Using FusionAuth on Docker

FusionAuth Docker containers can be used with Docker Compose, Kubernetes, Helm or OpenShift.

The following example is using Docker Compose. Here are kubernetes installation instructions, which use Helm. Find links for OpenShift and other community supported environments in the FusionAuth Contrib GitHub repo.

Docker Compose

All of the FusionAuth Docker images may be found on Docker Hub.

The FusionAuth Docker Compose yaml files may be found on FusionAuth containers repository and more examples in the FusionAuth Docker Compose example repository described in more detail below.

If you’re looking for a complete configuration to get up and running quickly, use our Docker Compose example. docker-compose.yml will install FusionAuth with OpenSearch, but you can switch between the different search engines.

Installing FusionAuth

To use FusionAuth download the docker-compose.yml and the .env files and then start up the configured containers.

Download the FusionAuth docker files

curl -o docker-compose.yml https://raw.githubusercontent.com/FusionAuth/fusionauth-containers/master/docker/fusionauth/docker-compose.yml
curl -o .env https://raw.githubusercontent.com/FusionAuth/fusionauth-containers/master/docker/fusionauth/.env

Edit these files as needed. The stock .env file will contain the following values, you will want to modify the DATABASE_PASSWORD and ensure the POSTGRES_USER and POSTGRES_PASSWORD values are correct. You may also override any of these values using environment variables.

The .env file

DATABASE_USERNAME=fusionauth
DATABASE_PASSWORD=hkaLBM3RVnyYeYeqE3WI1w2e4Avpy0Wd5O3s3
FUSIONAUTH_APP_MEMORY=512M
FUSIONAUTH_APP_RUNTIME_MODE=development
OPENSEARCH_JAVA_OPTS="-Xms512m -Xmx512m"
POSTGRES_USER=postgres
POSTGRES_PASSWORD=postgres

Starting FusionAuth

docker compose up -d
docker compose logs -f

Now you can visit http://localhost:9011 and configure FusionAuth.

The Docker Compose Files

The following is the default docker-compose.yml file, which installs FusionAuth.

Docker Services

In the above example configurations there are three services:

  • database
  • search
  • fusionauth

Let’s look at each of these.

Database Service

The database service provides a PostgreSQL database for use by FusionAuth.

You will need to either set the POSTGRES_PASSWORD environment variable in the db service section, or, more ideally, set the value in the host environment and only reference it in the docker-compose.yml file.

By default this database is not accessible outside of the Docker Compose containers, but you may expose the port if you want to examine the database by adding the ports mapping in the service definition.

Review the other properties to ensure they meet your requirements.

Note: If you plan to use MySQL please review the Limitations for the FusionAuth docker images.

Search Service

Elasticsearch Versions >= 7.6.1 and <= 7.17.x are currently supported. Later versions may work as well but may not have been tested for compatibility.

OpenSearch version 2.x should also function properly with FusionAuth version >= 1.42.0.

The RAM required by Elasticsearch or OpenSearch depends on your login volume and user/entity counts. If you expect to have a few logins per minute and only a few thousand users/entities, 1GB-2GB of RAM will be sufficient. If you have more users/entities as well as logins, please size up accordingly. We recommend running load tests of FusionAuth to help determine the amount of RAM that is required for your needs.

The FusionAuth Service

This is the service that runs the FusionAuth application.

Review the Configuration documentation to customize your deployment. The best way to configure FusionAuth when using Docker is to use environment variables as documented in that link.

In addition, the port 9011 is mapped between the container and your host machine. This may be modified if you want to run more than one FusionAuth instance or for any other reason.

Other Services

You may add other services to the Docker Compose files if needed.

For example, in development environments it can be helpful to run MailCatcher which provides a local SMTP server. This allows FusionAuth to send transactional emails for account verification, password reset, and others.

Example docker-compose.yml with mailcatcher

version: '3'

Upgrading

To upgrade FusionAuth when running with docker compose:

  1. Stop the instance: docker compose down.
  2. Modify the docker-compose.yml file to point to the version of FusionAuth you want. You can see available tags.
  3. Start it up: docker compose up -d.
  4. Log in to the administrative UI.

Migrations

If there were database migrations required, what happens on an upgrade depends on two settings: the runtime mode and the silent mode.

