基于alpine制作tomcat基础镜像

一 工作目录

root@k8s-harbor-01:/data/dockerfile/web/tomcat/tomcat-base# pwd
/data/dockerfile/web/tomcat/tomcat-base

二 下载tomcat

root@k8s-harbor-01:/data/dockerfile/web/tomcat/tomcat-base# wget https://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-8/v8.5.73/bin/apache-tomcat-8.5.73.tar.gz

三 编写Dockerfile

root@k8s-harbor-01:/data/dockerfile/web/tomcat/tomcat-base# cat Dockerfile 
FROM 192.168.174.120/baseimages/jdk-base:1.8.0_311


ENV TZ "Asia/Shanghai"
ENV TERM xterm
ENV TOMCAT_MAJOR_VERSION 8
ENV TOMCAT_MINOR_VERSION 8.5.73
ENV CATALINA_HOME /usr/local/tomcat
ENV APP_DIR /data/tomcat/webapps
ENV LANG en_US.UTF-8
ENV PATH $CATALINA_HOME/bin:$PATH


ADD apache-tomcat-8.5.73.tar.gz /usr/local/
RUN mkdir /data/tomcat/webapps /data/tomcat/logs -pv \
    && ln -sv /usr/local/apache-tomcat-8.5.73 /usr/local/tomcat

 
WORKDIR $CATALINA_HOME

四 编写构建镜像脚本

root@k8s-harbor-01:/data/dockerfile/web/tomcat/tomcat-base# cat build-command.sh 
#!/bin/bash

docker build -t 192.168.174.120/baseimages/tomcat-base:8.5.73 .
#docker push 192.168.174.120/baseimages/tomcat-base:8.5.73 .

五 构建镜像

root@k8s-harbor-01:/data/dockerfile/web/tomcat/tomcat-base# ./build-command.sh 
Sending build context to Docker daemon  10.59MB

六 验证镜像

6.1 启动服务

root@k8s-harbor-01:/data/dockerfile/web/tomcat/tomcat-base# docker run -it --rm -p 8080:8080  192.168.174.120/baseimages/tomcat-base:8.5.73 sh
/usr/local/apache-tomcat-8.5.73 # catalina.sh start
Using CATALINA_BASE:   /usr/local/tomcat
Using CATALINA_HOME:   /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME:        /usr/local/jdk/jre
Using CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
Using CATALINA_OPTS:   
Tomcat started.

6.2 访问web界面

七 上传镜像到harbor

root@k8s-harbor-01:/data/dockerfile/web/tomcat/tomcat-base# docker push 192.168.174.120/baseimages/tomcat-base:8.5.73
