Bitnami package for Apache Solr

What is Apache Solr?

Apache Solr is an extremely powerful, open source enterprise search platform built on Apache Lucene. It is highly reliable and flexible, scalable, and designed to add value very quickly after launch.

Overview of Apache Solr Trademarks: This software listing is packaged by Bitnami. The respective trademarks mentioned in the offering are owned by the respective companies, and use of them does not imply any affiliation or endorsement.

TL;DR

docker run --name solr bitnami/solr:latest

You can find the available configuration options in the Environment Variables section.

Why use Bitnami Images?

  • Bitnami closely tracks upstream source changes and promptly publishes new versions of this image using our automated systems.
  • With Bitnami images the latest bug fixes and features are available as soon as possible.
  • Bitnami containers, virtual machines and cloud images use the same components and configuration approach - making it easy to switch between formats based on your project needs.
  • All our images are based on minideb -a minimalist Debian based container image that gives you a small base container image and the familiarity of a leading Linux distribution- or scratch -an explicitly empty image-.
  • All Bitnami images available in Docker Hub are signed with Notation. Check this post to know how to verify the integrity of the images.
  • Bitnami container images are released on a regular basis with the latest distribution packages available.

Looking to use Apache Solr in production? Try VMware Tanzu Application Catalog, the commercial edition of the Bitnami catalog.

Only latest stable branch maintained in the free Bitnami catalog

Starting December 10th 2024, only the latest stable branch of any container will receive updates in the free Bitnami catalog. To access up-to-date releases for all upstream-supported branches, consider upgrading to Bitnami Premium. Previous versions already released will not be deleted. They are still available to pull from DockerHub.

Please check the Bitnami Premium page in our partner Arrow Electronics for more information.

Supported tags and respective Dockerfile links

Learn more about the Bitnami tagging policy and the difference between rolling tags and immutable tags in our documentation page.

You can see the equivalence between the different tags by taking a look at the tags-info.yaml file present in the branch folder, i.e bitnami/ASSET/BRANCH/DISTRO/tags-info.yaml.

Subscribe to project updates by watching the bitnami/containers GitHub repo.

Get this image

The recommended way to get the Bitnami solr Docker Image is to pull the prebuilt image from the Docker Hub Registry.

docker pull bitnami/solr:latest

To use a specific version, you can pull a versioned tag. You can view the list of available versions in the Docker Hub Registry.

docker pull bitnami/solr:[TAG]

If you wish, you can also build the image yourself by cloning the repository, changing to the directory containing the Dockerfile and executing the docker build command. Remember to replace the APP, VERSION and OPERATING-SYSTEM path placeholders in the example command below with the correct values.

git clone https://github.com/bitnami/containers.git
cd bitnami/APP/VERSION/OPERATING-SYSTEM
docker build -t bitnami/APP:latest .

Persisting your application

If you remove the container all your data and configurations will be lost, and the next time you run the image the database will be reinitialized. To avoid this loss of data, you should mount a volume that will persist even after the container is removed.

For persistence you should mount a volume at the /bitnami path. The above examples define a docker volume namely solr_data. The Solr application state will persist as long as this volume is not removed.

To avoid inadvertent removal of this volume you can mount host directories as data volumes. Alternatively you can make use of volume plugins to host the volume data.

docker run -v /path/to/solr-persistence:/bitnami bitnami/solr:latest

or by modifying the docker-compose.yml file present in this repository:

solr:
  ...
  volumes:
    - /path/to/solr-persistence:/bitnami
  ...

NOTE: As this is a non-root container, the mounted files and directories must have the proper permissions for the UID 1001.

Connecting to other containers

Using Docker container networking, a Solr server running inside a container can easily be accessed by your application containers.

Containers attached to the same network can communicate with each other using the container name as the hostname.

