Docker 构建Tomcat镜像

1、首先下载好jre、tomcat

• server-jre-8u51-linux-x64.gz
• apache-tomcat-8.0.24.tar.gz

2、新建Dockerfile文件，内容如下:

FROM ubuntu
ADD server-jre-8u51-linux-x64.gz /usr/local
ADD apache-tomcat-8.0.24.tar.gz /usr/local
RUN mv /usr/local/apache-tomcat-8.0.24 /usr/local/tomcat
ENV CATALINA_HOME /usr/local/tomcat
ENV JAVA_HOME /usr/local/jdk1.8.0_51
EXPOSE 8080
ENV PATH $PATH:$JAVA_HOME/bin

3、构建镜像

$ docker build -t tomcat .

4、运行

$ docker run --name tomcat -d -v /home/webapps:/usr/local/tomcat/webapps -p 8080:8080 tomcat /usr/local/tomcat/bin/catalina.sh

<script type="text/javascript"> $(function () { $('pre.prettyprint code').each(function () { var lines = $(this).text().split('\n').length; var $numbering = $('<ul/>').addClass('pre-numbering').hide(); $(this).addClass('has-numbering').parent().append($numbering); for (i = 1; i <= lines; i++) { $numbering.append($('<li/>').text(i)); }; $numbering.fadeIn(1700); }); }); </script>
