The recommended way to get the Bitnami Discourse Docker Image is to pull the prebuilt image from the Docker Hub Registry.
docker pull bitnami/discourse: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/discourse:[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 .
Discourse requires access to a PostgreSQL database to store information. We'll use the Bitnami Docker Image for PostgreSQL for the database requirements.
Step 1: Create a network
docker network create discourse-network
Step 2: Create a volume for PostgreSQL persistence and create a PostgreSQL container
$ docker volume create --name postgresql_data
docker run -d --name postgresql \
--env ALLOW_EMPTY_PASSWORD=yes \
--env POSTGRESQL_USERNAME=bn_discourse \
--env POSTGRESQL_PASSWORD=bitnami123 \
--env POSTGRESQL_DATABASE=bitnami_discourse \
--network discourse-network \
--volume postgresql_data:/bitnami/postgresql \
bitnami/postgresql:latest
Step 3: Create a volume for Redis persistence and create a Redis container
$ docker volume create --name redis_data
docker run -d --name redis \
--env ALLOW_EMPTY_PASSWORD=yes \
--network discourse-network \
--volume redis_data:/bitnami/redis \
bitnami/redis:latest
Step 4: Create volumes for Discourse persistence and launch the container
$ docker volume create --name discourse_data
docker run -d --name discourse \
-p 8080:8080 -p 8443:8443 \
--env ALLOW_EMPTY_PASSWORD=yes \
--env DISCOURSE_DATABASE_USER=bn_discourse \
--env DISCOURSE_DATABASE_PASSWORD=bitnami123 \
--env DISCOURSE_DATABASE_NAME=bitnami_discourse \
--env DISCOURSE_HOST=www.example.com \
--network discourse-network \
--volume discourse_data:/bitnami/discourse \
bitnami/discourse:latest
Step 5: Launch the Sidekiq container
docker run -d --name sidekiq \
--network discourse-network \
--volume discourse_data:/bitnami/discourse \
bitnami/discourse:latest /opt/bitnami/scripts/discourse-sidekiq/run.sh
Access your application at http://your-ip/
curl -sSL https://raw.githubusercontent.com/bitnami/containers/main/bitnami/discourse/docker-compose.yml > docker-compose.yml
docker-compose up -d
Please be aware this file has not undergone internal testing. Consequently, we advise its use exclusively for development or testing purposes. For production-ready deployments, we highly recommend utilizing its associated Bitnami Helm chart.
If you detect any issue in the docker-compose.yaml
file, feel free to report it or contribute with a fix by following our Contributing Guidelines.
If you need to run discourse administrative commands like Create admin account from console, you can do so by executing a shell inside the container and running with the proper environment variables.
cd /opt/bitnami/discourse
RAILS_ENV=production bundle exec rake admin:create
If you remove the container all your data 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 directory at the /bitnami/discourse
path. If the mounted directory is empty, it will be initialized on the first run. Additionally you should mount a volume for persistence of the PostgreSQL data.
The above examples define the Docker volumes named postgresql_data
and discourse_data
. The Discourse application state will persist as long as volumes are not removed.
To avoid inadvertent removal of volumes, you can mount host directories as data volumes. Alternatively you can make use of volume plugins to host the volume data.
This requires a minor change to the docker-compose.yml
file present in this repository:
postgresql:
...
volumes:
- - 'postgresql_data:/bitnami/postgresql'
+ - /path/to/postgresql-persistence:/bitnami/postgresql
...
redis:
...
volumes:
- - 'redis_data:/bitnami/redis'
+ - /path/to/redis-persistence:/bitnami/redis
...
discourse:
...
volumes:
- - 'discourse_data:/bitnami/discourse'
+ - /path/to/discourse-persistence:/bitnami/discourse
...
sidekiq:
...
volumes:
- - 'discourse_data:/bitnami/discourse'
+ - /path/to/discourse-persistence:/bitnami/discourse
...
