Updates on WildFly Docker Images

By Jeff Mesnil | November 10, 2022

In this article, we give an update on changes made to the WildFly Docker images to enhance their capabilities.

Thanks to contributions from Henri-Laiho and Kris-Gerhard, we have updated the images to use the JDK images from Eclipse Temurin as their base images. This provides the following highly requested capabilities:

Provides multiarch images. The WildFly images now support linux/arm64 in addition to linux/amd64
Supports Long-Term Support (LTS) JDK 11 & 17
Supports the latest non-LTS JDK (19 at the moment)
Base images that are frequently updated to fix OS and JDK vulnerabilities

We are using the centos7 variants of the Temurin images, so there are no Operating System changes compared to the existing images.

Docker Images for WildFly 27 and future releases

Now that WildFly publishes images to run the application server with different JDK versions, we are updating our tag convention to reflect that change: the tag of the image now identifies the version of WildFly as well as the JDK version.

For each release of WildFly (e.g. 27.0.0.Final), there are fixed tags for each provided JDK version:

quay.io/wildfly/wildfly:27.0.0.Final-jdk11
quay.io/wildfly/wildfly:27.0.0.Final-jdk17

There are also floating tags available to pull the latest release of WildFly on the various JDK:

quay.io/wildfly/wildfly:latest-jdk11
quay.io/wildfly/wildfly:latest-jdk17

Finally, there is the latest tag that corresponds to the latest release of WildFly on the latest LTS JDK (17 at the moment).

quay.io/wildfly/wildfly:latest

Note	This floating tag may correspond to a different JDK version in future releases of WildFly images. Instead of using this `latest` tag, we recommend to use the floating tag with the JDK version mention to guarantee the use of the same JDK version across WildFly releases (e.g. `latest-jdk17`).

The tags page shows a visual representation of the tags that clearly identifies tags corresponding to the same image.

Docker Images for WildFly 26 (and Jakarta EE 8)

We are using these new tags starting with WildFly 27 releases which require applications to be built with Jakarta EE 10.

However, there is also benefit to the new images for users that are staying on WildFly 26 (which is the last release of WildFly that supports Jakarta EE 8). We will also provide new images for WildFLy 26 that leverages these new capabilities. The tags for WildFly 26 will be:

quay.io/wildfly/wildfly:26.1.2.Final-jdk11
quay.io/wildfly/wildfly:26.1.2.Final-jdk17

Provide non-LTS JDK images

With the move to the Temurin images, we are also able to provide images for non-LTS JDK versions.

In order to help using the latest features of Java with WildFly, we will also provide images for the latest non-LTS JDK version tested by WildFly. At the time of writing, this is JDK 19. The tags for these images will be:

quay.io/wildfly/wildfly:27.0.0.Final-jdk19
quay.io/wildfly/wildfly:latest-jdk19

These non-LTS images will have a shorter life: as soons as WildFly supports a more recent non-LTS JDK version, we will provide images for this version and stop producing images for the previous version.

Summary

WildFly now provides Docker images with highly requested features such as ARM architecture, multiple JDK versions and frequently updated base images that lets users pick and choose the best settings adapted to their Jakarta applications when they are deployed on the cloud.
