构建tomcat镜像

[root@elk-node2 tomcat]# mkdir tomcat

[root@elk-node2 tomcat]# cd tomcat

[root@elk-node2 tomcat]# ls

apache-tomcat-8.5.16.tar.gz jdk1.8.0_191 jdk-8u191-linux-x64.tar.gz

FROM centos:latest

#维护该镜像的用户信息

MAINTAINER abc abc@163.com

#安装JDK环境，设置其环境变量

#RUN tar zxf jdk-8u191-linux-x86.tar.gz

ADD jdk1.8.0_191 /usr/local/jdk-8u191

ENV JAVA_HOME /usr/local/jdk-8u191

ENV JAVA_BIN /usr/local/jdk-8u191/bin

ENV JRE_HOME /usr/local/jdk-8u191/jre

ENV PATH $PATH:/usr/local/jdk-8u191/bin:/usr/local/jdk-8u191/jre/bin

ENV CLASSPATH /usr/local/jdk-8u191/jre/bin:/usr/local/jdk-8u191/lib:/usr/local/jdk-8u191/jre/lib/charsets.jar

#解压tomcat 并移动到响应位置

ADD apache-tomcat-8.5.16.tar.gz /usr/local/tomcat

#开启8080

[root@elk-node2 tomcat]# docker build -t tomcat:centos .

映射本地8080端口到容器的8080端口

[root@elk-node2 tomcat]# docker run -itd -p 8080:8080 tomcat:centos bash

812e52048354900515378927488e01206e39454ea2be732f39a428b10360fa6f

进入运行的容器，启动tomcat

[root@elk-node2 tomcat]# docker ps -a

CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

[root@elk-node2 tomcat]# docker exec -it 812 bash

[root@812e52048354 /]# /usr/local/tomcat/apache-tomcat-8.5.16/bin/startup.sh

Tomcat started.

[root@812e52048354 /]# exit