-volumes:
- postgresql_data:
- driver: local
- redis_data:
- driver: local
- discourse_data:
- driver: local
Step 1: Create a network (if it does not exist)
docker network create discourse-network
Step 2. Create a PostgreSQL container with host volume
docker run -d --name postgresql \
--env ALLOW_EMPTY_PASSWORD=yes \
--env POSTGRESQL_USERNAME=bn_discourse \
--env POSTGRESQL_PASSWORD=bitnami123 \
--env POSTGRESQL_DATABASE=bitnami_discourse \
--network discourse-network \
--volume /path/to/postgresql-persistence:/bitnami/postgresql \
bitnami/postgresql:latest
Step 3. Create a Redis container with host volume
docker run -d --name redis \
--env ALLOW_EMPTY_PASSWORD=yes \
--network discourse-network \
--volume /path/to/redis-persistence:/bitnami/redis \
bitnami/redis:latest
Step 4. Create the Discourse container with host volumes
docker run -d --name discourse \
-p 8080:8080 -p 8443:8443 \
--env ALLOW_EMPTY_PASSWORD=yes \
--env DISCOURSE_DATABASE_USER=bn_discourse \
--env DISCOURSE_DATABASE_PASSWORD=bitnami123 \
--env DISCOURSE_DATABASE_NAME=bitnami_discourse \
--env DISCOURSE_HOST=www.example.com \
--network discourse-network \
--volume /path/to/discourse-persistence:/bitnami/discourse \
bitnami/discourse:latest
Step 5. Create the Sidekiq container with host volumes
docker run -d --name sidekiq \
--network discourse-network \
--volume /path/to/discourse-persistence:/bitnami/discourse \
bitnami/discourse:latest
You can mount your configuration files to the /opt/bitnami/discourse/mounted-conf
directory. Make sure that your configuration files follow the standardized names used by Discourse. Some of the most common files include:
discourse.conf
database.yml
site_settings.yml
The set of default standard configuration files may be found here. You may refer to the the Discourse webpage for further details and specific configuration guides.

When you start the Discourse 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. If you want to add a new environment variable:
For docker-compose add the variable name and value under the application section in the docker-compose.yml
file present in this repository:
discourse:
...
environment:
- DISCOURSE_PASSWORD=my_password
...
For manual execution add a --env
option with each variable and value:
$ docker run -d --name discourse -p 80:8080 -p 443:8443 \
--env DISCOURSE_PASSWORD=my_password \
--network discourse-tier \
--volume /path/to/discourse-persistence:/bitnami \
bitnami/discourse:latest
Examples
This would be an example of SMTP configuration using a Gmail account:
Modify the environment variables used for the discourse
and sidekiq
containers in the docker-compose.yml
file present in this repository:
discourse:
...
environment:
...
- DISCOURSE_SMTP_HOST=smtp.gmail.com
- DISCOURSE_SMTP_PORT=587
- DISCOURSE_SMTP_USER=your_email@gmail.com
- DISCOURSE_SMTP_PASSWORD=your_password
- DISCOURSE_SMTP_PROTOCOL=tls
...
sidekiq:
...
environment:
...
- DISCOURSE_SMTP_HOST=smtp.gmail.com
- DISCOURSE_SMTP_PORT=587
- DISCOURSE_SMTP_USER=your_email@gmail.com
- DISCOURSE_SMTP_PASSWORD=your_password
- DISCOURSE_SMTP_PROTOCOL=tls
...
For manual execution:
First, create the Discourse container:
$ docker run -d --name discourse -p 80:8080 -p 443:8443 \
--env DISCOURSE_DATABASE_USER=bn_discourse \
--env DISCOURSE_DATABASE_NAME=bitnami_discourse \
--env DISCOURSE_SMTP_HOST=smtp.gmail.com \
--env DISCOURSE_SMTP_PORT=587 \
--env DISCOURSE_SMTP_USER=your_email@gmail.com \
--env DISCOURSE_SMTP_PASSWORD=your_password \
--env DISCOURSE_SMTP_PROTOCOL=tls \
--network discourse-tier \
--volume /path/to/discourse-persistence:/bitnami \
bitnami/discourse:latest
Then, create the Sidekiq container:
$ docker run -d --name sidekiq \
--env DISCOURSE_DATABASE_USER=bn_discourse \
--env DISCOURSE_DATABASE_NAME=bitnami_discourse \
--env DISCOURSE_SMTP_HOST=smtp.gmail.com \
--env DISCOURSE_SMTP_PORT=587 \
--env DISCOURSE_SMTP_USER=your_email@gmail.com \
--env DISCOURSE_SMTP_PASSWORD=your_password \
--env DISCOURSE_SMTP_PROTOCOL=tls \
--networ
Note: the README for this container is longer than the DockerHub length limit of 25000, so it has been trimmed. The full README can be found at https://github.com/bitnami/containers/blob/main/bitnami/discourse/README.md
