Environment variable NGINX_MAX_UPLOAD is not working

[sujeetkv]

I have set ENV NGINX_MAX_UPLOAD 8m in my Dockerfile but it seems not working because I am not able to upload more than 1MB content. NGINX rejects request saying - Request Entity Too Large.

I too have had this issue using Docker w/ AWS Elastic Beanstalk. This is what helped me - https://stackoverflow.com/a/61943622

If you are sitting behind a reverse nginx-proxy you also need to take that in to account.
User the custom hostnames to create a file that contains:

client_max_body_size 1g;
