docker、maven、tomcat8自动部署配置方法

321231255

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 <lich@lichdiamond.win>"

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

settings.xml:

<?xml version="1.0" encoding="UTF-8"?>
<settings>
<servers>
<server>
<id>TomcatServer</id>
<username>admin</username>
<password>adm123</password>
</server>
</servers>

tomcat-users.xml:

<?xml version='1.0' encoding='utf-8'?>
<tomcat-users>
<role rolename="manager-gui"/>
<role rolename="manager-gui"/>
<role rolename="manager-script"/>
<user username="admin" password="adm123" roles="manager,manager-gui,manager-script" />
</tomcat-users>

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：


<plugins>  
            <plugin>
                <groupId>xxxxxxxxxxxxxxxxxx</groupId>  
                <artifactId>xxxxxxxxxxxxxxxxxx</artifactId>  
                <version>xxxxxxxxxxx</version>  
            </plugin>  
         .
         .
         .
            <plugin>  
                <groupId>org.apache.maven.plugins</groupId>  
                <artifactId>maven-compiler-plugin</artifactId>  
                <version>3.1</version>  
            </plugin>  
            <plugin>  
                <groupId>org.apache.tomcat.maven</groupId>  
                <artifactId>tomcat7-maven-plugin</artifactId>  
                <version>2.2</version>  
                <configuration>
                    <port>8080</port>   
                    <uriEncoding>UTF-8</uriEncoding>
                    <url>http://localhost:8080/manager/text</url>  
                    <username>admin</username>  
                    <password>adm123</password>  
                    <path>/${project.artifactId}</path>  
                </configuration>  
            </plugin>  
</plugins>


文件中存在properties标签时：


<properties>  
        .
        .
        .
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>  
        <project.deploy>deploy</project.deploy>  
        <project.tomcat.version>8.0.0-RC5</project.tomcat.version>  
</properties>



文件中存在dependencies标签：


<dependencies>
         <dependency>  
            <groupId>xxxxxxxxxx</groupId>  
            <artifactId>xxxxxxxxxxxx</artifactId>  
            <version>xxxxxxxxxxxxx</version>  
            <scope>xxxxxxxxxxxx</scope>  
        </dependency>
        .
        .
        .
        <dependency>  
            <groupId>org.apache.tomcat</groupId>  
            <artifactId>tomcat-servlet-api</artifactId>  
            <version>${project.tomcat.version}</version>  
            <scope>provided</scope>  
        </dependency>
  </dependencies>



pom.xml:

localhost改成你部署的主机的ip

<properties>  
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>  
        <project.deploy>deploy</project.deploy>  
        <project.tomcat.version>8.0.0-RC5</project.tomcat.version>  
</properties>  
<dependencies>
        <dependency>  
            <groupId>org.apache.tomcat</groupId>  
            <artifactId>tomcat-servlet-api</artifactId>  
            <version>${project.tomcat.version}</version>  
            <scope>provided</scope>  
        </dependency>
  </dependencies>  
  <build>  
        <plugins>  
            <plugin>  
                <groupId>org.apache.maven.plugins</groupId>  
                <artifactId>maven-compiler-plugin</artifactId>  
                <version>3.1</version>  
            </plugin>  
            <plugin>  
                <groupId>org.apache.tomcat.maven</groupId>  
                <artifactId>tomcat7-maven-plugin</artifactId>  
                <version>2.2</version>  
                <configuration>
                    <port>8080</port>   
                    <uriEncoding>UTF-8</uriEncoding>
                    <url>http://localhost:8080/manager/text</url>  
                    <username>admin</username>  
                    <password>adm123</password>  
                    <path>/${project.artifactId}</path>  
                </configuration>  
            </plugin>  
        </plugins>  
    </build>



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。
