Nginx reverse proxy for grafana using dashboard as subpath

Question

I would like to use dashboard as my nginx location for my grafana install.

The problems is grafana uses dashboard in some of it url's like https://example.com/grafana/dashboard/new?orgId=1, where I would like it to be https://example.com/dashboard/dashboard/new?orgId=1 and I think my nginx location is rewriting to https://example.com/dashboard/new?orgId=1.

When I have it setup to use grafana as the subpath it all work as expected;

grafana.ini:

[server]
http_addr = 127.0.0.1
domain = example.com
root_url = %(protocol)s://%(domain)s/grafana/

nginx config:

# Upstream Servers
upstream grafana_server {
    server localhost:3000;
}

server {
    listen 80;
    listen [::]:80;

    server_name example.com www.example.com;

    return 301 https://$host$request_uri;
}

server {
    listen 443 ssl default_server;
    listen [::]:443 ssl default_server;

    include snippets/ssl-example.com.conf;
    include snippets/ssl-params.conf;

    root /var/www/example.com/html;

    index index.html index.htm;

    server_name example.com www.example.com;

    location /grafana/ {
        proxy_pass http://grafana_server/;
        proxy_set_header Host $host;
    }
}

But changing it to dashboard and navigating to https://example.com/dashboard/dashboard/new?orgId=1 results in the url been rewritten to https://example.com/dashboard/new?orgId=1

grafana.ini:

[server]
http_addr = 127.0.0.1
domain = example.com
root_url = %(protocol)s://%(domain)s/dashboard/

nginx config:

# Upstream Servers
upstream grafana_server {
    server localhost:3000;
}

server {
    listen 80;
    listen [::]:80;

    server_name example.com www.example.com;

    return 301 https://$host$request_uri;
}

server {
    listen 443 ssl default_server;
    listen [::]:443 ssl default_server;

    include snippets/ssl-example.com.conf;
    include snippets/ssl-params.conf;

    root /var/www/example.com/html;

    index index.html index.htm;

    server_name example.com www.example.com;

    location /dashboard/ {
        proxy_pass http://grafana_server/;
        proxy_set_header Host $host;
    }
}

so I have tried a to do a rewrite in the nginx location but can't get it to work as required (really have no clue what to do here)

location ~ (\/dashboard\/) {
    proxy_pass http://grafana_server$1;
    proxy_set_header Host $host;
}

location ~ /dashboard/ {
    rewrite ^ /dashboard/$1;
    proxy_pass http://grafana_server;
    proxy_set_header Host $host;
}

Any help would be much appreciated.

I know this is a bit late - but I stumbled upon the same issue and thought I'd going to share in case somebody else hits this thread:

This isn't an issue with nginx, but with grafana itself.

I could not solve it any other way but renaming the last part of the root_url in something different than /dashboard
