4、CentOS7 Docker 下 部署tomcat

1.搜索tomcat 镜像
docker search tomcat

[root@localhost ~]# docker search tomcat

2、拉取tomcat镜像
docker pull tomcat

[root@localhost ~]# docker pull tomcat
Using default tag: latest
latest: Pulling from library/tomcat
e79bb959ec00: Pull complete 
d4b7902036fe: Pull complete 
1b2a72d4e030: Pull complete 
de423484a946: Pull complete 
ceaac3b844f7: Pull complete 
88f01b722a52: Pull complete 
c23be56a9ac1: Pull complete 
d852ffd6d31f: Pull complete 
11775a3d792d: Pull complete 
13fdd17462ac: Pull complete 
2092995a1e54: Pull complete 
Digest: sha256:6cb1b64fa315eab22803c7cde8408b91dedba8fbf5f01d4def96d95f79344a17
Status: Downloaded newer image for tomcat:latest

3、查看镜像是否拉取成功
docker images

[root@localhost ~]# docker images
REPOSITORY                TAG                 IMAGE ID            CREATED             SIZE
tomcat                    latest              5a069ba3df4d        3 weeks ago         465MB
centos/mysql-57-centos7   latest              e35b3f7a4ea0        4 weeks ago         452MB
centos                    latest              9f38484d220f        7 weeks ago         202MB

4、启动容器
需要在宿主机 上提前创建路径
-v 是做目录映射
-p 是做端口映射

 docker run -di --name=tomcat -p 8080:8080 -v /usr/local/webapps:/usr/local/tomcat/webapps tomcat

5、测试
写一个index.html
放到宿主机的/usr/local/webapps/ROOT目录下。
因为已经挂在了容器的tomcat路径所以 直接访问宿主机的8080端口 就可以访问到了index.html
