Overview

Command example demonstrates and verifies the end-to-end effect of memlimit: it applies GOMEMLIMIT from the cgroup, then reads the runtime's current value back via debug.SetMemoryLimit(-1) to confirm it was actually applied.

# no limit -> no-op, GOMEMLIMIT stays at the default (max int64)
go run .

# real 256 MiB limit -> GOMEMLIMIT set to 90% (241591910)
docker run --rm --memory=256m -v <project>:/work \
