叁歲伎倆 2022-10-22 02:55 444阅读 0赞

### 基于Dockerfile构建tomcat容器 ###

*  下载tomcat.tar.gz包
 *  配置tomcat管理界面以及用户
 *  编写Dockerfile文件
 *  构建tomcat镜像
 *  启动容器
 *  访问页面
 *  Manager App页面
 *  HostManager
 *  Server Status
 *  附加docker-compose配置一份

`以下所有内容打包资源`  
`附加此次部署的tomcat，ssl，docker-compose所有内容`  
[tomcat-deploy-docker][]

# 下载tomcat.tar.gz包 #

wget https://mirrors.bfsu.edu.cn/apache/tomcat/tomcat-9/v9.0.44/bin/apache-tomcat-9.0.44.tar.gz
    # 解压
    tar zxvf apache-tomcat-9.0.44.tar.gz

# 配置tomcat管理界面以及用户 #

修改manager host-manage目录的下级目录META-INFO下面的context.xml文件，开启管理页面  
替换以下内容到context.xml

<?xml version="1.0" encoding="UTF-8"?>
    <Context antiResourceLocking="false" privileged="true" >
      <CookieProcessor className="org.apache.tomcat.util.http.Rfc6265CookieProcessor" sameSiteCookies="strict" />
      <Valve className="org.apache.catalina.valves.RemoteAddrValve" allow="\d+\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />
      <Manager sessionAttributeValueClassNameFilter="java\.lang\.(?:Boolean|Integer|Long|Number|String)|org\.apache\.catalina\.filters\.CsrfPreventionFilter\$LruCache(?:\$1)?|java\.util\.(?:Linked)?HashMap"/>
    </Context>

进入tomcat下的conf目录，替换以下内容到tomcat-users.xml

<?xml version="1.0" encoding="UTF-8"?>
    <tomcat-users xmlns="http://tomcat.apache.org/xml" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://tomcat.apache.org/xml tomcat-users.xsd" version="1.0">
        <role rolename="admin-gui"/>
        <role rolename="admin-script"/>
        <role rolename="manager-gui"/>
        <role rolename="manager-script"/>
        <role rolename="manager-jmx"/>
        <role rolename="manager-status"/>
        
        <user username="tomcat" password="123456" roles="manager-gui,manager-script,manager-jmx,manager-status,admin-script,admin-gui"/>
    </tomcat-users>

# 编写Dockerfile文件 #

dockerfile和tomcat必须处于同级目录

FROM adoptopenjdk/openjdk11:x86_64-alpine-jre-11.0.9_11

     #定义tomcat
    ENV TOMCAT_APP apache-tomcat-9.0.44
     #定义tomcat工作目录
    ENV WORKDIR /opt/tomcat
    # tomcat启动会加载这个环境变量
    ENV JAVA_OPTS "-Xmx128m -Xms128m -Xmn32m -Xss512k  -XX:+HeapDumpOnOutOfMemoryError  -XX:HeapDumpPath=$WORKDIR/error -Duser.timezone=Asia/Shanghai" 
    #挂载error目录
    VOLUME /opt/tomcat/error
    # 配置时区
    RUN sed -i 's/dl-cdn.alpinelinux.org/mirrors.aliyun.com/g' /etc/apk/repositories \
            && apk update \
            && apk add --no-cache tzdata \
            && cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
     # 设置时区
    ENV TZ Asia/Shanghai
    # 设置工作目录
    WORKDIR $WORKDIR
    # 将tomcat拷贝到工作目录
    COPY $TOMCAT_APP .
    # 暴露端口
    EXPOSE 8080
    # 启动tomcat
    CMD $WORKDIR/bin/catalina.sh run

# 构建tomcat镜像 #

当前目录如下图，tomcat和Docker必须处于同级目录  
![在这里插入图片描述][20210403120910418.png]  
执行构建命令，构建tomcat

# -t 设置镜像的tag标签
    docker build -t tomcat:9.0.44-alpine .

构建完成效果如下

# 启动容器 #

docker run --name tomcat -p 8080:8080 -d tomcat:9.0.44-alpine

# Manager App页面 #

需要输入用户名和密码，刚刚自定义的是tomcat 123456
