FIPS Notes

The mediamtx binary in this image is built with the Chainguard Go FIPS toolchain. All TLS and symmetric crypto operations route through the FIPS-validated OpenSSL provider activated by openssl-config-fipshardened.

Encrypted Config

mediamtx's upstream encrypted-config feature uses nacl/secretbox (XSalsa20 + Poly1305), neither of which is FIPS-approved. The FIPS variant replaces this with AES-256-GCM. Users encrypting configs for the FIPS image must produce base64(12-byte nonce || AES-256-GCM ciphertext) with a 32-byte key (MTX_CONFKEY is zero-padded or truncated to 32 bytes, same as upstream).

Plain (unencrypted) YAML configs work unchanged.

Variants

Both variants publish to the same OCI repo — the ffmpeg-bundled flavor is distinguished by an -ffmpeg tag suffix.

What are Chainguard Containers?

Chainguard's free tier of Starter container images are built with Wolfi, our minimal Linux undistro.

All other Chainguard Containers are built with Chainguard OS, Chainguard's minimal Linux operating system 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 development, or -dev, variant.

In all other cases, including Chainguard Containers tagged as :latest or with a specific version number, the container images include only an open-source application and its runtime dependencies. These minimal container images typically do not contain a shell or package manager.

Although the -dev container image variants have similar security features as their more minimal versions, they include additional software that is typically not necessary in production environments. We recommend using multi-stage builds to copy artifacts from the -dev variant into a more minimal production image.

Need additional packages?

To improve security, Chainguard Containers include only essential dependencies. Need more packages? Chainguard customers can use Custom Assembly to add packages, either through the Console, chainctl, or API.

To use Custom Assembly in the Chainguard Console: navigate to the image you'd like to customize in your Organization's list of images, and click on the Customize image button at the top of the page.
