1、先要选取一个基板docker镜像,此处选用tomcat:8-jre8

2、通过基板镜像,build一个自有镜像:


Dockerfile:

FROM tomcat:8-jre8

MAINTAINER "Liu Li " 

ADD settings.xml /usr/local/tomcat/conf/
ADD tomcat-users.xml /usr/local/tomcat/conf/

settings.xml:


 

TomcatServer
admin
adm123
 

tomcat-users.xml:






这三个文件放在同一个文件夹里,然后在那个文件夹里执行:


 docker build -t my_tomcat:8-jre8 .

3、通过设定的自有镜像启动一个容器:


 docker run -d -p 8080:8080  my_tomcat:8-jre8

访问ip:8080可以获得tomcat的欢迎页

ip/manager可以获得tomcat的管理页面:登录用户名密码在上面文件中配置


4、maven管理的工程中的pom文件中:


注:如果pom中带s的复数标签已有,只需要将内容添加到标签下即可:

比如:

文件中已经存在plugins标签,往其中添加:


   
            
                xxxxxxxxxxxxxxxxxx  
                xxxxxxxxxxxxxxxxxx  
                xxxxxxxxxxx  
              
         .
         .
         .
              
                org.apache.maven.plugins  
                maven-compiler-plugin  
                3.1  
              
              
                org.apache.tomcat.maven  
                tomcat7-maven-plugin  
                2.2  
                
                    8080   
                    UTF-8
                    http://localhost:8080/manager/text  
                    admin  
                    adm123  
                    /${project.artifactId}  
                  
              


文件中存在properties标签时:


  
        .
        .
        .
        UTF-8  
        deploy  
        8.0.0-RC5  



文件中存在dependencies标签:


 
           
            xxxxxxxxxx  
            xxxxxxxxxxxx  
            xxxxxxxxxxxxx  
            xxxxxxxxxxxx  
         
        .
        .
        .
          
            org.apache.tomcat  
            tomcat-servlet-api  
            ${project.tomcat.version}  
            provided  
         
  



pom.xml:

localhost改成你部署的主机的ip

  
        UTF-8  
        deploy  
        8.0.0-RC5  
  
 
          
            org.apache.tomcat  
            tomcat-servlet-api  
            ${project.tomcat.version}  
            provided  
         
    
    
          
              
                org.apache.maven.plugins  
                maven-compiler-plugin  
                3.1  
              
              
                org.apache.tomcat.maven  
                tomcat7-maven-plugin  
                2.2  
                
                    8080   
                    UTF-8
                    http://localhost:8080/manager/text  
                    admin  
                    adm123  
                    /${project.artifactId}  
                  
              
          
    



5、完成之后,在项目工程文件夹中执行:


含义:构建并将工程部署到tomcat中,跳过单元测试。


mvn -Dmaven.test.skip=true tomcat7:deploy -e

结果如:

我的工程名字叫busimgnt,此时访问:

我的ip:8080/busimgnt,我的index中只写了hello world,因此访问后得到了该字符串,这时候,热部署就完成了,下次打包之后,执行本命令,就可以将新包热部署。
