*  查看docker容器日志

docker logs ${container}

*  启动容器

#gpuid='2'
    #container=hzhj_tmp
    #imgname=ubuntu:latest
    gpuid=$1
    container=$2
    imgname=$3
    
    NV_GPU=${gpuid} nvidia-docker run -u root -it --name=${container} -v /etc/localtime:/etc/localtime:ro -v /data1/:/workspace/mydata/user ${imgname} /bin/bash

*  gpu环境

sudo docker run -u root --runtime=nvidia

*  退出容器

container=$1
    docker stop ${container} && docker rm ${container}

*  删除无用容器

docker rm $(docker ps -q -f status=exited)
    docker volume rm $(docker volume ls -qf dangling=true)
    docker rmi $(docker images --filter "dangling=true" -q --no-trunc)
    docker images -a|grep none|awk '{print $3 }'|xargs docker rmi
    
    
    #大招
    docker system prune

*  [https://hub.docker.com/][https_hub.docker.com]登录

docker login --username=${name}--password ${password}

*  [镜像重命名][Link 1]

docker image tag server:latest myname/server:latest
    
    docker image tag d583c3ac45fd myname/server:latest
    
    docker tag d583c3ac45fd myname/server:latest

*  容器内存查看

docker stats --no-stream|grep python

*  容器dns查询

cat /etc/resolv.conf

*  CentOS宿主机根据pid获得容器id

cat /proc/${PID}/cgroup   #获得容器id
    docker inspect --format '{
       {.Name}}' "${containerId}" | sed 's/^\///'  #根据完整容器id获得容器name
    
    docker ps |grep ${part_containerId}*    #根据容器id前部分加上通配符获得容器信息
