Unable to upload files > 1mb in Rancher; Nginx returns 413 error code for file sizes >1mb. How to modify configuration to allow for larger uploads?

Question

I am not unable to upload files that are larger than 1mb. Nginx is responding with a 413 when the file size is greater than 1mb in Rancher.

I tried to locate the NGINX configuration in Rancher but I was unable to find it. I checked in the storage section in the Rancher namespace, where the configmaps were but I did not see a data section in that configmap where the nginx.conf would be

If you are using Rancher and you are experiencing an issue where you cannot upload files larger than 1MB, the solution is to increase the client-max-body-size annotation in the Rancher ingress controller.

To do this, follow these steps:

• Go to the Ingress tab in the Rancher UI.
• In the Namespace dropdown, select cattle-system.
• Click on the name of the ingress controller.
• In the Annotations section, click Add.
• In the Key field, enter nginx.ingress.kubernetes.io/client-max-body-size.
• In the Annotations section, click Add.
• In the Key field, enter nginx.ingress.kubernetes.io/client-max-body-size.
• In the Value field, enter a value greater than 1MB. For example, to set the limit to 10MB, enter 10M.
• Click Save.

Once you have completed these steps, you should be able to upload files larger than 1MB.

Additional Information:

• The client-max-body-size annotation sets the maximum size of the request body that the ingress controller will accept.
• The default value for client-max-body-size is 1MB.
• You can set client-max-body-size to 0 to disable the limit.

I hope this helps!
