# Nginx cluster configurator - ncc

Manages the local nginx configuration and replicates changes to a backup.

## Features

* Allows the editing of services and using a template for new ones. Makes sure
  the configuration is valid before reloading the cluster (nginx).
* Automatically obtains SSL certificates and replicates them to the cluster (dehydrated).
* Will only make changes on the master server (keepalived).

# TODO

* Prepare config templates for nginx and dehydrated?
* document dhparam.pem generation (`openssl dhparam -out ssl-dhparams.pem 4096` in /etc/autossl)
* Limit current SSH keys to only config rsync and nginx reload
* Write down how it works in human language
* Create a guide how to use it to intrawiki
* Teach everybody how to use it...

# Build

Run `build.sh` on a linux(-ish) machine. The output is a tarball `ncc.tar`.

# Installation

* Extract `ncc.tar` to a location on the server
* Copy configuration `config` to `/etc/ncc` and modify to suit your environment
* Add `/etc/ncc/ncc-hook.sh` as a hook to your `dehydrated` installation
* Add `ncc` to your `PATH`
* Optionally add shell completion:
    * Bash: `_NCC_COMPLETE=bash_source ncc > /etc/bash_completion.d/ncc && . /etc/bash_completion.d/ncc`
