how to clear the docker nginx file cache

I have a nginx running in docker as a static server. When I update the server side folder template.xlsx file. the download still return the old file, I am sure I have replace the static template.xlsx file to a new one. how to make the nginx return the new nginx file? this is the static nginx config:

    listen 443 ssl;

    ssl_certificate /etc/nginx/conf.d/cert/;
    ssl_certificate_key /etc/nginx/conf.d/cert/;


    location / {
        root /usr/share/nginx/html/static;
        client_max_body_size 50m;
        proxy_redirect off;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

        add_header Access-Control-Allow-Origin *;
        add_header Access-Control-Allow-Methods 'GET, POST, OPTIONS';
        add_header Access-Control-Allow-Headers 'DNT,X-Mx-ReqToken,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Authorization';

        index index.html index.htm;

I tried to restart the docker container seems still did not return the new template.
