Chainguard Container for ant-fips

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/ant-fips:latest

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

Compatibility Notes

The Chainguard ant container image provides Apache Ant, a Java-based build automation tool. Since there is no official Apache Ant Docker image, this image serves as a secure alternative to community-maintained versions.

This container image's tags are in the form of <ANT_VERSION>-jdk<OPENJDK_VERSION>[-dev], such that one can track 1-jdk21 for Ant 1.x.x with OpenJDK 21. The -dev variants contain jmods, and are thus suitable to use jlink.

FIPS Support

The ant-fips Chainguard Container ships with a validated redistribution of OpenSSL's FIPS provider module.

Note, exclude bc-fips.jars /usr/share/java/bouncycastle-fips/ module-path from jlink, as jlink is unable to link signed jars. Instead ensure that --module-path=/usr/share/java/bouncycastle-fips is used at runtime, with such path copied from either this container image, or jdk-fips or jre-fips images.

OpenJDK 8 is not currently supported for FIPS; with this image, one must target at least JDK 11 during build. Refer to the Specification tab for the extra variables set to ensure Ant and Java are operating in FIPS mode.

For more on FIPS support in Chainguard Containers, consult the guide on FIPS-enabled Chainguard Containers on Chainguard Academy.

Getting Started

Use the ant-fips container to build Java projects with Ant build files:

docker run --rm -v $(pwd):/workspace -w /workspace cgr.dev/ORGANIZATION/ant-fips:latest

To compile and package a Java project:

docker run --rm -v $(pwd):/workspace -w /workspace cgr.dev/ORGANIZATION/ant-fips:latest compile jar

To run a specific Ant target:

docker run --rm -v $(pwd):/workspace -w /workspace cgr.dev/ORGANIZATION/ant-fips:latest [target-name]

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.
