  "github_readme_excerpt": "# eatmemory\n\nA small command-line tool that allocates and **holds** a specified amount of\nRAM until you release it. One job, done reliably.\n\n```sh\neatmemory 1G\n```\n\n## Why eatmemory?\n\n- **Verified allocation.** Every byte is written and read back through\n  volatile-qualified pointers before the tool reports success. If\n  `eatmemory 1G` exits with status 0, you got 1 GB of *resident, committed*\n  memory. Not a lazy kernel reservation, not a write the compiler optimized\n  away.\n- **Portable.** Builds and runs on Linux (glibc and musl), macOS, Windows,\n  and AIX. CI exercises **44 cross-compile targets**, including m68k, mips,\n  ppc64le, riscv32/64, xtensa, and wasi, across **gcc 4 through gcc 13**.\n  If your platform has a C99 compiler, eatmemory likely works on it.\n- **Tiny, zero runtime dependencies.** A single C99 binary; no shared\n  libraries beyond libc. Static-link friendly.\n- **Docker-ready, multi-arch.** `docker run --rm julman99/eatmemory 1G`.\n  Especially useful for exercising memory behavior *inside* containers.\n- **Simple by design.** `eatmemory \u003csize\u003e`. For comparison:\n\n  ```sh\n  eatmemory 1G                                                    # eatmemory\n  stress-ng --vm 1 --vm-bytes 1G --vm-keep --vm-method zero-one   # alternative\n  ```\n\n## Use cases\n\n- **Test swap configuration.** Fill RAM, observe the system start paging.\n- **Test container memory limits.** Run inside `docker run --memory=512m`\n  and confirm the OOM-killer fires where you expect.\n- **Test Kubernetes pod limits, evictions, QoS classes, and HPA.** Deploy a\n  pod running `eatmemory 90%` and watch pod eviction, QoS-class behavior, or\n  horizontal-pod-autoscaler triggers.\n- **Validate monitoring and alerting.** Generate memory pressure on demand\n  to confirm your alerts fire on the right thresholds.\n- **Test service degradation under pressure.** Run alongside a real service\n  and watch tail latency as the system starves for memory.\n- **Test autoscaling.** Trigger memory-based scaling polic",