Prior to version 1.19.0, migration behavior was different. See below for more.

If silent mode is set to true, then database migrations will automatically be performed.

If silent mode is false and the runtime mode is set to development, then the maintenance mode screen will pop up and you will be prompted to complete the migrations there.

In all other cases the migrations will not be applied, and you’ll have to perform them yourself. If you want to manage your own database upgrades, performing the SQL migrations out of band with another tool or process is a good option.

When Are Database Migrations Applied

Runtime ModeSilent ModeMigration Behavior
developmenttrueMigration applied automatically
developmentfalseMaintenance mode UI displayed, user prompted to run migrations
productiontrueMigration applied automatically
productionfalseMigration never applied by FusionAuth, must be applied out of band

See the configuration reference or the silent mode guide for more information. To apply the database migrations out of band see the database upgrade documentation.

Prior to 1.19

If the installation is in production mode, apply the migrations out of band.

When running in development runtime mode, silent mode was enabled based upon the presence of environment variables, such as the database user, and could not explicitly be enabled or disabled.

Docker Tags

The Docker Compose file references the latest tag, but that tag is not dynamic. It is only the latest at a point in time. To get the most recently released image, you have a couple of options.

  • Pull the latest image with this command: docker pull fusionauth/fusionauth-app:latest or docker compose pull and recreate your deployment with docker compose up -d which will recreate every container where a new image is available.
  • Edit the Docker Compose file and specify a specific version. This is a good idea for a production deployment. With docker compose pull you can only pull the specified image, or just run docker compose up -d which will pull the image and recreate the container at the same time.
  • Remove all images with docker rmi <IMAGE ID> selected from the list of IMAGE IDs which you can show with docker images. This requires that the image isn’t used and therefore may prompt you to remove containers using it. Since all state of FusionAuth is stored in the database, and for docker you use volumes to persist data, you can safely remove the containers. After that you can use docker compose pull, docker compose build and docker compose up -d accordingly to get images specified the in the docker-compose.yml.

To generally clean up your images on your system ,docker image prune will remove all unused, dangling images.

Custom Docker Images

If you want to build your own image starting with our base image, start with the fusionauth/fusionauth-app image. Just as the FusionAuth Docker image is based on the ubuntu:jammy image, you can build a Docker file which is based on the fusionauth/fusionauth-app:latest image. This can be useful if you want to permanently add a password hashing plugin, configuration file, or other customization directly in to the image.

Example Dockerfile for building fusionauth-app including a plugin

FROM maven AS build
WORKDIR /app
RUN git init . &&\
  git remote add -t \* -f origin https://github.com/FusionAuth/fusionauth-example-password-encryptor.git &&\
  git checkout master &&\
  mvn compile package

FROM fusionauth/fusionauth-app:latest
COPY --chown=fusionauth:fusionauth --from=build /app/target/fusionauth-example-password-encryptor*.jar /usr/local/fusionauth/plugins/

With this example, you can use docker compose build to only run the build steps in the referenced Dockerfile. This will create you a custom Docker image which is consequentially used in the creation of the container in Docker Compose when running docker compose up -d. Alternatively you can run only docker compose up -d which will automatically take care of the build as well if not present.

By default the build process will cache a lot of the steps, to force a fresh build you can run docker compose build --pull --no-cache instead.

Here’s the FusionAuth application Dockerfile as a reference which builds the fusionauth/fusionauth-app base image.

The FusionAuth Docker file

#

Kickstart

Using Docker with Kickstart is a powerful combination. Using these technologies together lets you:

  • Configure and share development environments
  • Create replicable bug reports
  • Spin up auth instances with a well known, versioned set of data for continuous integration and testing

All the normal limitations of Kickstart apply (the Kickstart will not run if the database has already been set up with an API key, for example).

It’s easy to get started with Kickstart, but you’ll need to tweak your Docker Compose files a bit. Before you begin, you’ll need a valid kickstart.json file. Note that this file could be called anything, kickstart.json is simply a convention. Check out the Kickstart documentation for more information on writing one.

Once you have a valid kickstart.json file, create a subdirectory in the location of your docker-compose.yml file. It can be named anything; this documentation will use a directory called kickstart. Next, you’ll mount this directory and set the FUSIONAUTH_APP_KICKSTART_FILE variable in the docker-compose.yml file.

