A Simple Configuration to Host Static Files with Alpine Nginx

In the end, I decided to overwrite the original nginx.conf.

Dockerfile

FROM alpine:3.16

RUN apk --no-cache add nginx

COPY nginx.conf /etc/nginx/nginx.conf
COPY html /var/www/localhost/htdocs

EXPOSE 80
CMD ["/usr/sbin/nginx", "-g", "daemon off;"]

nginx.conf

# /etc/nginx/nginx.conf
user nginx;
# worker_processes auto;
worker_processes 1;

pcre_jit on;
error_log /dev/stderr warn;

events {
 worker_connections 128;
}

http {
  include /etc/nginx/mime.types;
  default_type application/octet-stream;
  server_tokens off;
  client_max_body_size 1m;
  sendfile on;
  tcp_nopush on;
  gzip_vary on;
  map $http_upgrade $connection_upgrade {
    default upgrade;
    '' close;
  }
  log_format main '$remote_addr - $remote_user [$time_local] "$request" '
  '$status $body_bytes_sent "$http_referer" '
  '"$http_user_agent" "$http_x_forwarded_for"';
  access_log /dev/stdout main;

  server {
    root /var/www/localhost/htdocs;
  }
}
