Be my base image: Introducing Linky’s Matchmaker

Finding the right match isn’t always easy. Maybe it’s a crush you’ve been texting but suddenly leaves you on read, a pair of shoes that look perfect but you’re left limping the next day, or even the latest tech trend that just doesn’t click. Great matches often take a little time and a bit of persistence.

Modernizing container builds feels just like this: you know you want something safer and more reliable, but figuring out which base image to use (and how to update your Dockerfile without breaking everything) can be a time sink.

Meet Linky’s Matchmaker: Your Dockerfile’s new best friend

If containers had a dating show, this would be the episode where everything finally clicks. Linky’s Matchmaker is a web-based app that helps you convert Dockerfiles to use Chainguard Containers. Drop your Dockerfile in, and the app will analyze your current setup, recommend compatible Chainguard replacements, and generate a downloadable converted Dockerfile. You’ll also get handy links to available tags, documentation, and vulnerability comparisons.

No wrestling with endless base image options. No guesswork. Just a smoother path from “this is what we’re running” to “this is what we should be running.”

What the app does

The experience is intentionally straightforward:

• Upload your Dockerfile (or even a .txt file with Dockerfile content).

• The app uses DFC to analyze your current setup and to convert your Dockerfile to use Chainguard Containers.

• It suggests the best Chainguard alternatives for your current images, so you’re not left wondering which maps map to which.

• You get a downloadable, converted Dockerfile ready to try right away.

And because confidence matters, it also validates image availability and surfaces helpful links to documentation, image tags, and vulnerability comparisons.

Why Chainguard Containers are a better match

Most teams aren’t deliberately choosing insecure images. Developers end up choosing what works in fewer tries or what they are already familiar with.

Chainguard Containers are built for how we ship software today: minimal, secure by default, and designed to reduce the noise and risk that come from oversized, general-purpose images. That means fewer surprises, fewer vulnerabilities to chase down, and a more solid foundation for your workloads — without turning your day into a research project.

Ready to find your perfect match?

If you’ve been meaning to explore Chainguard Containers, or if your Dockerfiles have been due for a glow-up, Linky’s Matchmaker is a friendly place to start. Upload your Dockerfile, see what Chainguard recommends, and walk away with a converted version you can test immediately.

Because when it comes to base images, you don’t have to settle. With Chainguard’s minimal, secure containers (hello, zero CVEs!) and a matchmaker that makes the switch feel effortless, you can spend less time chasing build drama and more time shipping what you actually care about. Give Linky’s Matchmaker a spin, and find the kind of container match that’s built to last.
