Docker入门之基本命令

Mint下安装Docker

sudo apt-get install lxc-docker

Docker启动报错：

Error loading docker apparmor profile: exec: "/sbin/apparmor_parser"

须要安装依赖包

sudo apt-get install apparmor

运行Docker镜像

sudo docker run -i -t ubuntu /bin/bash

-i： 保证容器中STDIN开启

-t： 为容器分配一个伪tty终端

查看当前系统中容器的列表

docker ps -a

从新打开容器会话shell

sudo docker attach titus_docker_container

exit退出容器shell后，容器会随之中止运行。若需从新运行容器，须要执行

sudo docker start titus_docker_container sudo docker attach titus_docker_container

建立守护式容器，不打开shell会话，让进程打印hello world

huangyi@HP ~ % sudo docker run --name daemon_dave -d ubuntu /bin/sh -c "while true;do echo hello world; sleep 1; done"

查看daemon容器内部日志

sudo docker logs daemon_dave

查看daemon容器内部进程

sudo docker top daemon_dave

查看daemon容器更多信息

sudo docker inspect daemon_dave

查看daemon容器固定字段信息

sudo docker inspect --format='{{ .NetworkSettings.IPAddress }}' daemon_dave

docker工做目录位于/var/lib/docker/containers，目录树以下

在a6b*-json.log中能够查看daemon容器的日志

{"log":"hello world\n","stream":"stdout","time":"2015-10-11T11:39:26.038047014Z"}
{"log":"hello world\n","stream":"stdout","time":"2015-10-11T11:39:27.039658441Z"}
