docker

基础命令

docker run -it --name XXX centos:latest  # 运行容器镜像
docker ps [-a]  # -a可查询所有实例，包括已停止的
docker start ID  # 启动停止的容器实例
docker attach ID  # 使用最近的bash流，进入容器
docker exec -t ID /bin/bash  # 新建bash流，进入容器
docker cp LOCAL_PATH ID:/DOCKER_PATH
docker cp ID:/DOCKER_PATH LOCAL_PATH
exit  # 停止并退出容器

高级命令

When you kill and remove a Docker container, you're supposed to include the -v param in docker rm, but if you don't do that, the stuff in the volume will presist in the host's filesystem until you rm -rf form /var/lib/docker/volumes/, which can be dangerous if you're not careful.

docker rm -v $(docker ps -q -f status=exited)

清理损坏的或半成品镜像

docker rmi $(docker images -q -f dangling=true)

清理残留的volume

docker volume rm $(docker volume ls -qf dangling=true)

批量启动停止的容器

docker start $(docker ps -q -f status=exited)

拷贝主机目录或文件到容器内。如果files文件夹不存在，则将前者里的所有内容移入files，否则前者移入files

docker cp /root/amazeui-2.5.1/ CONTAINER:/var/www/files 

查看容器特定属性

docker inspect --format='{{ .NetworkSettings.IPAddress }}' CONTAINER

查看容器日志

# Show logs since timestamp
$ docker logs --since=2016-03-04T12:00:00 CONTAINER
# Number of lines to show from the end of the logs
$ docker logs --tail=30 CONTAINER

windows平台docker-machine对应的主机和密码docker@192.168.99.100 tcuser

linux远程文件传输命令，有git bash的windows也支持

scp -r amazeui-2.5.1/ root@liteapi.com:/root/

查看内存占用cat /proc/meminfo
