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)
7.0.82-jre7-alpine, 7.0-jre7-alpine, 7-jre7-alpine, 7.0.82-alpine, 7.0-alpine, 7-alpine (7/jre7-alpine/Dockerfile)
7.0.82-jre8, 7.0-jre8, 7-jre8 (7/jre8/Dockerfile)
7.0.82-jre8-alpine, 7.0-jre8-alpine, 7-jre8-alpine (7/jre8-alpine/Dockerfile)
8.0.47-jre7, 8.0-jre7, 8.0.47, 8.0 (8.0/jre7/Dockerfile)
8.0.47-jre7-alpine, 8.0-jre7-alpine, 8.0.47-alpine, 8.0-alpine (8.0/jre7-alpine/Dockerfile)
8.0.47-jre8, 8.0-jre8 (8.0/jre8/Dockerfile)
8.0.47-jre8-alpine, 8.0-jre8-alpine (8.0/jre8-alpine/Dockerfile)
8.5.24-jre8, 8.5-jre8, 8-jre8, jre8, 8.5.24, 8.5, 8, latest (8.5/jre8/Dockerfile)
8.5.24-jre8-alpine, 8.5-jre8-alpine, 8-jre8-alpine, jre8-alpine, 8.5.24-alpine, 8.5-alpine, 8-alpine, alpine (8.5/jre8-alpine/Dockerfile)
9.0.2-jre8, 9.0-jre8, 9-jre8, 9.0.2, 9.0, 9 (9.0/jre8/Dockerfile)
9.0.2-jre8-alpine, 9.0-jre8-alpine, 9-jre8-alpine, 9.0.2-alpine, 9.0-alpine, 9-alpine (9.0/jre8-alpine/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
