Docker之tomcat操作

Love The Way You Lie 2023-05-29 13:21 0阅读 0赞

1.创建tomcat7.0\_jdk1.6文件夹，从www.oracle.com网站上下载sun\_jdk.1.6压缩包加压为jdk目录

2.创建Dockerfile和run.sh文件

$mkdir tomcat7.0_jdk1.6
    cd tomcat7.0_jdk1.6/
    touch Dockerfile run.sh

3.下载tomcat：wget http://mirror.bit.edu.cn/apache/tomcat/tomcat-7/v7.0.56/bin/apache-tomcat-  
7.0.56.zip

4.编辑Dockerfile文件：

FROM sshd:Dockerfile
    #设置继承自用户创建的sshd镜像
    MAINTAINER docker_user (user@docker.com)
    #下面是一些创建者的基本信息
    #设置环境变量，所有操作都是非交互式的
    ENV DEBIAN_FRONTEND noninteractive
    #注意这里要更改系统的时区设置
    RUN echo "Asia/Shanghai" > /etc/timezone && \
    dpkg-reconfigure -f noninteractive tzdata
    #安装跟tomcat用户认证相关的软件
    RUN apt-get install -yq --no-install-recommends wget pwgen ca-certificates && \
    apt-get clean && \
    rm -rf /var/lib/apt/lists/*
    #设置tomcat的环境变量，若读者有其他的环境变量需要设置，也可以在这里添加。
    ENV CATALINA_HOME /tomcat
    ENV JAVA_HOME /jdk
    #复制tomcat和jdk文件到镜像中
    ADD apache-tomcat-7.0.56 /tomcat
    ADD jdk /jdk
    ADD create_tomcat_admin_user.sh /create_tomcat_admin_user.sh
    ADD run.sh /run.sh
    RUN chmod +x /*.sh
    RUN chmod +x /tomcat/bin/*.sh
    EXPOSE 8080
    CMD ["/run.sh"]

创建tomcat用户和密码脚本文件create\_tomcat\_admin\_user.sh文件，内容  
为：

#!/bin/bash
    if [ -f /.tomcat_admin_created ]; then
    echo "Tomcat 'admin' user already created"
    exit 0
    fi
    #generate password
    PASS=${TOMCAT_PASS:-$(pwgen -s 12 1)}
    _word=$( [ ${TOMCAT_PASS} ] && echo "preset" || echo "random" )
    echo "=> Creating and admin user with a ${_word} password in Tomcat"
    sed -i -r 's/<\/tomcat-users>//' ${CATALINA_HOME}/conf/tomcat-users.xml
    echo '<role rolename="manager-gui"/>' >> ${CATALINA_HOME}/conf/tomcat-users.xml
    echo '<role rolename="manager-script"/>' >> ${CATALINA_HOME}/conf/tomcat-users.xml
    echo '<role rolename="manager-jmx"/>' >> ${CATALINA_HOME}/conf/tomcat-users.xml
    echo '<role rolename="admin-gui"/>' >> ${CATALINA_HOME}/conf/tomcat-users.xml
    echo '<role rolename="admin-script"/>' >> ${CATALINA_HOME}/conf/tomcat-users.xml
    echo "<user username=\"admin\" password=\"${PASS}\" roles=\"manager-gui,managerscript,manager-jmx,admin-gui, admin-script\"/>" >> ${CATALINA_HOME}/conf/
    tomcat-users.xml
    echo '</tomcat-users>' >> ${CATALINA_HOME}/conf/tomcat-users.xml
    echo "=> Done!"
    touch /.tomcat_admin_created
    echo "========================================================================"
    echo "You can now configure to this Tomcat server using:"
    echo ""
    echo " admin:${PASS}"
    echo ""
    echo "========================================================================"

创建run.sh脚本

#!/bin/bash
    if [ ! -f /.tomcat_admin_created ]; then
    /create_tomcat_admin_user.sh
    fi
    /usr/sbin/sshd -D &
    exec ${CATALINA_HOME}/bin/catalina.sh run

开始创建镜像：docker build -t tomcat7.0:jdk1.6

启动镜像：docker run -d -P tomcat7.0:jdk1.6

通过docker logs 3cd ch得到tomcat的密码 aBwN0CNCPckw

$ docker logs 3cd  
=> Creating and admin user with a random password in Tomcat  
=> Done!  
========================================================================  
You can now configure to this Tomcat server using:  
admin:aBwN0CNCPckw

在实际环境中，可以通过使用-v 参数来挂在Tomcat的日志文件，程序所在目录、以及与tomcat相关的配置
