docker run command ends up in : nginx: [emerg] unknown directive “events” in /etc/nginx/nginx.conf:1

Question

I have installed nginx-extras from Ubuntu bash shell in my desktop Windows 10 O.S. The is required to spin up a docker container for an ASP.NET Core 3.1 Blazor web assembly application for serving the static web pages. My nginx.conf:

 events { }
   http {
      include mime.types;
      types {
         application/wasm wasm;
       }
     server {
        listen 80;
        index index.html;
        location / {
           root /var/www/web;
           try_files $uri $uri/ /index.html =404;
        }
     }
}

Dockerfile:

FROM mcr.microsoft.com/dotnet/core/sdk:3.1 AS build-env
WORKDIR /app
COPY . ./
RUN dotnet publish -c Release -o output

FROM nginx:alpine
WORKDIR /var/www/web
COPY --from=build-env /app/output/wwwroot .
COPY nginx.conf /etc/nginx/nginx.conf
EXPOSE 80

My build command was successful.

However when I wanted to create a container using the command: docker run -p 8080:80 docker-wasm-blazor It gave me an error:

[emerg] 1#1: unknown directive "events" in /etc/nginx/nginx.conf:1 nginx: [emerg] unknown directive "events" in /etc/nginx/nginx.conf:1

I am very new to nginx and containerisation, so any help will be highly appreciated. Thanks.

I had the same error. Fixed by changing the encoding of the nginx.conf file. If you create the nginx.conf file in/with visual studio (Add -> new File) it's most likely that your will get the wrong encoding (other people got the same error).

In my case the encoding was UTF-8 and I needed us-ascii encoding. The easiest was to delete my nginx.conf file and recreate it outside of visual studio (I used Sublime text but I think you can use notepad).
