FIPS 140-3 Certification

This image is FIPS-validated to ensure its cryptographic operations meet the Federal Information Processing Standards (FIPS) required for secure government and regulated environments. Its core cryptographic modules are validated under the NIST Cryptographic Module Validation Program (CMVP) and comply with the FIPS 140-3 standard.

To verify that the FIPS 140-3 provider is configured and used in the image, follow the instructions for the OpenSSL FIPS module in the FIPS compliance tab.

Go-FIPS includes a proprietary minimus-cryptographic-module and openssl-fips-config that enforce FIPS mode, without the ability to opt out. Go-FIPS does not use native golang cryptographic functionality. Instead crypto-related packages are patched to redirect all calls to the OpenSSL FIPS provider. The Go-FIPS image is built using the new microsoft/go toolchain (First published January 2026; This replaces the previous source from golang-fips/go project)

Try It Out

Apps built with Go-FIPS also require an OpenSSL FIPS module which is provided by the Glibc-Dynamic-FIPS runtime image from Minimus. In this example, we build a simple web application with Go-FIPS and the Glibc-Dynamic-FIPS runtime image.

In a new project directory, save the code below to a new Dockerfile:

# Pull Go-FIPS image and set it as builder
FROM reg.mini.dev/go-fips AS builder

ENV GOOS=linux GOARCH=amd64

# Copy the project directory content to app directory in the container
COPY . /app

# Compile Go application
RUN cd /app && go build -o Hello-Minimus-Web .

# Pull dynamic image to use as a runtime base
FROM reg.mini.dev/glibc-dynamic-fips:latest

# Copy Go binary from the /app directory in the builder container to /usr/bin/ in the final dynamic container
COPY --from=builder /app/Hello-Minimus-Web /usr/bin/

EXPOSE 8080

# Set entrypoint to run the binary when the container is started
ENTRYPOINT ["/usr/bin/Hello-Minimus-Web"]

This example builds a dynamic Go application, meaning it is linked to database drivers or other C integrations. The CGO_ENABLED=1 flag is not needed in the Dockerfile because it is already enabled by default. The CGO_ENABLED=1 flag is responsible for compiling the Go code using dynamically linked binaries.

Download the example file hello-minimus-web.go and save it to your project directory. This is a very simple script that creates a webpage with several tabs so you can navigate between them.

In your project directory, create a go.mod file. This file declares the modules and dependencies required by the project. In our case, the module set is only needed for testing purposes, so it's very simple.

module minimus.dev/hello_minimus

go 1.25

Your project directory should now look like this:

project-root/
├── Dockerfile
├── hello-minimus-web.go
└── go.mod

From your project directory, build your custom image. Note that the period . specifies the current directory as the build context:

docker build -t hello-go-web .

Run the final image we just created:

docker run -p 8080:8080 hello-go-web

Open your browser and go to http://localhost:8080/ to see the default welcome page.

Technical Considerations

The Go-FIPS image provided by Minimus is a slim, security-hardened alternative to the public image from Docker Hub. The images are largely interchangeable, with a few differences as noted below.
