前言

今天笔者在编写dockerfile的时候，报错了，咋一看编写的指令是没问题的，那是哪里出现了问题呢？下面跟着笔者来看看怎么解决这个问题吧！

报错如下：

ERROR [2/9] RUN yum install openssl                                                                                                                                                                                                       20.6s

解决方案

根据提供的错误信息，安装 OpenSSL 时出现了交互式提示，询问是否要继续安装。
Dockerfile 中的yum install openssl命令需要在非交互模式下运行，以避免等待用户输入。
通过在运行 yum install openssl 命令时添加 -y 标志来实现非交互式安装。

修改 Dockerfile 中的相应行如下：

RUN yum install -y openssl

这样，安装 OpenSSL 将自动确认，并且不会等待用户输入。
重新构建你的Docker镜像，应该就不会再出现这个错误了。

总结

一般，在dockerfile中用yum安装都会加上-y用于实现非交互式安装。这其实也是dockerfile和正常的交互式shell安装的不同之处。所以，大家在编写dockerfile使用yum安装时要注意加上-y来进行默认确定，确保安装正常。

看到这里的小伙伴，恭喜你又掌握了一个技能👊
希望大家能取得胜利，坚持就是胜利💪

1dafff06 When a requested parameter has a non-NULL result pointer, and the error isn't simply that the result buffer is too small, don't return a non-zero result size. Returning a non-zero result size that isn't larger than the user's provided space is an indication that a result of that size was actually written, inviting trouble if the error indication was inadvertenly lost. Also, in such cases (wrong type, data can't be converted to the requested type when otherwise supported, ...) there is nothing useful to be done with the return size value, it can't help to address the problem.
