docker详细
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
login:登录docker服务账号
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
