Grafana and nginx reverse proxy with docker

To access grafana via domain name we need to do below configuration on server.

We have to upstream the Grafana in Nginx.conf file as below:

upstream grafana {
  server 10.20.0.90:3000;
}

server {
  location /grafana {
    proxy_pass http://grafana;
  
    
  }
}

And in docker-compose.yml file we have to add root url as below

  grafana:
    #...
    environment:
      - GF_SERVER_ROOT_URL=https://mydomain.com/grafana

To append the grafana external url with the Nginx then you have to add below entries in grafana block in Nginx.conf file

         rewrite  ^/grafana/(.*)  /$1 break;
         proxy_set_header X-Forwarded-Server $host;
         proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
         include proxy_params;
         proxy_set_header Host $host;
