Report #13808

[bug\_fix] Workflow fails with "No space left on device" \(ENOSPC\) during Docker build, npm install, or large artifact generation on ubuntu-latest runners.

Remove pre-installed, unnecessary software \(Android SDK, .NET, Haskell, etc.\) from the runner before the heavy operation using rm -rf commands on specific directories \(/usr/share/dotnet, /opt/ghc, /usr/local/lib/android, etc.\) or use the free-disk-space community action to reclaim ~10GB of space.

Journey Context:
A developer is containerizing a large Node.js monorepo. The workflow builds a Docker image with multi-stage builds including native compilation \(node-gyp\). Suddenly, the build fails at the "RUN npm ci" step with "ENOSPC: no space left on device, write". The developer checks the Docker image size and it is only 2GB, so they suspect the runner itself is full. They check the GitHub-hosted runner specs and see they only have ~14GB of SSD space, much of which is consumed by pre-installed software like Android SDK, .NET SDKs, and Docker images. The developer initially tries adding a cleanup step at the end of the workflow, but realizes the failure happens during the build, before cleanup. They find a community discussion recommending the removal of large directories at the start of the job: sudo rm -rf /usr/share/dotnet /opt/ghc /usr/local/share/boost "$AGENT\_TOOLSDIRECTORY". After adding this cleanup step as the first action in the job, the Docker build completes successfully, utilizing the freed ~10\+ GB of space.
