?1.拉取一个镜像

实例:

[root@liuxin ~]# docker pull mysql:latest
latest: Pulling from library/mysql
8559a31e96f4: Already exists 
d51ce1c2e575: Pull complete 
c2344adc4858: Pull complete

Status: Downloaded newer image for mysql:latest
[root@liuxin ~]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
mysql               latest              6e447ce4863d        47 hours ago        544MB
nginx               latest              0901fa9da894        5 days ago          132MB
tomcat              latest              6055d4d564e1        9 days ago          647MB
tomcat              9-jre8              e24825d32965        14 months ago       464MB

?2. 在docker里启动一个镜像

命令

[root@liuxin ~]# docker run -it --rm \
> ubuntu:latest \
> bash

实例

[root@liuxin ~]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
mysql               latest              6e447ce4863d        47 hours ago        544MB
nginx               latest              0901fa9da894        5 days ago          132MB
ubuntu              latest              adafef2e596e        9 days ago          73.9MB
tomcat              latest              6055d4d564e1        9 days ago          647MB

[root@liuxin ~]# docker run -it --rm \
> ubuntu:latest \
> bash
root@cbe63b114858:/# ls
bin  boot  dev  etc  home  lib  lib32  lib64  libx32  media  mnt  opt  proc  root  run  sbin  srv  sys  tmp  usr  var

?3.查看所有的镜像列表

命令:docker images

[root@liuxin ~]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
mysql               latest              6e447ce4863d        47 hours ago        544MB
nginx               latest              0901fa9da894        5 days ago          132MB
tomcat              latest              6055d4d564e1        9 days ago          647MB
tomcat              9-jre8              e24825d32965        14 months ago       464MB

?4.删除镜像

1)方式一:docker image rm j镜像名:版本号

2)方式二:docker rmi 镜像ID

?5.删除全部image镜像

docker rmi $(docker images -q)

?6.运行tomcat

命令格式:

docker run -p 运行端口号:8080 tomcat:版本号

例:

[root@liuxin ~]# docker run -p 8085:8080:7.0.57

?7.删除所有未运行的容器

docker container prune

?8.以守护态运行容器

docker run -p 8085:8080 --name 容器名称(自定义) -d tomcat:7.0.57

?9.停止正在运行的容器

1)docker stop 容器ID
2)docker container stop 容器ID
3)docker container stop 容器的名字
4)停止所有正在运行的容器:docker stop $(docker ps -a -q)

?10.以数据卷的方式运行容器

docker run -p 8080:8080 --name tomcat12 -d -v /usr/local/docker/tomcat/ROOT:/usr/local/tomcat/webapps/ROOT tomcat:7.0.57

?11.以交互的方式进入容器

docker exec -it 容器的名字 bash

例:

docker exec -it tomcat12 bash
