Request trialCrossplane function that manages environment-specific configurations for resources in compositions with FIPS 140-3 compliance
Chainguard Containers are regularly-updated, secure-by-default container images.
For those with access, this container image is available on cgr.dev

The function-environment-configs-fips
image is based on the Crossplane function-environment-configs project. This Chainguard Image provides a secure, minimal runtime environment with the following differences from upstream images:
The function-environment-configs-fips
image is designed to work with Crossplane compositions for managing environment-specific configurations in FIPS-compliant environments. The image contains a Crossplane function that can be used to inject environment-specific settings into your resources while maintaining cryptographic compliance.
You can run the function directly to verify it's working:
Create a function definition for use in your Crossplane cluster:
Apply the function to your cluster:
Use the function in your Crossplane compositions to inject environment-specific configurations:
-dev
VariantFor debugging and development, use the -dev
variant which includes additional tools:
The function accepts configuration through its input specification. Key configuration options include:
Specify which environment configs to apply:
merge
: Merge environment config with existing valuesreplace
: Replace existing values with environment configThis image automatically uses FIPS 140-3 validated cryptographic modules. No additional configuration is required to enable FIPS mode, as it is built into the base system. This makes it suitable for environments requiring federal compliance standards such as FedRAMP.
If you encounter errors like "incompatible Crossplane version: package is not compatible with Crossplane version (): Invalid Semantic Version", this typically occurs when:
Using latest
tags: Crossplane requires semantic versioning for compatibility checks. Ensure your Crossplane deployment uses specific version tags (e.g., 2.0.2
) instead of latest
.
Version detection issues: If the error persists with proper version tags, you can bypass version constraints by adding ignoreCrossplaneConstraints: true
to your Function specification:
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:
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.
