Docker CPU 부하 테스트

CPU 부하

docker run -it --name cpustress --rm containerstack/cpustress --metrics-brief --timeout 20s --cpu 1

모니터링

docker stats --format "table {{.Name}}\t{{.CPUPerc}}\t{{.MemUsage}}" | tee stats.txt

→ 실시간으로 확인하면서 stats.txt 에도 기록

cat stats.txt | grep cpustress | sort -V | tail -3

→ 최대치 3건을 조회