Here are the steps to do so:

  • In the volumes: section of the fusionauth service, add - ./kickstart:/usr/local/fusionauth/kickstart.
  • Modify .env and add the Kickstart configuration variable: FUSIONAUTH_APP_KICKSTART_FILE=/usr/local/fusionauth/kickstart/kickstart.json. This path should be what the Docker container expects, not the path on the host.
  • Configure docker-compose.yml to pass the environment variable set by .env to the container. Do this by adding FUSIONAUTH_APP_KICKSTART_FILE: ${FUSIONAUTH_APP_KICKSTART_FILE} to the environment section of the fusionauth service.
  • docker compose up -d

The following is an example docker-compose.yml file configuring FusionAuth to run the commands in a kickstart.json at startup.

After running docker compose up -d you should see a line similar to the one below in the logs. These logs can be accessed using this command: docker compose logs -f fusionauth:

FusionAuth log messages indicating Kickstart has succeeded

io.fusionauth.api.service.system.kickstart.KickstartRunner - Summary

This indicates that Kickstart completed and provides a summary of the configuration changes made by it.

You may also want to check out the Isolated Docker Setups if you want the ability to rapidly stand up different versions and configurations of FusionAuth.

If you want to test changes to your Kickstart file, you’ll need to delete your volumes each time. Kickstart won’t run except on a brand new install. If there is any data in the database, it won’t proceed.

This will delete all data in your docker instance.

Deleting the volumes

docker compose down -v

Plugins

Instead of building a custom docker image, you can directly mount a directory containing a plugin to your Docker container.

Here are the steps to do so:

  • In the volumes: section of the fusionauth service, add - ./plugins:/usr/local/fusionauth/plugins.
  • Copy your plugin jar file, created by following the instructions, to your plugins directory on the host.
  • docker compose up -d

The following is an example docker-compose.yml file configuring FusionAuth to scan for plugins at startup.

INFO  io.fusionauth.api.plugin.guice.PluginModule - Plugin successfully installed

Such output indicates that the plugin has been installed and can be used.

Accessing the Host Machine

The default FusionAuth Docker configuration sets up the network using the bridge configuration. This means that all the hosts defined by docker-compose.yml can access each other. However, it means that any applications running on your host machine cannot be accessed by FusionAuth using localhost.

This is typically only an issue when FusionAuth is accessing resources outside of the Docker network to, for example, send email or request a webhook. If a Rails application is running locally on a Mac and you want FusionAuth, running in Docker, to send a webhook payload to it, localhost won’t work.

In this situation, do one of the following:

  • For macOS and Windows hosts, you can use host.docker.internal as the hostname instead of localhost.
  • For Linux hosts, add extra_hosts: - "host.docker.internal:host-gateway" to your docker-compose.yml.
  • Run a container with your application in Docker
  • Install FusionAuth on the host machine, using FastPath or another method

Modifying the FusionAuth service in docker-compose.yml to use other Docker networking schemes such as host may work, but isn’t fully tested or supported.

OpenSearch Production Deployment Configuration

Production runtime requirements and configuration for OpenSearch will drastically differ from the Docker Compose examples as the examples are configured without any security or redundancy.

Please review the Installing OpenSearch documentation for further details around production deployment.

Elasticsearch Production Deployment Configuration

Elasticsearch has a few runtime requirements that may not be met by default on your host platform. Please review the Elasticsearch Docker production mode guide for more information.

For example if startup is failing and you see the following in the logs, you will need to increase vm.max_map_count on your host VM.

The log message when max_map_count is too low

Limitations

Due to Oracle licensing restrictions, the docker images published on Docker Hub do not contain the necessary software to connect to a MySQL database.

If you wish to use MySQL, you’ll need to build a custom container that includes the MySQL Connector JAR file. Here is an example container definition that uses the FusionAuth image as a base layer and adds the MySQL connector.

Example Dockerfile which downloads the MySQL connector

#
# FusionAuth App Dockerfile including the MySQL connector
#
# Note:
# -----------------------------------------------------------------------------
# The MySQL JDBC connector is not bundled with FusionAuth due to the GPL
# license terms under which Oracle publishes this software.
#
# Because of this restriction, you will need to build a docker image for your
# use that contains the MySQL JDBC connector in order to connect to a MySQL
# database at runtime.
