When i'm running sudo docker-compose up
inside my dir, i get this error.当我在目录中运行
sudo docker-compose up
,出现此错误。 I'm trying to make a container, that host a php website, where you can do whoami on it.我正在尝试制作一个容器,该容器托管一个 php 网站,您可以在其中执行 whoami。 Thanks
谢谢

There's a long-standing general rule in Unix-like operating systems that only the root user can open "low" ports 0-1023.在类 Unix 操作系统中有一个长期存在的一般规则,即只有 root 用户才能打开“低”端口 0-1023。 Since you're trying to run Apache on the default HTTP port 80, but you're running it as a non-root user, you're getting the "permission denied" error you see.
由于您尝试在默认 HTTP 端口 80 上运行 Apache,但您以非 root 用户身份运行它,因此您会看到“权限被拒绝”错误。
The absolute easiest answer here is to use a prebuilt image that has PHP and Apache preinstalled.这里最简单的答案是使用预先安装了 PHP 和 Apache 的预构建映像。 The Docker Hub
php
image includes a variant of this. Docker Hub
php
镜像包含一个变体。 You can use a simpler Dockerfile:您可以使用更简单的 Dockerfile:
FROM php:7.4-apache
# Has Apache, mod-php preinstalled and a correct CMD already,
# so the only thing you need to do is
COPY source /var/www/html
# If you want to run as a non-root user, you can specify
RUN useradd -r -U cp
ENV APACHE_RUN_USER cp
ENV APACHE_RUN_GROUP cp
With the matching docker-compose.yml
使用匹配
docker-compose.yml
version: '3' # version 2 vs 3 doesn't really matter
services:
filebrowser:
build: .
ports:
- '8000:80'
volumes:
- ./logs:/var/log/apache2
If you want to build things up from scratch, the next easiest option would be the Apache User directive: have your container start as root (so it can bind to port 80) but then instruct Apache to switch to the unprivileged user once it's started up.如果你想从头开始构建,下一个最简单的选择是 Apache User指令:让你的容器以 root 身份启动(这样它可以绑定到端口 80),然后在启动后指示 Apache 切换到非特权用户. The standard
php:...-apache
image has an option to do this on its own which I've shown above.标准
php:...-apache
图像有一个选项可以自行执行此操作,我已在上面显示。
