What is Wildfly?

Wildfly, formerly known as JBoss AS, or simply JBoss, is an application server authored by JBoss, now developed by Red Hat. WildFly is written in Java, and implements the Java Platform, Enterprise Edition (Java EE) specification.

Get this image

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

docker pull bitnami/wildfly: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/wildfly:[TAG]

If you wish, you can also build the image yourself.

docker build -t bitnami/wildfly:latest https://github.com/bitnami/bitnami-docker-wildfly.git

Persisting Wildfly configurations and deployments

If you remove the container all your Wildfly configurations and application deployments will be lost. To avoid this you should mount a volume that will persist even after the container is removed.

Note! If you have already started using your Wildfly deployment, follow the steps on backing up and restoring to pull the data from your running container down to your host.

The image exposes a volume at /bitnami/wildfly for the Wildfly configurations and application deployments. For persistence you can mount a directory at this location from your host. If the mounted directory is empty, it will be initialized on the first run.

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

or using Docker Compose:

version: '2'

services:
  wildfly:
    image: 'bitnami/wildfly:latest'
    ports:
      - '8080:8080'
      - '9990:9990'
    volumes:
      - /path/to/wildfly-persistence:/bitnami/wildfly

Deploying web applications on Wildfly

The /bitnami/wildfly/data directory is configured as the Wildfly webapps deployment directory. At this location, you either copy a so-called exploded web application, i.e. non-compressed, or a compressed web application resource (.WAR) file and it will automatically be deployed by Wildfly.

Additionally a helper symlink /app is present that points to the webapps deployment directory which enables us to deploy applications on a running Wildfly instance by simply doing:

docker cp /path/to/app.war wildfly:/app

Note! You can also deploy web applications on a running Wildfly instance using the Wildfly management interface.

Accessing your Wildfly server from the host

The image exposes the application server on port 8080 and the management console on port 9990. To access your web server from your host machine you can ask Docker to map random ports on your host to the ports 8080 and 9990 of the container.

docker run --name wildfly -P bitnami/wildfly:latest

Run docker port to determine the random ports Docker assigned.

$ docker port wildfly
8080/tcp -> 0.0.0.0:32775
9990/tcp -> 0.0.0.0:32774

You can also manually specify the ports you want forwarded from your host to the container.

docker run -p 8080:8080 -p 9990:9990 bitnami/wildfly:latest

Access your web server in the browser by navigating to http://localhost:8080 to access the application server and http://localhost:9990/console to access the management console.

Accessing the command line interface

The command line management tool jboss-cli.sh allows a user to connect to the Wildfly server and execute management operations available through the de-typed management model.

The Bitnami Wildfly Docker Image ships the jboss-cli.sh client and can be launched by specifying the command while launching the container.

Connecting a client container to the Wildfly server container

Step 1: Create a network

$ docker network create wildfly-tier --driver bridge

Step 2: Launch the Wildfly server instance

Use the --network wildfly-tier argument to the docker run command to attach the Wildfly container to the wildfly-tier network.

$ docker run -d --name wildfly-server \
    --network wildfly-tier \
    bitnami/wildfly:latest

Step 3: Launch your Wildfly client instance

Finally we create a new container instance to launch the Wildfly client and connect to the server created in the previous step:

$ docker run -it --rm \
    --network wildfly-tier \
    bitnami/wildfly:latest jboss-cli.sh --controller=wildfly-server:9990  --connect

Note! You can also run the client in the same container as the server using the Docker exec command.

docker exec -it wildfly-server \
  jboss-cli.sh --controller=wildfly-server:9990 --connect

Configuration

Creating a custom user

By default, a management user named user is created with the default password bitnami. Passing the WILDFLY_PASSWORD environment variable when running the image for the first time will set the password of this user to the value of WILDFLY_PASSWORD.

Additionally you can specify a user name for the management user using the WILDFLY_USERNAME environment variable. When not specified, the WILDFLY_PASSWORD configuration is applied on the default user (user).

docker run --name wildfly \
  -e WILDFLY_USERNAME=my_user \
  -e WILDFLY_PASSWORD=my_password \
  bitnami/wildfly:latest

or using Docker Compose:

version: '2'

services:
  wildfly:
    image: 'bitnami/wildfly:latest'
    ports:
      - '8080:8080'
      - '9990:9990'
    environment:
      - WILDFLY_USERNAME=my_user
      - WILDFLY_PASSWORD=my_password

Configuration files

This image looks for Wildfly configuration files in /bitnami/wildfly/conf. You may recall from the persisting wildfly configurations and deployments section, /bitnami/wildfly is the path to the persistence volume.

Create a directory named conf/ at this location with your own configuration, or the default configuration will be copied on the first run which can be customized later.

Step 1: Run the Wildfly image

Run the Wildfly image, mounting a directory from your host.

docker run --name wildfly -v /path/to/wildfly-persistence:/bitnami/wildfly bitnami/wildfly:latest

or using Docker Compose:

version: '2'

services:
  wildfly:
    image: 'bitnami/wildfly:latest'
    ports:
      - '8080:8080'
      - '9990:9990'
    volumes:
      - /path/to/wildfly-persistence:/bitnami/wildfly

Step 2: Edit the configuration

Edit the configuration on your host using your favorite editor.

eg.

vim /path/to/wildfly-persistence/conf/standalone.xml

Step 3: Restart Wildfly

After changing the configuration, restart your Wildfly container for the changes to take effect.

docker restart wildfly

or using Docker Compose:

docker-compose restart wildfly

Logging

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

docker logs wildfly

or using Docker Compose:

docker-compose logs wildfly

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

Backing up your container

To backup your configuration and logs, follow these simple steps:

Step 1: Stop the currently running container

docker stop wildfly

or using Docker Compose:

docker-compose stop wildfly

Step 2: Run the backup command

We need to mount two volumes in a container we will use to create the backup: a directory on your host to store the backup in, and the volumes from the container we just stopped so we can access the data.

docker run --rm \
  -v /path/to/wildfly-backups:/backups \
  --volumes-from wildfly \
  busybox cp -a /bitnami/wildfly /backups/latest

or using Docker Compose:

docker run --rm \
  -v /path/to/wildfly-backups:/backups \
  --volumes-from `docker-compose ps -q wildfly` \
  busybox cp -a /bitnami/wildfly /backups/latest

Restoring a backup

Restoring a backup is as simple as mounting the backup as volumes in the container.

docker run \
  -v /path/to/wildfly-backups/latest:/bitnami/wildfly \
  bitnami/wildfly:latest

or using Docker Compose:

version: '2'

services:
  wildfly:
    image: 'bitnami/wildfly:latest'
    ports:
      - '8080:8080'
      - '9990:9990'
    volumes:
      - /path/to/wildfly-backups/latest:/bitnami/wildfly

Upgrade this image

Bitnami provides up-to-date versions of Wildfly, 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/wildfly:latest

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

Step 2: Stop and backup the currently running container

Before continuing, you should backup your container's configuration and logs.

Follow the steps on creating a backup.

Step 3: Remove the currently running container

docker rm -v wildfly

or using Docker Compose:

docker-compose rm -v wildfly

Step 4: Run the new image

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

docker run --name wildfly bitnami/wildfly:latest

or using Docker Compose:

docker-compose start wildfly

Notable Changes

10.0.0-r3

• WILDFLY_USER parameter has been renamed to WILDFLY_USERNAME.

10.0.0-r0

• All volumes have been merged at /bitnami/tomcat. Now you only need to mount a single volume at /bitnami/tomcat for persistence.
• The logs are always sent to the stdout and are no longer collected in the volume.
