+# Cgit with gitolite and caddy
+
+## Setup
+
+Install dependencies.
+
+	# apt install cgit python-is-python3 python3-pygments python3-markdown docutils-common groff perl
+
+Make a git user.
+
+	sudo adduser --system --shell /bin/bash --group --disabled-password --home /home/git git
+
+Allow ssh passwordless login.
+
+	usermod -p '*' username
+	
+## Gitolite
+
+Install the [gitolite](https://gitolite.com/gitolite/install.html) package from the repository directly.
+
+### Configuration with cgit
+
+Configuration of gitolite is done by modifying `$HOME/.gitolite.rc`.
+
+To work correctly with cgit, gitweb and cgit configuration options need to work with gitolite.
+
+Change:
+
+	GIT_CONFIG_KEYS  =>  '',
+	
+To:
+
+	GIT_CONFIG_KEYS  =>  '.*',
+
+To have permissions work correctly,
+
+Change:
+
+	UMASK  =>  0077,
+	
+To:
+
+	UMASK  =>  0027,
+	
+In the `ENABLE` field, add gitweb and cgit to the list.
+
+### Usage
+
+Detailed usage of gitolite can be found [here](https://gitolite.com/gitolite/basic-admin.html)
+
+### Repository ignore
+
+After cgit is configured, cgit can be told to ignore a repo with this syntax.
+
+	repo gitolite-admin
+		config cgit.ignore=1
+
+### Adding Hooks to gitolite
+
+This [page](https://gitolite.com/gitolite/cookbook#adding-other-non-update-hooks) details how to add hooks to your repositories.
+
+Example hook that updates a website every git push. Make sure this directory is owned by git.
+
+	#!/bin/sh
+	GIT_WORK_TREE=/desired/website/directory git checkout -f
+	
+	
+## Cgit
+
+### Running cgit with caddy
+
+Install the [fcgiwrap](https://packages.debian.org/bookworm/fcgiwrap) package.
+
+Create a systemd service that wraps cgit with FastCGI.
+
+	# systemctl edit --full --force cgit.service
+	
+<!-- tsk -->
+
+	[Unit]
+	Description=CGI web interface to the Git SCM
+	After=network.target
+	
+	[Service]
+	Type=exec
+	ExecStart=fcgiwrap -f -p "/usr/lib/cgit/cgit.cgi" -s tcp:127.0.0.1:8999
+	
+	[Install]
+	WantedBy=multi-user.target
+	
+<!-- tsk -->
+
+	# systemctl start cgit
+	
+Add cgit configuration to caddy.
+
+	git.joshuayun.com {
+        	handle_path /cgit-css/* {
+        	        root * /usr/share/cgit/
+        	        file_server
+        	}
+
+        	handle {
+        	        reverse_proxy localhost:8999 {
+        	                transport fastcgi {
+        	                        env DOCUMENT_ROOT /usr/lib/cgit/
+        	                        env SCRIPT_FILENAME /usr/lib/cgit/cgit.cgi
+        	                }
+        	        }
+        	}
+	}
+
+
+## Cgit configuration
+
+More detailed documentation can be found on the cgitrc(5) [manual](https://linux.die.net/man/5/cgitrc).
+
+enable-git-config is used to allow for gitweb.* configurations in gitolite, e.g. description, owner.
+
+
+	enable-git-config=1
+
+project-list sets where cgit looks for projects, this list is the one updated by gitolite
+
+	project-list=/home/git/projects.list
+	
+scan-path sets where the actual git repositories live
+
+	scan-path=/home/git/repositories

+### Setup
+
+Create a directory with config.json inside, and make sure that its owner has a uid of 1000.
+
+	mkdir data
+	touch data/config.json
+	# Owned by user ID of Docker container (1000)
+	chown -R 1000 data
+	# all access (for creating json database file data/updates.json)
+	chmod 700 data
+	# read access only
+	chmod 400 data/config.json
+
+Configuration for porkbun in config.json
+
+	{
+	  "settings": [
+	    {
+	      "provider": "porkbun",
+	      "domain": "domain.com",
+	      "host": "@",
+	      "api_key": "PORKBUN SECRET KEY",
+	      "secret_api_key": "PORKBUN API KEY",
+	      "ip_version": "ipv4"
+	    }
+	  ]
+	}
