To run Flower behind a reverse proxy, remember to set the correct Host header to the request to make sure Flower can generate correct URLs. The following is a minimal nginx configuration:
server {
listen 80;
server_name flower.example.com;
charset utf-8;
location / {
proxy_pass http://localhost:5555;
proxy_set_header Host $host;
proxy_redirect off;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
}
}
Note that you should not expose this site to the public internet without any sort of authentication! If you have a htpasswd file with user credentials you can make nginx use this file by adding the following lines to the location block:
auth_basic "Restricted";
auth_basic_user_file htpasswd;
