I'm getting a directory index of "/src/" is forbidden error when setting up Docker Nginx configuration within Kubernetes. Here is the error from the Kubernetes logs.

/docker-entrypoint.sh: /docker-entrypoint.d/ is not empty, will attempt to perform configuration

My dockerfile to serve nginx for an Angular app is quite simple:

FROM nginx

RUN rm /etc/nginx/conf.d/default.conf

COPY ./nginx/conf.d /etc/nginx/

COPY dist /src

RUN ls /src

My nginx.conf file contains:

worker_processes  1;

events {
    worker_connections  1024;
}

http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;

    server {
        listen       80;
        server_name 0.0.0.0;
        root   /src;

        charset utf-8;
        include h5bp/basic.conf; # eg https://github.com/h5bp/server-configs-nginx
        include modules/gzip.conf;

        location =/index.html {
            include modules/cors.conf;
        }

        location / {
            try_files $uri$args $uri$args/ /index.html;
        }
    }
}

The Kubernetes deployment is using a Quay image. Do you think my error could be in the dockerfile, the nginx.conf file, or both?
