拉取镜像

这里我们拉取官方的镜像

[root@controller ~]# docker pull tomcat

Using default tag: latest
latest: Pulling from library/tomcat
e79bb959ec00: Downloading [===================================>               ]   31.9MB/45.34MB

ceaac3b844f7: Downloading

等待下载完成后，我们就可以在本地镜像列表里查到REPOSITORY为tomcat的镜像。

[root@controller ~]# docker images|grep tomcat

tomcat              latest              5a069ba3df4d        Less than a second ago   465MB

使用用tomcat镜像

运行容器

runoob@runoob:~/tomcat$ docker run --name tomcat -p 8080:8080 -v $PWD/test:/usr/tomcat/webapps/test -d tomcat

acb33fcb4beb8d7f1ebace6f50f5fc204b1dbe9d524881267aa715c61cf75320

命令说明：

-p 8080:8080：将容器的8080端口映射到主机的8080端口

-v $PWD/test:/usr/local/tomcat/webapps/test：将主机中当前目录下的test挂载到容器的/test

查看容器启动情况

runoob@runoob:~/tomcat$ docker ps

CONTAINER ID    IMAGE     COMMAND               ... PORTS                    NAMES
acb33fcb4beb    tomcat    "catalina.sh run"     ... 0.0.0.0:8080->8080/tcp   tomcat

通过浏览器访问: http://10.0.0.20:8080/

(10.0.0.20为宿主机IP)
