Apache Solr image built from the Ansible Role geerlingguy.solr
Full Description

Apache Solr (Built with Ansible Container)

This project is in it's early stages. There will be bugs! You may be better served using the official Solr Docker image if it meets your requirements.

This project is composed of three main parts:

  • Ansible Container project: This project is maintained on GitHub: geerlingguy/solr-container. Please file issues, support requests, etc. against this GitHub repository.
  • Docker Hub Image: If you just want to use the geerlingguy/solr Docker image in your project, you can pull it from Docker Hub.
  • Ansible Role: If you need a flexible Ansible role that's compatible with both traditional servers and containerized builds, check out geerlingguy.solr on Ansible Galaxy. (This is the Ansible role that does the bulk of the work in managing the Apache Solr container.)

Versions

Currently maintained versions include:

  • 6.x, 6.6.1, latest: Apache Solr 6.x
  • 5.x, 5.5.4: Apache Solr 5.x
  • 4.x, 4.10.4: Apache Solr 4.x
  • 3.x, 3.6.2: Apache Solr 3.x

Standalone Usage

If you want to use the geerlingguy/solr image from Docker Hub, you can quickly build a Solr container locally with:

docker run -d --name=solr -p 8983:8983 geerlingguy/solr:latest /opt/solr/bin/solr start -p 8983 -s /var/solr -f -force

(For Solr 4.x, drop the final -force argument.)

You can also wrap up that configuration in a Dockerfile and/or a docker-compose.yml file if you want to keep things simple. For example:

```
version: "3"

services:
  solr:
    image: geerlingguy/solr:latest
    container_name: solr
    ports:
      - "8983:8983"
    restart: always
    # See 'Custom and Persistent Solr cores' for instructions for volumes.
    volumes: []
    command: ["/opt/solr/bin/solr", "start", "-p", "8983", "-s", "/var/solr", "-f", "-force"]

Then run:

docker-compose up -d

Now you should be able to access the Solr admin dashboard at http://localhost:8983/.

Custom and Persistent Solr cores

The default installation includes a collection1 core in the SOLR_HOME directory, /var/solr.

Apache Solr will autodiscover any Solr cores in SOLR_HOME by searching for core.properties files inside each subdirectory. A standard convention for a single Solr core is to to mount a host directory as a volume with the core directory, containing the core's conf, data, and core.properties files.

Here's an example minimal core.properties file, for a core named mysearch:

name=mysearch
config=solrconfig.xml
schema=schema.xml
dataDir=data

So, if you have a solr core directory named mysearch (with a mysearch/core.properties file inside, and a conf and data directory for storing Solr configuration and index data, respectively), mount it as a volume like -v ./mysearch:/var/solr/mysearch:rw. If you have multiple solr cores (all defined inside a cores directory), mount them inside a cores directory like -v ./cores:/var/solr/cores.

Or, if using a Docker Compose file:

services:
  solr:
    ...
    volumes:
      # If you have one core:
      - ./mysearch:/var/solr/mysearch:rw
      # If you have multiple cores:
      - ./cores:/var/solr/cores:rw

You can also mount volumes from a data container or elsewhere; the key is you will be able to both provide custom Solr configuration (schema.xml, solrconfig.xml, etc.), and also have a persistent data directory that lives outside the container.

Apache Solr 3.x

There are a number of differences to keep in mind if using Apache Solr 3.x:

  • Apache Solr 3.x doesn't support core.properties or core autodiscovery, so if you want to use a custom Solr core configuration, you should mount a volume into /opt/solr/example/solr with your Solr core configuration (conf and data dirs, at minimum).
  • At this time, multicore isn't officially supported under 3.x in this Docker container.
  • Apache Solr 3.x doesn't run in the foreground in the same way as 4+. You have to use the command java -jar start.jar inside the directory /opt/solr/example to start Solr in the foreground.
