Spring Web集成Docker

• 根目录创建docker 文件夹

  docker

  |– webapps（web目录）

  |– Dockerfile

• dockerfile

  FROM tomcat:8.0

  ENV CATALINA_HOME /usr/local/tomcat

  WORKDIR $CATALINA_HOME

  # start modify
  RUN cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
  RUN echo “Asia/Shanghai” > /etc/timezone

  # copy war
  COPY webapps/*.war /usr/local/tomcat/webapps/

  EXPOSE 8080
  CMD [“catalina.sh”, “run”]

• pom.xml 增加插件

  \<plugins\>

  <plugin>
  <artifactId>maven-war-plugin</artifactId>
  <configuration>
  <!–设置将war包打包至webapps下–>
  <outputDirectory>${basedir}/docker/webapps</outputDirectory>
  </configuration>
  </plugin>
  <plugin>
  <groupId>com.spotify</groupId>
  <artifactId>docker-maven-plugin</artifactId>
  <version>0.4.13</version>
  <configuration>
  <imageName>${project.name}:${project.version}</imageName>
  <!–Dockerfile文件位置–>
  <dockerDirectory>${basedir}/docker</dockerDirectory>
  </configuration>
  </plugin>
  </plugins>

• 执行 mvn clean package docker:build

  若镜像需要发布则执行 mvn clean package docker:build -DpushImage

• 执行 docker run -p 8080:8080 -it ${project.name}:${project.version}

附无需maven打包docker方法

• 启动docker 并将webapps挂载出来
  docker run -p 8080:8080 -v /usr/local/tomcat/webapps/:/usr/local/tomcat/webapps/ -it tomcat:8.0

• 将war包复制到挂载目录
  cp webapps/*.war /usr/local/tomcat/webapps/

• 重启docker
  docker restart ${container}
