DockerFile 自定义镜像Tomcat9
一、新建目录
二、 在上述目录下touch c.txt
三、将jdk和tomcat安装的压缩包拷贝进上一步目录
四、编写DockerFile
FROM centos MAINTAINER czy<> #把宿主机当前上下文的c.txt拷贝到容器/usr/local/路径下 COPY c.txt /usr/local/cincontainer.txt #把java与tomcat添加到容器中 ADD jdk-8u171-linux-x64.tar.gz /usr/local/ ADD apache-tomcat-9.0.30.tar.gz /usr/local/ #安装vim编辑器 RUN yum -y install vim #设置工作访问时候的WORKDIR路径，登录落脚点 ENV MYPATH /usr/local WORKDIR $MYPATH #配置java与tomcat环境变量 ENV JAVA_HOME /usr/local/jdk1.8.0_171 ENV CLASSPATH $JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar ENV CATALINA_HOME /usr/local/apache-tomcat-9.0.30 ENV CATALINA_BASE /usr/local/apache-tomcat-9.0.30 ENV PATH $PATH:$JAVA_HOME/bin:$CATALINA_HOME/lib:$CATALINA_HOME/bin #容器运行时监听的端口 EXPOSE 8080 #启动时运行tomcat # ENTRYPOINT ["/usr/local/apache-tomcat-9.0.30/bin/startup.sh" ] # CMD ["/usr/local/apache-tomcat-9.0.30/bin/catalina.sh","run"] CMD /usr/local/apache-tomcat-9.0.30/bin/startup.sh && tail -F /usr/local/apache-tomcat-9.0.30/bin/logs/catalina.out
五、构建
六、run
docker run -d -p 9080:8080 --name myt9 -v /czyuse/mydockerfile/tomcat9/test:/usr/local/apache-tomcat-9.0.30/webapps/test -v /czyuse/mydockerfile/tomcat9/tomcat9logs/:/usr/local/apache-tomcat-9.0.30/logs --privileged=true czytomcat9
七、验证
八、结合前述的容器卷将测试的web服务test发布
