[[toc]]

[toc]

查找tomcat并且下载

root@ubuntu:/tmp/host_data# docker search --help 

Usage:  docker search [OPTIONS] TERM

Search the Docker Hub for images

Options:
  -f, --filter filter   Filter output based on conditions provided
      --format string   Pretty-print search using a Go template
      --limit int       Max number of search results (default 25)
      --no-trunc        Don't truncate output
root@ubuntu:/tmp/host_data# docker search --limit 3  tomcat

root@ubuntu:/tmp/host_data# docker run -it tomcat /bin/bash

运行

docker run -d -p 8080:8080 --name tomcat01 tomcat

可以使用-P随机分配端口，此时内部和外部端口会不一样

root@ubuntu:/tmp/host_data# docker run -d -P --name tomcat02 tomcat

我们使用docker ps查看端口号

访问猫首页

为什么上面的tomcat上面啥没有猫猫？

因为这是新版，我们进入tomcat看一下

root@ubuntu:/tmp/host_data# docker ps

这是因为真正有货的是webapps.dist，而web apps里面是空的，此时我们删除并且改名

root@9e194dbf7eca:/usr/local/tomcat/webapps# cd .. &&rm -r webapps
root@9e194dbf7eca:/usr/local/tomcat# mv webapps.dist/ webapps &&cd webapps &&ls -al

如上图，成功了（我设置了映射）

推荐使用的版本

我们的版本是最新的tomcat，其实用不到这么新的，可以删除后重新安装一个旧的

docker run -d -p 8080:8080 --name tomcat03 billygoo/tomcat8-jdk8

查看端口

建议初学者使用后面的方法就行
