php - 如何正确链接 php-fpm 和 Nginx Docker 容器？

Question

我正在尝试链接 2 个单独的容器:

• nginx:latest
• php:fpm

问题是 php 脚本不起作用。可能是 php-fpm 配置不正确。这是源代码，在我的repository .这是文件 docker-compose.yml:

nginx:
    build: .
    ports:
        - "80:80"
        - "443:443"
    volumes:
        - ./:/var/www/test/
    links:
        - fpm
fpm:
    image: php:fpm
    ports:
        - "9000:9000"

和 Dockerfile 用于构建基于 nginx 的自定义镜像:

FROM nginx

# Change Nginx config here...
RUN rm /etc/nginx/conf.d/default.conf
ADD ./default.conf /etc/nginx/conf.d/

最后，这是我自定义的 Nginx 虚拟主机配置:

server {
    listen  80;

    server_name localhost;
    root /var/www/test;

    error_log /var/log/nginx/localhost.error.log;
    access_log /var/log/nginx/localhost.access.log;

    location / {
        # try to serve file directly, fallback to app.php
        try_files $uri /index.php$is_args$args;
    }

    location ~ ^/.+\.php(/|$) {
        fastcgi_pass 192.168.59.103:9000;
        fastcgi_split_path_info ^(.+\.php)(/.*)$;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param HTTPS off;
    }
}

谁能帮我正确配置这些容器以执行 php 脚本？

附言我像这样通过 docker-composer 运行容器:

docker-compose up

来自项目根目录。

我知道这是一篇旧帖子，但我遇到了同样的问题，不明白为什么您的代码不起作用。经过大量测试，我找到了原因。

fpm 似乎从 nginx 接收到完整路径并尝试在 fpm 容器中查找文件，因此它必须与 nginx 配置中的 server.root 完全相同，即使它在 nginx 容器中不存在。

演示:

docker-compose.yml

nginx:
    build: .
    ports:
        - "80:80"
    links:
        - fpm
fpm:
    image: php:fpm
    ports:
        - ":9000"

    # seems like fpm receives the full path from nginx
    # and tries to find the files in this dock, so it must
    # be the same as nginx.root
    volumes:
        - ./:/complex/path/to/files/

/etc/nginx/conf.d/default.conf

server {
    listen  80;

    # this path MUST be exactly as docker-compose.fpm.volumes,
    # even if it doesn't exist in this dock.
    root /complex/path/to/files;

    location / {
        try_files $uri /index.php$is_args$args;
    }

    location ~ ^/.+\.php(/|$) {
        fastcgi_pass fpm:9000;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }
}

Dockerfile

FROM nginx:latest
COPY ./default.conf /etc/nginx/conf.d/
