docker命令文档

1、帮助命令

docker version # 显示docker的基本信息
docker info # 系统信息，镜像和容器的数量
docker 命令 --help # 全部信息

2、镜像命令

命令	作用
docker images	查看所有本地主机上的镜像
docker search	搜索仓库中的镜像，相当于网页搜索
docker pull	下载镜像
docker rmi	删除镜像

2.1、docker images

查看所有本地主机上的镜像

[root@localhost ~]# docker images

在这里插入图片描述

Options:
  -a, --all             Show all images (default hides intermediate images)
      --digests         Show digests
  -f, --filter filter   Filter output based on conditions provided
      --format string   Pretty-print images using a Go template
      --no-trunc        Don't truncate output
  -q, --quiet           Only show numeric IDs

2.2、 docker search

搜索仓库中的镜像，相当于网页搜索

docker hup

在这里插入图片描述

docker search mysql

在这里插入图片描述

2.3、 docker pull

下载镜像

docker pull mysql # 下载mysql镜像，default tag，默认最新版latest

在这里插入图片描述

下载指定版本

先在docker hup上搜索mysql

docker pull mysql:5.7

在这里插入图片描述

docker images

此时查看镜像，可以看到新下载的两个

2.4、 docker rmi

删除经镜像

docker rmi -f 镜像id
# 删除多个 用空格分隔id
docker rmi -f id id id
# 删除所有 
docker rmi -f $(docker images -aq) # images -aq就是查所有镜像id，从而递归删除

3、容器命令

docker pull centos

3.1、新建容器并启动

docker run [可选参数] image

# 参数说明
--name=“Name” # 容器名字，用于区分容器
-d 后台方式运行
-it 使用交互方式运行，进入容器查看内容
-p 指定容器的端口 如-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 随机指定端口

# 进入
docker run -it centos /bin/bash 
# 查看目录
ls
# 退出
exit

在这里插入图片描述

主机名不一样

3.2、查看运行的容器

# 查看正在运行的容器
docker ps
# 查看曾经运行的容器
docker ps -a
# 显示最近创建的容器，设置显示个数
docker ps -a - n=? 
# 只显示容器的编号
docker ps -aq

在这里插入图片描述

3.3、退出容器

# 容器停止退出
exit
# 容器不停止退出 注意必须在英文输入法下，中文输入法不行
Ctrl + P + Q

[root@localhost ~]# docker run -it centos /bin/bash
[root@c977bd6638aa /]# [root@localhost ~]# docker ps  ## 这里Ctrl + P + Q
CONTAINER ID        IMAGE               COMMAND             CREATED              STATUS              PORTS               NAMES
c977bd6638aa        centos              "/bin/bash"         About a minute ago   Up About a minute                       zealous_boyd
[root@localhost ~]# docker exec -it c977bd6638aa /bin/bash ## 再次进入
[root@c977bd6638aa /]# exit ##停止并推出
exit
[root@localhost ~]#

3.4、删除容器

# 删除指定容器 不能删除正在运行的容器，如果强制删除 rm -f
docker rm 容器id
# 删除所有容器
docker rm -f $(docker ps -aq)
# 删除所有容器
docker ps -a -q|xargs docker rm

[root@localhost ~]# docker ps -a
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS                      PORTS               NAMES

[root@localhost ~]# docker rm 273aaf03a722
273aaf03a722
[root@localhost ~]# docker rm c977bd6638aa  ##不能删除正在运行的容器
Error response from daemon: You cannot remove a running container c977bd6638aad432f29b42dfce4f8dfaed924fdd2fa268c6e2888c9d4bdb2930. Stop the container before attempting removal or force remove
[root@localhost ~]#

删除全部容器

4、查看日志

docker logs
docker logs -f -t --tail n 【容器id】

[root@localhost ~]# docker logs --help

Usage:  docker logs [OPTIONS] CONTAINER

Fetch the logs of a container

Options:
      --details        Show extra details provided to logs
  -f, --follow         Follow log output
      --since string   Show logs since timestamp (e.g. 2013-01-02T13:23:37) or relative (e.g. 42m for 42 minutes)
      --tail string    Number of lines to show from the end of the logs (default "all")
  -t, --timestamps     Show timestamps
      --until string   Show logs before a timestamp (e.g. 2013-01-02T13:23:37) or relative (e.g. 42m for 42 minutes)
[root@localhost ~]#

# 运行一个centos
[root@localhost ~]# docker run -it centos /bin/bash
[root@d4e5c988112e /]# [root@localhost ~]# docker ps

# 停止正在疯狂输出的那个容器
[root@localhost ~]# docker stop 77f7f6ce6f3b
77f7f6ce6f3b

6、进入当前正在运行的容器

6.1、docker exec -it 容器id bashSHELL

# 我们通常容器都是使用后台方式运行的
[root@localhost ~]# docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES
d4e5c988112e        centos              "/bin/bash"         31 minutes ago      Up 31 minutes                           laughing_nobel
[root@localhost ~]# docker exec -it d4e5c988112e /bin/bash
[root@d4e5c988112e /]# ls
bin  dev  etc  home  lib  lib64  lost+found  media  mnt  opt  proc  root  run  sbin  srv  sys  tmp  usr  var
[root@d4e5c988112e /]# ps -ef
UID         PID   PPID  C STIME TTY          TIME CMD
root          1      0  0 07:38 pts/0    00:00:00 /bin/bash
root         14      0  0 08:11 pts/1    00:00:00 /bin/bash
root         28     14  0 08:12 pts/1    00:00:00 ps -ef
[root@d4e5c988112e /]# exit
exit
[root@localhost ~]# docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES
d4e5c988112e        centos              "/bin/bash"         33 minutes ago      Up 33 minutes                           laughing_nobel
[root@localhost ~]#

6.2、docker attach 容器id

[root@localhost ~]# docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES
d4e5c988112e        centos              "/bin/bash"         33 minutes ago      Up 33 minutes                           laughing_nobel
[root@localhost ~]# docker attach d4e5c988112e
[root@d4e5c988112e /]#

区别：

docker exec :进入容器后开启一个新的终端，可以在里面操作(常用)

docker attach:进入容器正在执行的终端，不会启动新的进程

7、从容器内拷贝文件到主机上

# 运行
[root@localhost ~]# docker run -it centos
# ctrl P Q 不关闭退出，查看
[root@10440710b9f4 /]# [root@localhost ~]# cd /home
# 查看主机home下无文件 test.java文件
