We will have to copy the driver into our custom built solr image later.Īs the last step of configuring solr we have to add the fields we want to be able to query. Note, that the docker solr image doesn’t include the database driver. Solr will look for files in the specified directory that match the regex and add them to the classpath.

Add the following two lines inside the tag, below all the other tags. Īdditionally, we have to add two more lines to solrconfig.xml so solr knows where to look for the necessary dependencies such as the database driver. Add the following just beneath the tag, where the request handler definitions start. Next, we have to modify solrconfig.xml and add a new request handler to use the configurations we just created. We’re going to call the file db-data-config.xml and put it into the myconfig/conf directory. Now we have to create a file that contains information about the database driver, url, user and password as well as the query and the fields we want Solr to index. $ docker cp copier:/opt/solr/server/solr/configsets/_default myconfig We can get it by copying it out of a Solr container like this: $ docker create -rm -name copier solr

This isn’t very useful on its own, because the core still needs to be configured using a custom configset.Īs a starting point we will use the default configset. Since having to execute commands manually is very inconvenient, the docker solr image provides scripts that handle the job for us: $ docker run -d -p 8983:8983 -name my_solr solr solr-precreate my_core $ docker exec -it my_solr solr create_core -c my_coreįirst, we run the Solr image, then we can execute commands, such as creating a core against it. Using Docker, booting up a Solr instance is straightforward: $ docker run -d -p 8983:8983 -name my_solr solr In this article I want to present my findings by building a custom Docker image for that purpose. As I have just joined the team at Armstrong Consulting, I was encouraged to explore the capabilities of Solr within a Docker container and research ways to index existing data stored in a postgres database.
