docker实例-alpine-tomcat

docker实例-alpine-tomcat： 环境条件： 采取ADD方式来安装tomcat服务。 准备好：jdk/jre、 tomcat 解压后的文件。

实例一：

FROM frolvlad/alpine-glibc:latest
MAINTAINER lvv <123@qq.com>

#配置alpine软件更新/安装源
RUN echo "https://mirror.tuna.tsinghua.edu.cn/alpine/v3.8/main/" > /etc/apk/repositories

#更新alpine,并安装curl bash bash-doc bash-completion
RUN apk update \
        && apk upgrade \
        && apk add --no-cache unzip curl bash \
        bash-doc \
        bash-completion \
        && /bin/bash \
        && rm -rf /tmp/* /var/cache/apk/*;

ADD /jre-181 /usr/java/jre/
ADD /tomcat-8053 /usr/java/tomcat/
ADD run.sh /run.sh
RUN chmod 775 /run.sh


EXPOSE 8080
CMD ["/run.sh"]

run.sh代码：

#!/bin/bash
 

# set env
ENV JAVA_HOME /usr/java/jre
ENV PATH ${PATH}:${JAVA_HOME}/bin:$PATH

sh /usr/java/tomcat/bin/catalina.sh run

注：run.sh脚本是否可以直接放在tomcat或jdk之中，可以省略add的步骤。
