Chainguard Container for wildfly

WildFly is a lightweight and open-source application server designed for deploying and running Java applications.

Chainguard Containers are regularly-updated, secure-by-default container images.

Download this Container Image

For those with access, this container image is available on cgr.dev:

docker pull cgr.dev/ORGANIZATION/wildfly:latest

Be sure to replace the ORGANIZATION placeholder with the name used for your organization's private repository within the Chainguard Registry.

Compatibility Notes

Chainguard's WildFly image is comparable to the official WildFly image. Note that, as of this writing, the entrypoint of Chainguard's WildFly image has diverged from the upstream image (quay.io/wildfly/wildfly) to bind to management interfaces over 0.0.0.0 instead of the default (-bmanagement=0.0.0.0). This change was necessary to ensure compatibility with Helm Chart version 2.4.0 (release link), as both Chainguard's image and the upstream image were failing without this modification.

This issue will be resolved once PR #143 is merged into the WildFly Charts repository.

Getting Started

To start a WildFly container using the Chainguard image, run the following command:

docker run --rm --name wildfly-container -p 9990:9990 -p 8080:8080 -it cgr.dev/ORGANIZATION/wildfly:latest

You can verify the container is running with a docker ps command:

docker ps | grep wildfly-container

To check if Wildfly has started successfully, check the logs with docker logs:

docker logs wildfly-container | grep "Started server"

You can deploy a sample WAR application to WildFly. First use curl to download a sample application from the Apache Tomcat website:

curl -sSL -o sample.war https://tomcat.apache.org/tomcat-10.1-doc/appdev/sample/sample.war

Then deploy the application:

docker cp sample.war wildfly-container:/opt/jboss/wildfly/standalone/deployments

Verify the deployment:

docker exec wildfly-container ls -l /opt/jboss/wildfly/standalone/deployments | grep sample.war

Once deployed, confirm that the sample application is accesible:

curl -s http://localhost:8080/sample/ | grep "Hello, World"

To remove the WildFly container:

docker rm -f wildfly-container

What are Chainguard Containers?

Chainguard Containers are minimal container images that are secure by default.

In many cases, the Chainguard Containers tagged as :latest contain only an open-source application and its runtime dependencies. These minimal container images typically do not contain a shell or package manager. Chainguard Containers are built with Wolfi, our Linux undistro designed to produce container images that meet the requirements of a more secure software supply chain.

The main features of Chainguard Containers include:

• Minimal design, without unnecessary software bloat
• Daily builds to ensure container images are up-to-date with available security patches
• High quality build-time SBOMs attesting to the provenance of all artifacts within the image
• Verifiable signatures provided by Sigstore
• Reproducible builds with Cosign and apko (read more about reproducibility)

For cases where you need container images with shells and package managers to build or debug, most Chainguard Containers come paired with a -dev variant.

Although the -dev container image variants have similar security features as their more minimal versions, they feature additional software that is typically not necessary in production environments. We recommend using multi-stage builds to leverage the -dev variants, copying application artifacts into a final minimal container that offers a reduced attack surface that won’t allow package installations or logins.
