一、 镜像类指令：
1. 查询镜像
[root@localhost ~]# docker search nginx NAME DESCRIPTION STARS OFFICIAL AUTOMATED nginx Official build of Nginx. 13423 [OK] jwilder/nginx-proxy Automated Nginx reverse proxy for docker con… 1832 [OK] richarvey/nginx-php-fpm Container running Nginx + PHP-FPM capable of… 780 [OK] linuxserver/nginx An Nginx container, brought to you by LinuxS… 118 ...省略
2. 下载镜像到本地
[root@localhost ~]# docker pull busybox #没指明标签就是下载latest Using default tag: latest latest: Pulling from library/busybox 91f30d776fb2: Pull complete Digest: sha256:9ddee63a712cea977267342e8750ecbc60d3aab25f04ceacfa795e6fce341793 Status: Downloaded newer image for busybox:latest docker.io/library/busybox:latest
3. 查看本地当前已有镜像
[root@localhost ~]# docker image ls #也可以使用docker images REPOSITORY TAG IMAGE ID CREATED SIZE busybox latest c7c37e472d31 5 days ago 1.22MB
4. 显示本地当前已有镜像IMAGE ID的全名
[root@localhost ~]# docker image ls --no-trunc #也可以使用docker images --no-trunc REPOSITORY TAG IMAGE ID CREATED SIZE busybox latest sha256:c7c37e472d31c1685b48f7004fd6a64361c95965587a951692c5f298c6685998 5 days ago 1.22MB
5. 查看基于此镜像制作容器启动时默认运行的命令
6. 删除镜像
[root@localhost ~]# docker image rm busybox #也可以使用docker rmi busybox

[root@localhost ~]# docker image ls
REPOSITORY TAG IMAGE ID CREATED SIZE
二、 容器类指令
1. 创建容器并运行进入交互模式
[root@localhost ~]# docker container run --name b1 -it busybox #也可以使用docker run --name b1 -it busybox WARNING: IPv4 forwarding is disabled. Networking will not work. / #
2. 查看当前运行的容器
[root@localhost ~]# docker container ls #也可以使用docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 0ff1821efedd busybox "sh" About a minute ago Up About a minute b1
3. 查看没有在运行的容器
[root@localhost ~]# docker container run --name b1 -it busybox WARNING: IPv4 forwarding is disabled. Networking will not work. / # exit #退出容器，容器运行就停止了 [root@localhost ~]# docker container ls -a #要加-a才可以看到没有运行的容器；也可以使用docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 0ff1821efedd busybox "sh" 2 minutes ago Exited (0) 6 seconds ago b1
4. 启动容器并进入交互模式
[root@localhost ~]# docker container start -ia b1 #这里要注意，加-ia是启动容器并执行创建时的指令，所以如果创建时没加-it，则这里不会进交互模式 / #
5. 创建容器运行在后台，并运行httpd
[root@localhost ~]# docker container run --name b2 -d busybox httpd -f #-d表是容器运行在后台；httpd必须加-f表示httpd运行在前台，否则容器会认为没有运行进程 WARNING: IPv4 forwarding is disabled. Networking will not work. eac9f80ff2f54a691913d82f11723e34cc05bcbc03d2c3bbce92c90eeb59e5bc [root@localhost ~]# docker container ls #没有加-a表示只看的到运行中的容器 CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES eac9f80ff2f5 busybox "httpd -f" 3 seconds ago Up 3 seconds b2
6. 绕过容器边界，让容器进入交互模式
[root@localhost ~]# docker container exec -it b2 /bin/sh / #
6. 停止容器
[root@localhost ~]# docker container stop b2 #也可以使用docker container kill b2，这样是强制停止，尽量不要使用强制停止，否则可能会有资料的遗失 b2 [root@localhost ~]# docker container ls -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES eac9f80ff2f5 busybox "httpd -f" 5 minutes ago Exited (137) 5 seconds ago b2 0ff1821efedd busybox "sh" 20 minutes ago Exited (137) 26 seconds ago b1
7. 删除容器
[root@localhost ~]# docker container rm b1 b2 b1 b2 [root@localhost ~]# docker container ls -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
