Ionic build in Docker container with nginx

Question

I was playing around with Ionic the last couple of days and now i want to deploy my website in a Docker Container with nginx on it.

But there is a problem with the Routing: If i type in the IP-Adress of my server with the port (e.g.: http://10.0.0.1/) I will directly redirected to the Dashboard (http://10.0.0.1/dashboard).

As far so good: But if I press F5 in the Dashboard tab I get an 404 Not Found error.

I already read lots of Stackoverflow articles about this, the most of them say to change the nginx config. So here is my config:

user  nginx;
worker_processes  1;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    gzip  on;

    include /etc/nginx/conf.d/*.conf;

    server {
        listen 80;
        listen 443 default_server ssl;
        server_name  localhost;
        ssl_certificate /etc/nginx/fullchain.pem;
        ssl_certificate_key /etc/nginx/privkey.pem;

        root /usr/share/nginx/html;

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

        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   /usr/share/nginx/html;
        index       index.html;
        }

    }
}
