I’m using Rancher 2.0.2 setup with a Load Balancer to perform SSL termination/reverse proxying. Functionally it seems to work until I try to upload a large file (~13MB) to a Flask webserver being hosted in a container behind the ingress controller.
The error I get after ~20 seconds of trying to upload the file is:
413 Request Entity Too Large
From looking through the docs and forums, this error looks to be caused by the default nginx setting for client_max_body_size being set to 1M. On a normal nginx setup, I could just go update /etc/nginx/nginx.conf and add/update this parameter. How can I do this for the Rancher 2.0 load balancer ingress controller?
For reference, I have this same workload image running the Flask webserver behind a Rancher 2.0.0-alpha9 deployment (it might use ha proxy for load balancing and ssl termination instead?) and do not see this issue.
