使用maven插件自动部署web应用至Docker容器的tomcat

在pom.xml加入

<plugins>

    <plugin>

        <groupId>org.apache.tomcat.maven</groupId>

        <artifactId>tomcat7-maven-plugin</artifactId>

        <version>2.2</version>

        <configuration>

            <url>https://192.168.1.106:8081/manager/text</url>

            <server>tomcat</server>

            <username>deploy</username>

            <password>deploy</password>

        </configuration>

    </plugin>

</plugins>

在maven的settings.xml加入

创建个人的Docker镜像

创建Dockerfile文件

mkdir -p /usr/local/dockerfile/massive
cd /usr/local/dockerfile/massive
touch Dockerfile

编辑Dockerfile

from tomcat:7
MAINTAINER massive
ADD tomcat-users.xml /usr/local/tomcat/conf/

注：tomcat-users.xml可以在tomcat/conf目录找到，拷贝一个到此目录

在tomcat-users.xml加入以下内容

3

<role rolename="manager-gui"/>

<role rolename="manager-script"/>

<user username="deploy" password="deploy" roles="manager-gui, manager-script"/>

build这个镜像

1	`docker build -t massive:tomcat .`

运行个人定制的Docker镜像

1	`docker run -p` `8081:8080` `massive:tomcat`

将web应用部署至容器里运行的tomcat

1	`mvn tomcat7:deploy`

web应用会通过tomcat的部署机制拷贝至容器的 /usr/local/tomcat/webapps/${project} 下，当Docker容器关闭后，容器内的改动不会保存至镜像，也就是说拷贝至容器的web应用会在容器关闭后被删除。

配置maven

在pom.xml加入
