This docker image is solely for the purpose of creating the image that runs for Zig's Drone CI script.
Zig makes Docker irrelevant. You probably do not need a Docker image to build your Zig application, and you definitely do not need this one.
First, decide whether to bump the base alpine image version. Next:
docker build -t ziglang/static-base:llvm15-$(uname -m)-1 . --build-arg ZIGVER=0.10.0-dev.4560+828735ac0
docker push ziglang/static-base:llvm15-$(uname -m)-1