Using the Command Line

Step 1: Create a network

docker network create solr-network --driver bridge

Step 2: Launch the solr container within your network

Use the --network <NETWORK> argument to the docker run command to attach the container to the solr-network network.

docker run --name solr-node1 --network solr-network bitnami/solr:latest

Step 3: Run another containers

We can launch another containers using the same flag (--network NETWORK) in the docker run command. If you also set a name to your container, you will be able to use it as hostname in your network.

Using a Docker Compose file

When not specified, Docker Compose automatically sets up a new network and attaches all deployed services to that network. However, we will explicitly define a new bridge network named solr-network.

version: '2'

networks:
  solr-network:
    driver: bridge

services:
  solr-node1:
    image: bitnami/solr:latest
    networks:
      - solr-network
    ports:
      - '8983:8983'
  solr-node2:
    image: bitnami/solr:latest
    networks:
      - solr-network
    ports:
      - '8984:8984'

Then, launch the containers using:

docker-compose up -d

When you start the solr image, you can adjust the configuration of the instance by passing one or more environment variables either on the docker-compose file or on the docker run command line.

Specifying Environment Variables using Docker Compose

This requires a minor change to the docker-compose.yml file present in this repository:

solr:
  ...
  environment:
    - SOLR_CORES=my_core
  ...

Specifying Environment Variables on the Docker command line

docker run -d -e SOLR_CORES=my_core --name solr bitnami/solr:latest
Using your Apache Solr Cores configuration files

In order to load your own configuration files, you will have to make them available to the container. You can do it mounting a volume in the desired location and setting the environment variable with the customized value (as it is pointed above, the default value is data_driven_schema_configs).

Using Docker Compose

This requires a minor change to the docker-compose.yml file present in this repository:

solr:
  ...
  environment:
    - SOLR_CORE_CONF_DIR=/container/path/to/your/confDir
  volumes:
    - '/local/path/to/your/confDir:/container/path/to/your/confDir'
  ...

Logging

The Bitnami solr Docker image sends the container logs to the stdout. To view the logs:

docker logs solr

or using Docker Compose:

docker-compose logs solr

You can configure the containers logging driver using the --log-driver option if you wish to consume the container logs differently. In the default configuration docker uses the json-file driver.

Maintenance

Upgrade this image

Bitnami provides up-to-date versions of solr, including security patches, soon after they are made upstream. We recommend that you follow these steps to upgrade your container.

Step 1: Get the updated image

docker pull bitnami/solr:latest

or if you're using Docker Compose, update the value of the image property to bitnami/solr:latest.

Step 2: Stop and backup the currently running container

Stop the currently running container using the command

docker stop solr

or using Docker Compose:

docker-compose stop solr

Next, take a snapshot of the persistent volume /path/to/solr-persistence using:

rsync -a /path/to/solr-persistence /path/to/solr-persistence.bkp.$(date +%Y%m%d-%H.%M.%S)

You can use this snapshot to restore the database state should the upgrade fail.

Step 3: Remove the currently running container

docker rm -v solr

or using Docker Compose:

docker-compose rm -v solr

Step 4: Run the new image

Re-create your container from the new image, restoring your backup if necessary.

docker run --name solr bitnami/solr:latest

or using Docker Compose:

docker-compose up solr

Notable Changes

8.11.3-debian-12-r2 and 9.5.0-debian-12-r7
  • Remove HDFS modules due to CVEs
8.8.0-debian-10-r11
  • Adds SSL support.
8.8.0-debian-10-r9
  • The Solr container initialization logic has been moved to Bash scripts.
  • The size of the container image has been decreased.
  • Added the support for cloud mode.
  • Added support for authentication and admin user creation.
  • Data migration for the upgrades. If you are running an older version of this container, run this version as user root and it will migrate your current data.
7.4.0-r23
  • The Solr container has been migrated to a non-root user approach. Previously the container ran as the root user and the Solr daemon was started as the solr user. From now on, both the container and the Solr daemon run as user 1001. As a consequence, the data directory must be writable by that user. You can revert this behavior by changing USER 1001 to USER root in the Dockerfile.
