Views.Net 5 AWS nginx Linux elastic beanstalk changing client_max_body_size
I am unable to upload a file above 1 megabyte due to the default setting on AWS elastic beanstalk nginx. I have looked online and I have found out that I need to change the client_max_body_size to client_max_body_size 20M to allow for larger files. However, there is no where for me to do this. There is no Nginx config file on .net. I am using .net 5 and I then use aws toolkit on visual studio 19 to upload it to elastic beanstalk. the only config file that I can see is the aws-beanstalk-tools-defaults.json.

Since you are using 64bit Amazon Linux 2 v2.1.5 running .NET Core nginx is on by default. Thus, I don't see any reason why standard way of customizing nginx wouldn't work for you.
Specifically, the custom settings should be in .platform/nginx/conf.d/ as shown in the docs. Therefore, you can create the following .platform/nginx/conf.d/myconfig.conf file with the content:
client_max_body_size 20M;

This has been achieved before with AWS elastic beanstalk. Although your image may be different, I used the following process:
- Add a folder at the root of your solution and name it '.ebextensions'
- Inside that folder, add a new file and name it '01_nginx.config'
- Update the contents of the file to the following
In a similar solution I worked on, it looked like this:
files:
"/etc/nginx/conf.d/01_proxy.conf":
mode: "000644"
owner: root
group: root
content: |
client_max_body_size 20M;
When you deploy the change to elastic beanstalk, it will read from the ebextensions folder and apply all file updates.
