1.首先查看下仓库镜像
docker search tomcat
[root@k8s~]# docker search tomcat

2.然后从hub.docker.com或者第三方有加速的docker网站查看tomcat镜像版本
阿里云tomcat docker镜像连接
7.0.82-jre7, 7.0-jre7, 7-jre7, 7.0.82, 7.0, 7 (7/jre7/Dockerfile)

3.我选择8.5.24版本下载
docker pull tomcat:8.5.24
[root@k8s~]# docker pull tomcat:8.5.24
8.5.24: Pulling from library/tomcat

Status: Downloaded newer image for tomcat:8.5.24
4.查看本地镜像 可以看到已经在本地仓库
docker images
[root@k8s~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
tomcat 8.5.24 66bbed06c8cd 2 weeks ago 557MB
5.开启tomcat一个容器(就是我们平常所说的实例)
docker run --name tomcat8.5.24 -d -v /etc/localtime:/etc/localtime:ro -p 8080:8080 tomcat:8.5.24
[root@k8s~]# docker run --name tomcat8.5.24 -d -v /etc/localtime:/etc/localtime:ro -p 8080:8080 tomcat:8.5.24
432bd371973ffb651083142f79913b675a8c400a7d011e7a5d3b4f70817f25b2
[root@k8s~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
432bd371973f tomcat:8.5.24 "catalina.sh run" 56 seconds ago Up 54 seconds 0.0.0.0:8080->8080/tcp tomcat8.5.24
-v /etc/localtime:/etc/localtime:ro 设置容器的时间与宿主机同步
–name tomcat8.5.24 :添加备注名
-p 8080:8080 :实体机的8080端口映射容器的8080
docker ps :查看正在运行的容器
6.tomcat远程访问
外网地址:8080
如果是阿里云esc服务器,安全组8080端口要开放
7.如果是在同一个docker下的容器要连接tomcat
7.1别名访问
比如tomcat2连接tomcat1,那tomcat2的启动参数里要加–link连接
docker run -d -v /etc/localtime:/etc/localtime:ro --name tomcat1 tomcat:8.5.24
docker run -d -v /etc/localtime:/etc/localtime:ro --name tomcat2 --link tomcat1:tomcat1_随意别名 tomcat:8.5.24
在tomcat2容器里的tomcat连接地址就写为-->别名:8080
比如：http://192.168.123.123:8080
就写为:http://tomcat1_随意别名:8080
7.2内网ip访问(相当于局域网访问)
获取tomcat容器内网ip地址
docker inspect --format='{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' tomcat8.5.24
[root@k8s~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
432bd371973f tomcat:8.5.24 "catalina.sh run" 12 minutes ago Up 12 minutes 0.0.0.0:8080->8080/tcp tomcat8.5.24
1794aed7cfe1 mysql:5.6.38 "docker-entrypoint.s…" 3 hours ago Up About an hour 0.0.0.0:3306->3306/tcp mysql5.6.38
[root@k8s~]# docker inspect --format='{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' 1794aed7cfe1
172.17.0.3
获取tomcat容器内网ip地址也可以使用管道过滤
docker inspect 1794aed7cfe1 | grep IPAddress
[docker@k8s~]# docker inspect 1794aed7cfe1|grep IPAddress
"SecondaryIPAddresses": null,
"IPAddress": "172.17.0.3",
"IPAddress": "172.17.0.3"
在tomcat容器里的mysql连接地址就写为:内网ip
比如：jdbc:mysql://192.168.123.123:3306
jdbc:mysql://172.17.0.3:3306
8.进入tomcat容器
docker exec -it 容器名字或者id /bin/bash
[root@k8s~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
432bd371973f tomcat:8.5.24 "catalina.sh run" 38 minutes ago Up 38 minutes 0.0.0.0:8080->8080/tcp tomcat8.5.24
[root@k8s~]# docker exec -it 432bd371973f /bin/bash
root@432bd371973f:/usr/local/tomcat#
拿到shell,收工
