I created a docker image to server PHP code based on nginx. Everything seems to work quite well except that my request URL always needs to contain index.php (like: http://myserver.com/inde.php). If I skip “index.php” nginx will deliver just the welcome page and not automatically use index.php.

My Dockerfile

FROM alpine:3.16.2
RUN apk update && apk upgrade
RUN apk add --no-cache 
    bash 
    php8  
    php8-fpm  
    php8-json

    php8-pdo_mysql 
    php8-pdo_pgsql 
    php8-pdo_sqlite 
    libmcrypt-dev 
    libltdl 

RUN apk add openssl curl ca-certificates

RUN printf "%s%s%sn" 
"http://nginx.org/packages/alpine/v" 
`egrep -o '^[0-9]+.[0-9]+' /etc/alpine-release` 
"/main" 
| tee -a /etc/apk/repositories

RUN curl -o /tmp/nginx_signing.rsa.pub https://nginx.org/keys/nginx_signing.rsa.pub
RUN openssl rsa -pubin -in /tmp/nginx_signing.rsa.pub -text -noout
RUN mv /tmp/nginx_signing.rsa.pub /etc/apk/keys/
RUN apk add nginx
COPY ./default.conf /etc/nginx/conf.d/default.conf

EXPOSE 80
EXPOSE 443
STOPSIGNAL SIGTERM
CMD ["/bin/bash", "-c", "php-fpm8 && chmod 755 /usr/share/nginx/html/* && nginx -g 'daemon off;'"]

My default.conf:

server {

    listen *:80;
    index index.php index.html;
    server_name myserver;

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

    root /usr/share/nginx/html;

    location / {
        try_files $uri $uri/ /index.php?$query_string;
        # gzip_static on;
    }

    location ~ .php$ {
        try_files $uri =404;
        fastcgi_split_path_info ^(.+.php)(/.+)$;
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param PATH_INFO $fastcgi_path_info;
    }

}

Any idea what I need to fix in my setup to directly get the index.php delivered when requesting http://myserver.com?
