Docker Nginx Proxy
A basic reverse proxy designed to simplify header manipulation.
Usage
To configure the upstream, create an app.conf with a server block:
server {
listen 8080;
location / {
proxy_pass http://app:80;
}
}The file must be placed in /etc/nginx.
Header manipulation
Within the server block you can maniplate headers using the headers-more module:
server {
...
# Remove a header
more_clear_headers "Server";
# Set a header
more_set_headers 'X-Robots-Tag: "noindex, nofollow"';
...
}Further customisation
Since you're defining a standard server block, you can configure it however you like over and above just header manipulation. For example, you can add a custom location:
server {
...
# Use the default robots.txt to disallow all bots
location /robots.txt {
alias /etc/nginx/robots.txt;
}
...
}Logging
To change how logging is configured, mount a file at /etc/nginx/log.conf:
access_log off;
error_log off;Core configuration
It's also possible to modify core configuration such as those in the main section by mounting a file at /etc/nginx/main.conf:
worker_processes auto;
worker_shutdown_timeout 300s;It's important to note that overriding this file will remove the current defaults hence it's always a good idea to start with a copy of the defaults.
Health check
A health check is available on port 18081 at /healthz.
