php - 在docker上运行lumen api时出错(原因:php_network_getaddresses:getaddrinfo失败:名称或服务未知)

Question

我正在尝试在docker(https://github.com/alves-nathan/covidprudente)上运行一个非常简单的lumen api。
构建正常，但是尝试运行镜像将返回错误:

Failed to listen on  localhost:8001 (reason: php_network_getaddresses:
getaddrinfo failed: Name or service not known)

Warning: Unknown: php_network_getaddresses: getaddrinfo failed:
Name or service not known in Unknown on line 0

Dockerfile:

FROM php:7.4-fpm

RUN chmod o+r /etc/resolv.conf

RUN apt-get update && apt-get install -y \
    build-essential \
    libpng-dev \
    libonig-dev \
    libjpeg62-turbo-dev \
    libfreetype6-dev \
    libzip-dev \
    locales \
    zip \
    jpegoptim optipng pngquant gifsicle \
    vim \
    unzip \
    git \
    curl

RUN apt-get clean && rm -rf /var/lib/apt/lists/*

RUN docker-php-ext-install pdo_mysql mbstring zip exif pcntl
RUN docker-php-ext-configure gd --with-freetype --with-jpeg
RUN docker-php-ext-install gd

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

RUN groupadd -g 1000 www
RUN useradd -u 1000 -ms /bin/bash -g www www

ENV HOME=/home/app
COPY ./ $HOME/codivpp/

COPY --chown=www:www ./ $HOME/codivpp/

USER www
WORKDIR $HOME/covidpp

EXPOSE 8001

CMD ["php", "-S localhost:8001 -t public"]

我仍然是docker的初学者，所以我不知道自己缺少什么。

其他(也许)有用的信息:

Docker version 19.03.11, build 42e35e61f3

Answer 1

您需要将localhost添加到您的主机文件。该错误意味着localhost不存在。

另外，我们真的需要查看如何设置您的nginx和docker composer。
