在linux上docker内网环境部署，怎样阻止docker去外网拉取java镜像，而采用本地的已有镜像

一、该问题的重现步骤是什么？

1. 我已经把bladex/alpine-java:openjdk8-openj9_cn_slim拉取到docker里了，我执行的命令是docker pull bladex/alpine-java:openjdk8-openj9_cn_slim

2. 内网环境下，centos7，docker部署，执行命令mvn dockerfile:build

3. 这是dockerfile文件，在执行第一条的时候报错

   
   FROM bladex/alpine-java:openjdk8-openj9_cn_slim MAINTAINER bladejava@qq.com RUN mkdir -p /blade/camera WORKDIR /blade/camera EXPOSE 9002 COPY ./solib /usr/local/lib/ ENV LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH ADD ./target/blade-camera.jar ./app.jar ENTRYPOINT ["java", "-Djava.security.egd=file:/dev/./urandom", "-jar", "app.jar"] CMD ["--spring.profiles.active=test"]

4. 这是执行命令后的报错信息

   org.apache.maven.plugin.MojoExecutionException: Could not build image

二、你期待的结果是什么？实际看到的又是什么？

我期待能够在内网环境下成功执行命令mvn dockerfile:build。

实际上我必须联网才能成功执行。

三、你正在使用的是什么产品，什么版本？在什么操作系统上？

bladex，在linux上

四、请提供详细的错误堆栈信息，这很重要。
