Dockerfile"RUN chmod"没有生效 [英] Dockerfile "RUN chmod" not taking effect
问题描述
其他所有内容均生效，但权限没有更改，我是否缺少某些内容?
Everything else takes effect but permissions are not changing, am I missing something?
FROM joomla:3.9-php7.2-apache
RUN apt-get update \
&& apt-get install -y apt-utils vim curl
COPY ./joomla_html /var/www/html
RUN chmod -R 765 /var/www/html/
RUN chown -R www-data. /var/www/html/
RUN chmod -R 777 /var/www/html/tmp
RUN chmod -R 777 /tmp
RUN chmod -R 777 /var/www/html/modules
RUN chmod -R 777 /var/www/html/components
RUN chmod -R 777 /var/www/html/administrator/logs
RUN chmod -R 777 /var/www/html/images
RUN chmod -R 777 /var/www/html/uploads
COPY ./docker/php.ini /usr/local/etc/php/conf.d/php-extras.ini
EXPOSE 80
这就是我得到的，每个文件都具有1000:1000的权限，我需要它是www-data
This is what I get, every file has permissions to 1000:1000, I need it to be to www-data
ls -la/var/www/html的输出为
Output of ls -la /var/www/html is
total 144

drwxr-xr-x 1 root root 4096 May 8 02:30 ..

推荐答案
The directory is defined as a volume upstream: https://github.com/joomla/docker-joomla/blob/d34ff24288dfb5b27a167f870f1fcca56077be78/php7.2/apache/Dockerfile#L64
VOLUME /var/www/html
无法使用RUN命令修改卷.它们从具有该卷的临时容器开始，并且仅保存对该容器的更改，而不保存该卷.
Volumes cannot be modified with a RUN command. They start in a temporary container that has the volume, and only the changes to the container, not the volume are saved.
您可以尝试要求上游存储库更改其映像，以从Dockerfile中删除卷定义.或者，您可以拉他们的仓库，并在没有卷的情况下构建自己的基础映像版本.这些都不会阻止您稍后在该目录中带有卷的情况下运行容器.
You can try asking the upstream repo to change their image to remove the volume definition from the Dockerfile. Or you can pull their repo and build your own version of the base image without the volume. Neither of these will prevent you from running the container later with a volume in that directory.
否则，如果要扩展图像并使用RUN命令进行更改，则需要将文件保存在另一个目录中.您还可以使用一个入口点，在容器启动时将这些文件复制到/var/www/html.
Otherwise, if you want to extend the image and make changes with RUN commands, you'll need to save your files in another directory. You could also have an entrypoint that copies those files to /var/www/html on container start.
您还可以考虑一个多阶段构建，在第一阶段修复权限，然后在发布阶段将文件直接复制到卷中.如您所见，COPY仍可用于卷.它不是用临时容器实现的，因此可以将文件直接放置在图像文件系统中.
You could also consider a multi stage build, fixing the permissions in the first stage, and then copying the files directly into the volume in the release stage. As you've noticed, COPY still works with volumes. It isn't implement with a temporary container and therefore can place files directly in the image filesystem.
