sudo rm -rf /opt/Postman

Step 2

Directories on host machine:

/data/certbot/letsencrypt
/data/certbot/www
Nginx server in docker container

docker run -d --name nginx \

Nginx FastCGI response buffer sizes

By default when Nginx starts receiving a response from a FastCGI backend (such as PHP-FPM) it will buffer the response in memory before delivering it to the client. Any response larger than the set buffer size is saved to a temporary file on disk.

This process is outlined at the Nginx ngx_http_fastcgi_module page manual page.
