Tired of wrangling dependencies to craft distroless containers from scratch? unbase_oci flips the script.

Instead of painstakingly building up from a minimal base, you start with a comfortable, fully-featured container—think debian or ubuntu—and develop as usual. Then, with one simple command, unbase_oci automatically strips your image down to the bare essentials by comparing it to the base and keeping only what’s truly needed.

No more trial-and-error to get your distroless image just right. Write normal Dockerfiles, enjoy all your debugging tools during dev, and let unbase_oci do the slimming for production.

It’s Bash. It’s fast. It’s minimal. It works with any OCI image and requires nothing but standard Unix tools and your container engine of choice.

Let’s stop over-engineering minimalism. Build smart, then unbase.
