Why does Docker build run out of disk?
Quick answer
GitHub-hosted runners have around 14 GB free, which large images and their layer cache exhaust quickly.
The detail that matters
Prune between steps, or use a runner with a larger NVMe scratch disk.
Your next build could be twice as fast, at half the price
