  -H, --host list          Daemon socket(s) to connect to
  -l, --log-level string   Set the logging level ("debug"|"info"|"warn"|"error"|"fatal") (default "info")
      --tls                Use TLS; implied by --tlsverify
      --tlscacert string   Trust certs signed only by this CA (default "/root/.docker/ca.pem")
      --tlscert string     Path to TLS certificate file (default "/root/.docker/cert.pem")
      --tlskey string      Path to TLS key file (default "/root/.docker/key.pem")
      --tlsverify          Use TLS and verify the remote
  -v, --version            Print version information and quit

Management Commands:
  config      Manage Docker configs
  container   Manage containers
  image       Manage images
  network     Manage networks
  node        Manage Swarm nodes
  plugin      Manage plugins
  secret      Manage Docker secrets
  service     Manage services
  stack       Manage Docker stacks
  swarm       Manage Swarm
  system      Manage Docker
  trust       Manage trust on Docker images
  volume      Manage volumes

2.启动、关闭、重启docker

//命令 systemctl start docker(启动docker)
[root@localhost ~]# systemctl start docker
//命令 systemctl stop docker(关闭docker)
[root@localhost ~]# systemctl stop docker
//命令 systemctl restart docker(重启docker)
[root@localhost ~]# systemctl restart docker
//命令 systemctl enable docker(设置docker随服务启动而自启动)
[root@localhost ~]# systemctl enable docker
Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.

3.查看

//命令  docker version
//查看docker的版本号
[root@localhost ~]# docker version

3.下载镜像

注意：我们下载的镜像必须是在仓库中能查找到的！！！可以先登录仓库网址查询要下载的镜像及版本。docker仓库官网：https://hub.docker.com/

比如进docker仓库查询一下mysql的镜像及版本：

拉取镜像：

命令：docker pull 镜像名（默认是最新版的）

docker pull 镜像名:tag（拉取指定版本的镜像）

//从仓库拉取mysql镜像
[root@localhost ~]# docker pull mysql:latest
latest: Pulling from library/mysql
0bb5c0c24818: Pull complete 
cbb3106fbb5a: Pull complete 
550536ae1d5e: Pull complete

Status: Downloaded newer image for mysql:latest

4.运行镜像并生成容器

//命令 docker run 镜像名:tag /bin/bash
//-it表示以交互式运行
[root@localhost ~]# docker run -it mysql:latest /bin/bash
bash-4.4# 
//使用Ctrl+P+Q退出容器，用docker ps查看刚才运行的容器
bash-4.4# [root@localhost ~]# docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                 NAMES
115c9b4f1e0e        mysql:latest        "docker-entrypoint.s…"   2 minutes ago       Up 2 minutes        3306/tcp, 33060/tcp   sharp_easley

5.删除镜像

//使用docker images查看已有的镜像
[root@localhost ~]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE

hello-world         latest              feb5d9fea6a5        14 months ago       13.3kB
centos              latest              5d0da3dc9764        14 months ago       231MB
//命令 docker rmi -f 镜像id（删除某一个镜像，删除多个的话镜像id中间用空格）
//删除mysql镜像
[root@localhost ~]# docker rmi -f 3842e9cdffd2

三、docker的容器命令

1.查看容器

//命令 docker ps（查看正在运行的容器）
[root@localhost ~]# docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                 NAMES
16c1136241dd        mysql               "docker-entrypoint.s…"   2 minutes ago       Up 2 minutes        3306/tcp, 33060/tcp   upbeat_blackwell
//命令 docker ps -a（查看所有的容器，包括正在运行和已经停止的）
[root@localhost ~]# docker ps -a
CONTAINER ID        IMAGE               COMMAND                  CREATED              STATUS                      PORTS                 NAMES
c70259707a44        centos              "/bin/bash"              About a minute ago   Exited (0) 15 seconds ago                         objective_saha
16c1136241dd        mysql               "docker-entrypoint.s…"   2 minutes ago        Up 2 minutes                3306/tcp, 33060/tcp   upbeat_blackwell

