运行docker build时不反映对我的dockerfile的更改 [英] Changes to my dockerfile are not reflected when running `docker build`

问题描述

Docker初学者在这里.我正在尝试通过调用 docker build -t my_image.并在失败的行上对dockerfile进行更改来构建docker镜像.我目前在此行遇到问题:

Docker beginner here. I'm trying to build a docker image by invoking docker build -t my_image . and making changes to the dockerfile on lines that fail. I'm currently running into a problem on this line:

运行apt-get install -qy语言环境

之前曾被纠正过的人:

运行apt-get install -q语言环境(我忘了 -y 假定为"yes"输入.)

RUN apt-get install -q locales (I forgot the -y which assumes 'yes' inputs.)

但是，当我再次运行build命令时，似乎未反映出对 -qy 的更改:

But, when I run the build command again, the change to -qy is seemingly not reflected:

 ---> Running in bc68a3eec929

The command '/bin/sh -c apt-get install -q locales' returned a non-zero code: 1

我尝试过的事情:

• 删除所有最近停止的容器

• Removing any recently stopped containers

删除所有最近生成的图像(全部失败)

Removing any recently built images (which were all failed)

使用 docker build --no-cache -t my_image.

请注意，我没有在dockerfile中使用VOLUME.我看到一些用户对此有疑问，但这不是我的问题.

Note that I do not use VOLUME in the dockerfile. I saw some users had problems with this, but it's not my issue.

简而言之，为什么在构建命令期间无法识别对我的dockerfile的更改?

In short, why are changes to my dockerfile not recognized during the build command?

推荐答案

基于您提到的内容，我认为第一个失败不是由于 -qy 引起的，它一定是由于未更新引起的在运行 apt-get 命令之前，请使用存储库.

Based on what you have mentioned, I think the first failure is not due to -qy, it must be due to not updating the repos before running the apt-get commands.

您可以试试看吗?

RUN apt-get update && apt-get install -qy locales
