Saya telah mencipta 2 penempatan Kubernetes untuk bekas laravel nginx dan php-fpm. Tetapi atas sebab tertentu lalu lintas dari nginx nampaknya tidak berjaya mencapai bekas php-fpm dan menghasilkan ralat berikut

172.18.0.1 - - [18/Jul/2022:16:51:10 +0000] "GET / HTTP/1.1" 404 555 "-" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/100.0.4896.127 Safari/537.36"

Ini ialah fail penempatan saya

Dan api-web部署中用于生成镜像api-web:0.9.4-alphaDockerfile adalah seperti berikut

FROM php:7.2-fpm

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

# Set working directory
WORKDIR /var/www/html

# Install dependencies
RUN apt-get update && apt-get install -y 
    build-essential

    locales 
    zip 
    jpegoptim optipng pngquant gifsicle 
    vim 
    unzip 
    git 
    curl 
    nodejs 
    npm

# Change current user to www

## Run composer dependencies

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

Fail Docker ini juga berfungsi dengan baik tanpa sebarang masalah. docker-compose fail menggunakan imej ini juga akan berfungsi dengan baik.

Sebarang idea mengapa ia datang dari nginx-deployment 容器的流量无法到达 api-web bekas php-fpm dan mendapat ralat
