data/:/opt/solr/server/solr/books craig/solr

The host information is in green and the container information in orange.

In some cases (particularly when debugging, or just getting started), I avoid running a container in detached mode, and focus on the immediate log output.

As in this case:

$ sudo docker run -p 8983:8983 -v /home/craig/solr_data/:/opt/solr/server/solr/books craig/solr
