标签: maven spring-boot docker dockerfile docker-build

我正在尝试为我的spring-boot应用程序构建一个docker映像。 这是我的Dockerfile:

FROM ubuntu
ENV JAVA_VERSION 8u31
ENV BUILD_VERSION b13
# Upgrading system
RUN apt-get -y upgrade
RUN apt-get -y install wget
# Downloading & Config Java 8
RUN wget --no-cookies --no-check-certificate --header "Cookie:

 pub/java/jdk/$JAVA_VERSION-$BUILD_VERSION/jdk-$JAVA_VERSION-linux- 
x64.rpm" -O /tmp/jdk-8-linux-x64.rpm
RUN apt-get -y install /tmp/jdk-8-linux-x64.rpm

RUN alternatives -- install  /usr/lib/jvm/java-8-oracle/jre/bin/java

RUN alternatives --install /usr/lib/jvm/java-8-openjdk- 
amd64/jre/bin/java   1081      
 RUN alternatives --install /usr/lib/jvm/java-8-oracle/jre/bin/java          
1081     


  EXPOSE 8089
  #install Spring Boot artifact
    VOLUME /tmp
    ADD /maven/sfg-thymeleaf-course-0.0.1-SNAPSHOT.jar sfg-thymeleaf- 
  course.jar
   RUN sh -c 'touch /sfg-thymeleaf-course.jar'
     ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","- 
   jar","/sfg-thymeleaf-course.jar"]

这是我的pom.xml文件,其中有io.fabric8插件:

当我尝试使用mvn package docker:build构建docker映像时 我遇到错误:

无法执行目标io.fabric8:docker-maven-plugin:0.15.3:build     (default-cli)在项目detailsapp上:执行目标的default-cli     io.fabric8:docker-maven-plugin:0.15.3:build失败。     NullPointerException-> [帮助1]

有人可以提供解决方案吗,将不胜感激。 谢谢!

答案 0 :(得分:0)

这对我有用,可以构建docker映像并将其推送到docker hub,我不使用docker文件,而是通过Fabric创建它:

mvn clean install fabric8:build fabric8:push

我的pom看起来像这样:
