Adjust the default request body size limit for services

[jvstme]

Problem

Many file uploads don't work with services behind dstack-gateway because of the 1MB request body size limit.

Solution

Make the limit less strict. For instance, Apache httpd defaults to 1GB.

See the client_max_body_size Nginx configuration option.

Workaround

Instruct the users to update Nginx configs manually.
