.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.

Solution

  • 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;
