镜像（image）

容器(container) 启动，删除，停止

仓库(repository)

docker images

docker images -a 列出全部

docker images -q 只显示镜像id

docker search 搜索镜像

搜索收藏大于3000的… docker search mysql -f=STARS=3000

docker pull 下载镜像

如果不写tag默认就是latest，下载是分层下载

删除镜像 docker rmi 镜像

新建容器并启动：

docker run

参数:

--name="name" 容器名称 tomcat1 tomcat2 区分容器

-d 后台方式运行

-it 使用交互方式运行，进入容器内部查看内容

-p 指定容器端口 -p 8080:8080

-p ip:主机端口:容器端口

-p 主机端口:容器端口

-p 容器端口

-p (不指定端口就随机端口了啊)

比如这个就是启动并且进入容器内部

docker run -it centos /bin/bash

退出容器:exit(退出就停止了)

xtel+P+Q 不停止退出

查看正在运行的容器docker ps

docker ps -a -n=1 列出正在运行的容器+历史运行过容器

-n 最近创建的容器

docker ps -aq {-q}显示容器编号

删除容器:

docker rm 容器id 删除指定容器正在运行则删除失败

docker rm -f 删除所有容器

docker ps -a -q |xargs docker rm 删除所有容器

启动和停止的容器操作

docker start 容器id

docker restart 容器id

docker stop 容器id

docker kill 容器id

后台启动容器后-d

发现容器停止了，容器后台启动必须有后台进程，发现没有后台进程会自动停止

编写shell脚本输出日志

docker run -d centos /bin/sh -c "while true;do echo kuang;sleep 1;done"

查看日志 docker logs -tf --tail 10 d1c5d0984801

备注：

-tf 显示日志

--tail 【number】显示日志条数

显示容器进程信息

docker top 容器id

查看镜像元数据

docker inspect d1c5d0984801

进入容器的两种方式：

docker attach 容器id 进入正在执行的容器，不会启动新终端。

docker exec 进入容器后开启一个新的终端.

从容器内拷贝文件到主机上

docker cp 容器id 容器内路径目的主机路径

数据从容器内部拷出到win10： docker cp bc81713669cf:/var/log F:/docker_data/lib

数据将从win10 拷进 docker

docker cp F:/docker_data/newdata bc81713669cf:/home

小总结：

attach:当前shell下attach连接指定运行镜像

build:通过dockerfile定制镜像

commit:提交当前容器作为新的镜像

cp:从容器中拷贝指定文件或目录到宿主机器中

create:创建一个新容纳国企但不启动容器

diff:查看docker容器变化

events：从docker服务获取容器实时事件

exec:进入已存在的容器，不启动新窗口

export:导出容器的内容流作为一个tar归档文件[对应imoprt]

history：展示一个镜像形成历史

images:列出系统当前镜像

import:从tar包中的内容创建一个新的文件系统

info:展示系统相关信息

inspect:查看容器详细信息

kill：杀死指定kill容器

load:从一个tar包中加载一个镜像

logs:输出日志信息

logout:退出

port:查看映射端口对应的容器内部源端

pause:暂停容器

ps:列出容器列表

pull:从源拉取指定镜像

push:推送指定镜像

restart:从其运行的容器

rm：移除容器

rmi：移除镜像

run :创建一个新容器并启动

save:保存镜像

search:搜索镜像

start:启动镜像

stop:停止镜像

tag:给镜像打标签

top:查看镜像进程

unpause:取消暂停镜像

version:看版本

wait：截取容器停止时的退出状态值
