在构建我的 docker 文件时，我得到一个返回的非零代码：8

Question

我正在通过docker设置Kafka和zookeeper；然而，每当我构建我的图像时，我总是收到代码 8 错误：

wget -q  https://www.apache.org/dist/zookeeper/zookeeper-${ZOOKEEPER_VERSION}/zookeeper-${ZOOKEEPER_VERSION}.tar.gz.asc .

我已经尝试将下载中的文件格式更改为 unixkafka.sh。

下面是我的docker文件：

FROM Wurstmeister/base

ENV ZOOKEEPER_VERSION 3.4.13

#Download Zookeeper

如果你去这个link，那么3.4.13就不存在了

https://www.apache.org/dist/zookeeper/

您可以更改为 ENV ZOOKEEPER_VERSION 3.4.14，或者只使用现有的 Zookeeper Docker 图像