2.运行容器

//命令 docker run -it -d --name 要取的别名 镜像名:tag /bin/bash
//-it 表示与容器进行交互式启动
//-d表示可后台运行容器
//--name给要运行的容器取的名
//以交互式启动mysql容器
[root@localhost ~]# docker run -it mysql /bin/bash
bash-4.4# [root@localhost ~]# 
//以交互式启动centos容器
[root@localhost ~]# docker run -it centos /bin/bash
[root@b56d0be965aa /]# [root@localhost ~]# 
[root@localhost ~]# 
//查看当前正在运行的容器
[root@localhost ~]# docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED              STATUS              PORTS                 NAMES
b56d0be965aa        centos              "/bin/bash"              30 seconds ago       Up 28 seconds                             reverent_williams
26b580adce05        mysql               "docker-entrypoint.s…"   About a minute ago   Up About a minute   3306/tcp, 33060/tcp   jovial_johnson
16c1136241dd        mysql               "docker-entrypoint.s…"   11 minutes ago       Up 11 minutes       3306/tcp, 33060/tcp   upbeat_blackwell
//命令 docker exec -it 容器id /bin/bash（以交互式进入当前正在运行的容器）
[root@localhost ~]# docker exec -it b56d0be965aa /bin/bash
[root@b56d0be965aa /]# 
[root@b56d0be965aa /]# read escape sequence
//命令 docker attach 容器id（进入当前正在运行的容器）
[root@localhost ~]# docker attach b56d0be965aa
[root@b56d0be965aa /]# ls
bin  dev  etc  home  lib  lib64  lost+found  media  mnt  opt  proc  root  run  sbin  srv  sys  tmp  usr  var
//exit停止容器并且退出
[root@b56d0be965aa /]# exit
exit
[root@localhost ~]#

3.进入容器

有两种方式：①docker exec -it 容器id /bin/bash（进入正在运行的容器后悔开启一个新的终端，常用）；②docker attach 容器id（进入容器后直接进行正在执行的终端，不会开启新的终端）

//命令 docker exec -it 容器id /bin/bash（以交互式进入当前正在运行的容器）
[root@localhost ~]# docker exec -it b56d0be965aa /bin/bash
[root@b56d0be965aa /]# 
[root@b56d0be965aa /]# read escape sequence
//命令 docker attach 容器id（进入当前正在运行的容器）
[root@localhost ~]# docker attach b56d0be965aa
[root@b56d0be965aa /]# ls
bin  dev  etc  home  lib  lib64  lost+found  media  mnt  opt  proc  root  run  sbin  srv  sys  tmp  usr  var

4.退出容器

也有两种方式：①exit,这种方式会直接将当前运行的容器停止掉退出；②Ctrl+P+Q，这种不停止当前的容器进行退出。

[root@localhost ~]# docker exec -it 26b580adce05 /bin/bash
//使用exit退出，直接容器停止并且退出
bash-4.4# exit
exit
[root@localhost ~]# 
[root@localhost ~]# docker exec -it 26b580adce05 /bin/bash
//使用Ctrl+P+Q容器不停止退出
bash-4.4# read escape sequence
[root@localhost ~]#

5.删除容器

//查看所有的容器
[root@localhost ~]# docker ps -a

[root@localhost ~]# docker run -d centos
917388d45cea522f4e63a48c080cda2d394c148ad4b770f364b43e81f21dd8ea

2.查看日志

//命令 docker logs -tf --tail num 容器id
//-tf 表示显示日志
//--tail num 表示显示日志的条数
//查看id为917388d45cea容器的10条日志
[root@localhost ~]# docker logs -tf --tail 10 917388d45cea

3.查看容器中的进程信息

//命令 docker top 容器id

5.从容器中拷贝文件到宿主机

//进入centos容器
[root@localhost ~]# docker run -it centos /bin/bash
[root@aa63b6c1dc9d /]# ls
bin  dev  etc  home  lib  lib64  lost+found  media  mnt  opt  proc  root  run  sbin  srv  sys  tmp  usr  var
//在centos容器的home目录下创建一个zhangsan.java文件
[root@aa63b6c1dc9d /]# cd home
[root@aa63b6c1dc9d home]# touch zhangsan.java
[root@aa63b6c1dc9d home]# ls
zhangsan.java
[root@aa63b6c1dc9d home]# [root@localhost ~]# 
//命令 docker cp 容器id:容器内路径 宿主机的保存路径
//将id为aa63b6c1dc9d容器中的home下的zhangsan.java文件拷贝到宿主机的/home中
[root@localhost ~]# docker cp aa63b6c1dc9d:/home/zhangsan.java /home
[root@localhost ~]# cd /
[root@localhost /]# ls
bin  boot  dev  etc  home  lib  lib64  media  mnt  opt  proc  root  run  sbin  srv  sys  tmp  usr  var
[root@localhost /]# cd home
[root@localhost home]# ls
test.java  zhangsan.java

docker的命令还有很多，以上是最基本的，一起努力！！！
