From 5bd42c84440c6ea3b274e2032882526cfafe8b7a Mon Sep 17 00:00:00 2001 From: konard Date: Fri, 13 Feb 2026 20:37:52 +0100 Subject: [PATCH 2/3] Fix disk space exhaustion in Docker image publishing (Issue #41) Added jlumbroso/free-disk-space action to docker-build-push and docker-build-push-arm64 jobs to prevent "No space left on device" errors. This frees approximately 30 GB by removing unused pre-installed software (Android SDK, .NET runtime, large packages). Changes: - Add disk space cleanup step before Docker builds in release workflow - Add case study documentation with root cause analysis and solutions - Add changeset for automatic version bump Root cause: The workflow failed because GitHub Actions runners ran out of disk space when building the full sandbox Docker image. The runner starts with ~22 GB free space (ubuntu-24.04 x64) but pre-installed software occupies significant space.
