README.md

These scripts will manage the sym link's for a given nginx vhost app and it's upstreams based on the arguments provided.

How to use

1. To enable, run script ./enable.sh app_name [app_domain_name]
2. To disable, run script ./disable.sh app_name [app_domain_name]

Arguments

ARGUMENT	DESCRIPTION
app_name	the name of the app, it should match the sub domain and before the _upstream for the upstream.
app_domain_name	optional and defaults to domain.com

Running ./enable.sh img will create two symlinks

1. /etc/nginx/upstreams-enabled/img_upstream.conf
2. /etc/nginx/sites-enabled/img.domain.com

Running ./disable.sh img will remove two symlinks

1. /etc/nginx/upstreams-enabled/img_upstream.conf
2. /etc/nginx/sites-enabled/img.domain.com

disable.sh

#!/bin/bash

# Get the first argument (APP_NAME)

# Get the second argument (DOMAIN_NAME) or default to "domain.com"

# Define paths for upstream and site configuration files

SITE_ENABLED="/etc/nginx/sites-enabled/${APP_NAME}.${DOMAIN_NAME}"

# Check if the upstream symlink exists
