Docker 与 PHP-FPM 和 Nginx - 502 Bad Gateway

Question

我目前正在尝试将 Laravel 应用程序 docker 化，我已成功创建了 Dockerfile 和 docker-compose.yml，其中包含所需的依赖项。但是，我很难让 php-fpm 启动并显示我的应用程序。

Dockerfile

# Set master image
FROM php:8.0-fpm-alpine

# Copy composer.lock and composer.json
COPY composer.lock composer.json /var/www/html/

# Set working directory
WORKDIR /var/www/html

# Install Additional dependencies
RUN apk update && apk add --no-cache \
    build-base shadow vim curl \
    php8 \
    php8-fpm \
    php8-common \
    php8-pdo \
    php8-pdo_mysql \
    php8-mysqli \
    php8-mbstring \
    php8-xml \
    php8-openssl \
    php8-json \
    php8-phar \
    php8-zip \
    php8-gd \
    php8-dom \
    php8-session \
    php8-zlib \
    nodejs \
    npm

# Add and Enable PHP-PDO Extenstions
RUN docker-php-ext-install pdo pdo_mysql
RUN docker-php-ext-enable pdo_mysql

# Install PHP Composer
RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer

# Remove Cache
RUN rm -rf /var/cache/apk/*

# Add UID '1000' to www-data
RUN usermod -u 1000 www-data

# Copy existing application directory permissions
COPY --chown=www-data:www-data . /var/www/html

# Change current user to www
USER www-data

# Install app dependencies
COPY package.json /var/www/html/
RUN npm install
RUN npm run dev

# Expose port 9000 and start php-fpm server
EXPOSE 9000
CMD ["php-fpm"]

docker-compose.yml

version: '3'
services:

我在做什么？我正在 MacBook 上运行 Docker，并希望将其部署到生产 Debian 机器上。

我对 docker 还很陌生，所以如果我遗漏了什么，请原谅。

解决了，原来我需要将 php 位置更改为。

    location ~ \.php$ {
        fastcgi_split_path_info  ^(.+\.php)(/.+)$;
        fastcgi_index            index.php;
        fastcgi_pass             app:9000;
        include                  fastcgi_params;
        fastcgi_param   PATH_INFO       $fastcgi_path_info;
        fastcgi_param   SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }
