Docker CPU 부하 테스트

spawn N workers spinning on sqrt()

CPU 부하

docker run --name stress --rm -it progrium/stress --timeout 20s --cpu 1

모니터링

# 실시간으로 확인하면서 stats.txt 에도 기록
docker stats --format "table {{.Name}}\t{{.CPUPerc}}\t{{.MemUsage}}" | tee stats.txt

# 최대치 3건 조회
cat stats.txt | grep stress | sort -V | tail -3
