docker容器日志大小设定

vim /etc/docker/daemon.json

{
  "registry-mirrors": ["http://f613ce8f.m.daocloud.io"],
  "log-driver":"json-file",
  "log-opts": {"max-size":"500m", "max-file":"3"}
}

单个容器编排

nginx: 
  image: nginx:1.18-alpine 
  restart: always 
  logging: 
    driver: "json-file"
    options: 
      max-size: "5g"
