自制tomcat镜像

1.编写dockerfile

FROM centos
MAINTAINER raygift@qq.com

# 安装vim
RUN yum -y install vim net-tools

ENV BASEPATH /usr/local
WORKDIR $BASEPATH

ADD jdk-8u201-linux-x64.tar.gz /usr/local/
ADD apache-tomcat-9.0.6.tar.gz /usr/local/

# 配置java与tomcat环境变量
ENV JAVA_HOME /usr/local/jdk1.8.0_201
ENV CLASSPATH $JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
ENV CATALINA_HOME /usr/local/apache-tomcat-9.0.6
ENV CATALINA_BASE /usr/local/apache-tomcat-9.0.6
ENV PATH $PATH:$JAVA_HOME/bin;$CATALINA_HOME/lib:$CATALINA_HOME/bin

EXPOSE 8080

# 启动时运行tomcat
#ENTRYPOINT ["$TOMCAT_PATH/bin/startup.sh" ]
#CMD ["$TOMCAT_PATH/bin/catalina.sh","run"]
CMD /usr/local/apache-tomcat-9.0.6/bin/startup.sh && tail -F /usr/local/apache-tomcat-9.0.6/bin/logs/catalina.out
    

2.生成镜像

[root@docker dockerfile]# docker build -t tomcat .

3.生成容器

[root@docker ~]# docker run -d -p 9080:8080 --name tomcat -v /tomcat/data:/usr/local/apache-tomcat-9.0.6/webapps/data -v /tomcat/logs:/usr/local/apache-tomcat-9.0.6/logs --privileged=true tomcat9
