If you have multiple services running on Docker with different ports, you have to open ports in your firewall and you have to access the services via different ports in the browser. To have one access port (port 80 or 443) you can use a reverse proxy.
In our case we used NGINX to redirect the access to Kibana (Elasticsearch Dashboard Tool) and PgAdmin4 (PostgreSQL Admin Tool) so that we can access both services on the same port (80) in the browser with different base paths: http://localhost/kibana and http://localhost/pgadmin.
