[![License](http://img.shields.io/:license-mit-blue.svg?style=flat-square)](http://badges.mit-license.org) [Gitea](https://gitea.io) is a self-hosted git service written in Go. It provides a setup that is similar to [Github](https://github.com) but a solution that you host yourself. This repository contains the necessary configuration to run a full Gitea service in [Docker](https://docs.docker.com) using [Docker Compose](https://docs.docker.com/compose) and the capability to auto renew SSL certificates with [Let's Encrypt](https://www.letsencrypt.org).

## Requirements
Here are the basic requirements:
* An internet connected server or VPS with a static IP address
- SSH access to the server
- Storage space on the server for the service and repository data
* A domain with an ``A`` record pointing to the server IP (Configured at DNS provider)
Name | TTL | Class | Type | Record
--- | --- | --- | --- | ---
`git.example.com` | `1200` | `IN` | `A` | `$IP`
* An email address (e.g. gitea@example.com) configured at your domain (If you want the Gitea service to be able to send email)
- Make sure to note down the outgoing (SMTP) mail server information (e.g. smtp.example.com:465)
This guide assumes you are using Debian/Ubuntu but it can be adapted to other variations of linux.
If you would like to add additional configuration options or help automate some of the setup see [contributing](#contributing) below.
## Quick start
Install docker and docker-compose.
```
# Install docker
sudo apt-get install docker
# Install docker-compose
sudo curl -L "https://github.com/docker/compose/releases/download/1.25.4/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
# Make docker-compose executable
sudo chmod +x /usr/local/bin/docker-compose
```
Create ``docker`` group and add current user to group (or add the user you would like to run docker).
```
# Create docker group
sudo groupadd docker
# Add user to docker group
sudo usermod -aG docker $USER
```
Setup the [.env](#environment) file for your desired configuration.
```
# Verify that docker service is running
sudo systemctl status docker
# Run a test container
docker run hello-world
# Clone this repository to your computer
git clone https://github.com/bitdexgroup/docker-gitea && cd docker-gitea
# Create a ``.env`` file by copying and adjusting ``env.sample`` for configuration.
cp env.sample .env
# Create required ``CONFIG`` directories
sudo mkdir -p /var/lib/gitea
# Start docker containers
docker-compose up -d
# Verify containers are running
docker ps
```
## Addtional Steps
### Create git user
Create a new ``git`` user on the host machine with UID and GID matching the ``git`` user inside the Gitea container.
```
# Create git user
adduser git
# Make sure user has UID and GID 1000
usermod -u 1000 -g 1000 git
```
### SSH passthrough
Create the file ``/app/gitea/gitea`` with the following contents:
```
#!/bin/sh
ssh -p 2222 -o StrictHostKeyChecking=no git@127.0.0.1 "SSH_ORIGINAL_COMMAND=\"$SSH_ORIGINAL_COMMAND\" $0 $@"
```
Make the file ``/app/gitea/gitea`` excecutable.
`sudo chmod +x /app/gitea/gitea`
Generate an SSH key for the ``git`` user and create a symlink between the container and host ``authorized_keys``.
```
# To generate an RSA key
sudo -u git ssh-keygen -t rsa -b 4096 -C "Gitea Host Key"
```
```
# Alternately, to generate an ED25519 key
sudo -u git ssh-keygen -t ed25519 -C "Gitea Host Key"
```
```
# Create a symlink between container ``authorized_keys`` and host git user ``authorized_keys``
ln -s /var/lib/gitea/git/.ssh/authorized_keys /home/git/.ssh/authorized_keys
```
Echo the ``git`` user key into the ``authorized_keys`` file
```
# For an RSA key
echo "no-port-forwarding,no-X11-forwarding,no-agent-forwarding,no-pty $(cat /home/git/.ssh/id_rsa.pub)" >> /var/lib/gitea/git/.ssh/authorized_keys
```
```
# For an ED25519 key
echo "no-port-forwarding,no-X11-forwarding,no-agent-forwarding,no-pty $(cat /home/git/.ssh/id_ed25519.pub)" >> /var/lib/gitea/git/.ssh/authorized_keys
```
### Installation
The first time you go to the site Gitea will guide you through the installation wizard.
* Enter the email address and password for the Gitea email account
* Enter the correct mail server information.
* Most of the remaining items should stay at the default setting.
## Security
On the host machine, make sure to use a strong user password and strong ssh keys. When you create the gitea administrator for the first time use a strong password as well.
### External ports
If a firewall is configured on the host the following external ports must be opened:
* 80/tcp for Web UI HTTP
* 443/tcp for Web UI HTTPS
* 22/tcp for SSH
On a Debian/Ubuntu server this can be configured using UFW:
```
# Install ufw
sudo apt-get install ufw
# Enable ufw service
sudo systemct enable ufw
# Set ufw default to deny all incoming
sudo ufw default deny incoming
# Set ufw default to allow all outgoing
sudo ufw default allow outgoing
# Set ufw to allow 80/tcp, 443/tcp, and 22/tcp
sudo ufw allow 80/tcp
sudo ufw allow 443/tcp
sudo ufw allow 22/tcp
# Display status of ufw service
sudo ufw status verbose
```
## Configuration
### Environment
The configuration is performed via environment variables contained in a ``.env`` file. You
can copy the provided ``env.sample`` file as a reference.
Variable | Description | Example
--- | --- | ---
`APP_NAME` | Name to display on homepage and tab | Gitea: Git with a cup of tea
`PROTOCOL` | Protocol for Gitea server | (Default: https)
`DOMAIN` | Domain for the Gitea service | git.example.com
`VIRTUAL_HOST` | Virtual host for Gitea server | git.example.com
`VIRTUAL_PORT` | Virtual port for Gitea server to expose to proxy network | 3000
`LETSENCRYPT_DOMAIN` | Domain for which to generate the certificate | git.example.com
`LETSENCRYPT_EMAIL` | E-Mail for receiving important account notifications (mandatory) | admin@example.com
`DB_NAME` | Name for the database | gitea
`DB_USER` | User for the database | gitea
`DB_PASSWD` | Password for the database | gitea

* **gitea**: Gitea, a self-hosted git service written in Go.
* **db**: PostgreSQL, the database for the git server.
### Volumes
Local
* **/var/lib/gitea**: Persistent volume for Gitea data
Named

* **vhost**: Persistent volume for nginx virtual host configuration
* **html**: Persistent volume for nginx html data
* **certs**: Persistent volume for nginx certificate data
* **postgres**: Persistent volume for PostgreSQL database
### Advanced configuration
To make additional configuration changes first shut down the containers with `docker-compose down`
* Edit ``docker-compose.yml`` to update the Docker service
* Edit ``/var/lib/gitea/gitea/conf/app.ini`` to update the Gitea configuration
* Edit ``nginx.tmpl`` to update the Nginx configuration
Restart the containers with `docker-compose up -d`
