docker 命令鸡脑壳就那么大还间歇性失忆，时间长不用就忘记了，先记下来吧，省得下次还要满世界找，嘿哈，不定时更新~

docker login -u 账号 -p 密码 登录 Docker 镜像仓库，默认是 Docker hub
docker info 显示 Docker 系统信息，包括镜像和容器数
docker history httpd --format "table {{.ID}}\t{{.CreatedBy}}" --no-trunc，通过docker history查看镜像构建过程（即dockerfile）

docker ps/top/stats，适合快速了解容器运行状态，从而判断是否需要进一步分析和排查
docker run -p 80:80 -d httpd
docker attach，可以attach到一个已经运行的容器的stdin
docker logs -f，能够打印出自容器启动以来完整的日志
