 If you don't care about the size, you can just build your Docker image on top of this one:

 But you probably want to use multistage build to minimize the final image, and it's a bit tricky. You need to take care of the following:
 
-1. Copy built dependencies from `/usr/local/lib`.
-2. Install ca-certificates, libsm6, liblzma5, libzstd1, and libpcre3 from the Debian repo.
-3. Set proper libraries paths.
+1. Copy built dependencies from `/opt/imgproxy`.
+2. Install required system dependencies.
 
 Here is the working example:
