Static Overview

Secure your stack with a hardened static image freshly-built by Minimus. Minimus images always include the most up-to-date package version for all packages and dependencies.

Use this image in Dockerfile as a secure runtime base for self-contained, static binaries. For example, you can use this static image to run a compiled Go (Golang) binary, and build the most secure, vulnerability-free application possible. Learn how it's done

Try It Out

Before we can take the Minimus static image for a test run, we'll need a static binary to run. If you have a static binary ready on hand, you can skip the next step. Otherwise, download an example and compile the code:

gcc hello.c -o staticbin --static

If you want to first check that your file is in fact static, run ldd staticbin (where staticbin is simply the program name). You should see the message: "not a dynamic executable".

Now you are ready to build a minimal, secure image using the Minimus static image. Save this Dockerfile to your directory:

FROM reg.mini.dev/static

# Set the user to 1000 (or any other UID/GID from your base image)
USER 1000:1000

# Set the working directory inside the container
WORKDIR /app

# Copy the static binary into the image
COPY staticbin /app/staticbin

# Set the default command to run the binary
CMD ["/app/staticbin"]

It's important to explicitly set the user directive in the Dockerfile. Otherwise, Docker resets to the default user (root) and the base image's user will not be inherited.

Next, build your custom image and run it. Note that the period . specifies the current directory as the build context:

docker build -t minimus-static-image .
docker run --rm minimus-static-image

You should see the message: "Minimus says hello world"

Technical Considerations

The static image provided by Minimus is a hardened alternative to the scratch image from Docker Hub. The images are largely interchangeable, with a few differences as noted below.

Static built by Minimus:

The image can be used as a minimal, secure runtime base for any static, self-contained binary.
Static only comes in one version - latest.
Runs as non-root by default as user 1000. You'll need to explicitly set the USER directive in the Dockerfile for the final image to run as non-root.

The Payoff

A hardened, minimal image that will remain more secure for the long run and accrue vulnerabilities at a slower rate.
