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 which gives you a small base container image and the familiarity of a leading Linux distribution.
- All Bitnami images available in Docker Hub are signed with Docker Content Trust (DCT). You can use
DOCKER_CONTENT_TRUST=1
to verify the integrity of the images. - Bitnami container images are released daily with the latest distribution packages available.

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.
$ docker build -t bitnami/solr:latest 'https://github.com/bitnami/bitnami-docker-solr.git#master:8/debian-10'
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 Docker Compose
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
Configuration
Environment variables
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. The following environment values are provided to custom Solr:
SOLR_PORT_NUMBER
: Port used by Solr server. Default: 8983SOLR_SERVER_DIRECTORY
: Specify the Solr server directory. Default: serverSOLR_CORE
: Core name to create at first run. By default, it will not create a core. (E.g.: 'my_core')SOLR_CORE_CONF_DIR
: Configuration directory to copy when creating a new core. Default: data_driven_schema_configs
Cluster related environment variables:
SOLR_CLOUD_BOOTSTRAP
: Indicates if this node is going to bootstrap the cluster. Default: noSOLR_ENABLE_CLOUD_MODE
: Enable cloud mode. Default: noSOLR_COLLECTION
: Create collection at the first run. By default, it will not create a core. (E.g.: 'my_collection')SOLR_COLLECTION_SHARDS
: Number of shards for the collection created at first run. Default: 1SOLR_COLLECTION_REPLICAS
: Number of replicas for the collection create at first run. Default: 1SOLR_NUMBER_OF_NODES
: Number of the node of the Solr cloud cluster. Default: 1SOLR_HOST
: Name of the node. If not set the node IP will be used. Default: nullSORL_ZK_SLEEP_TIME
: Sleep time when waiting for init configuration operations to finish. Default: 5SOLR_ZK_MAX_RETRIES
: Maximum retries when waitinf for init configuration operations to finish. Default: 5
Authentication related environment variables:
SOLR_ENABLE_AUTHENTICATION
: Enable the authentication, you can indicate the administrator credentiales with the following variables. Default: noSOLR_ADMIN_USERNAME
: Username for the administrator user. Default: adminSOLR_ADMIN_PASSWORD
: Password for the administrator user. Default: Bitnami
SSL related environment variables:
SOLR_SSL_ENABLED
: Indicates if solr is going to enable SSL. Default: noSOLR_SSL_KEY_STORE
: Key store file. Default: nullSOLR_SSL_KEY_STORE_PASSWORD
: Password for the key store file. Default: nullSOLR_SSL_TRUST_STORE
: Trust store file. Default: nullSOLR_SSL_TRUST_STORE_PASSWORD
: Password for the trust store file. Default: nullSOLR_SSL_CHECK_PEER_NAME
: Indicates if the peer name should be checked. Default: false
Specifying Environment Variables using Docker Compose
This requires a minor change to the docker-compose.yml
file present in this repository:
solr:
...
environment:
- SOLR_CORE=my_core
...
Specifying Environment Variables on the Docker command line
$ docker run -d -e SOLR_CORE=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
8.8.0-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 thesolr
user. From now on, both the container and the Solr daemon run as user1001
. As a consequence, the data directory must be writable by that user. You can revert this behavior by changingUSER 1001
toUSER root
in the Dockerfile.
