我试图将java 8和elasticsearch安装到我的ruby图像中。
添加我手动配置时经常使用的配置会导致错误并始终失败。
然后我尝试添加java和elasticsearch最新官方docker镜像中使用的配置。
我的Dockerfile现在如下：

然而，现在我被弹力研究所困住了。当我到达RUN gpg --keyserver ha.pool.sks-keyservers.net --recv-keys B42F6819007F00F88E364FD4036A9C25BF357DD4时，我得到以下内容：
gpg: directory '/root/.gnupg' created
gpg: keybox '/root/.gnupg/pubring.kbx' created
gpg: keyserver receive failed: Cannot assign requested address
The command '/bin/sh -c gpg --keyserver ha.pool.sks-keyservers.net --recv-keys B42F6819007F00F88E364FD4036A9C25BF357DD4' returned a non-zero code: 2
请帮忙吗？
