Customize Docker Images

Edit on GitHubEdit MD

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 an Ubuntu container 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 to the image.

Here's a Dockerfile which extends the latest FusionAuth 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/

Here's an example docker compose YAML file which uses this new image:

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

#
# FusionAuth App Dockerfile
#
# Build:
#   > docker pull ubuntu:noble
#   > docker buildx build --platform=linux/arm64 -t fusionauth/fusionauth-app:1.68.0 .
#   > docker buildx build --platform=linux/arm64 -t fusionauth/fusionauth-app:latest .
#
# Note: Substitute your target platform architecture. The above example is targetting a 64-bit ARM platform.
#       To target an Intel based platform use --platform=linux/amd64.
#       By default, the build will fetch the fusionauth artifact from the public download location. If you have a local copy of the artifact,
#       place it in the same directory as this Dockerfile and name it fusionauth-app-<version>.zip. The build will detect the local file and
#       use it instead of downloading it.
#
# Run:
#  > docker run -p 9011:9011 -it fusionauth/fusionauth-app
#
# Publish:
#   > docker push fusionauth/fusionauth-app:1.68.0
#   > docker push fusionauth/fusionauth-app:latest

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).

To use Kickstart, you'll need to tweak your Docker Compose files. Before you begin, you'll need a valid kickstart.json file (the kickstart.json name is just a convention). Check out the Kickstart documentation for more information on writing a kickstart.json.

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.

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.

caution

This will delete all data in your docker instance.

Delete 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.

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

Access 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. For example, if an application is running locally and you want FusionAuth, running in Docker, to send a webhook payload to it, configuring FusionAuth to send the webhook to localhost won't work. localhost in the Docker container refers to the Docker container itself, not the host machine.

In this situation, do one of the following:

Run a container with your application in Docker, and use the appropriate network domain name.
Install FusionAuth on the host machine and use localhost.
Use an alias address, host.docker.internal, as the hostname instead of localhost.
- For macOS and Windows hosts, you can use host.docker.internal without any additional configuration.
- For Linux hosts, add the following lines to your docker-compose.yml:
docker-compose.yml
```
extra_hosts: 
  - "host.docker.internal:host-gateway"
```

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.

# License: https://github.com/mysql/mysql-connector-j/blob/release/8.0/LICENSE
# Homepage: https://dev.mysql.com/doc/connector-j/8.0/en/
#
# If you choose to build a Docker image containing this connector, ensure you
# are aware and in compliance with the license under which the MySQL JDBC connector
# is provided.
#
# This file is provided as an example only.
