# Ansible role gitea - Install a gitea server
[![Build Status](https://travis-ci.org/thomas-maurice/ansible-role-gitea.svg?branch=master)](https://travis-ci.org/thomas-maurice/ansible-role-gitea)

This role installs and manages a [gitea](https://gitea.io) server -
[Source code & screenshots](https://github.com/go-gitea/gitea).

Gitea is a Golang Git repository webapp, having the same look and feel as GitHub.

It is still under developpement, see "Disclaimer" if you can't make it work.

## Sample example of use in a playbook

The following have been tested with Debian 8, it should work on Ubuntu as well.

```yaml
- name: "Install gitea"
  hosts: all
  vars:
    gitea_user: "gitea"
    gitea_home: "/var/lib/gitea"
    # To limit your users to 30 repos
    gitea_user_repo_limit: 30
    # Not to make use of any CDN
    gitea_offline_mode: true

    # Some 'rendering' options for your URLs
    gitea_http_domain: git.yourdomain.fr
    gitea_root_url: https://git.yourdomain.fr

    # Here we assume we are behind a reverse proxy that will
    # handle https for us, so we bind on localhost:3000 using HTTP
    gitea_protocol: http
    gitea_http_listen: 127.0.0.1
    gitea_http_port: 3000

    # SSH server configuration
    gitea_ssh_listen: 0.0.0.0
    gitea_ssh_port: 2222
    # For URLs rendering again
    gitea_ssh_domain: git.yourdomain.fr
    gitea_start_ssh: true

    gitea_secret_key: 3sp00ky5me
    gitea_disable_gravatar: true
    # To make at least your first user register
    gitea_disable_registration: false
    gitea_require_signin: true
    gitea_enable_captcha: true

    gitea_show_user_email: false
  roles:
    - gitea
```

## Disclaimer
This module is currently a work in progress. For now it is only able to install
gitea from the Github Release, in a fixed version for Linux amd64, on systems
using systemd.

This said, it should work on every major Linux distribution, it has been tested
successfully on Debian Jessie 64 bits.

## Contributing
Do not hesitate to make me a pull request, and when in doubt you can reach me on
Twitter [@thomas_maurice](https://twitter.com/thomas_maurice).

I also would be happy to fix the issues that would be opened, or even better, review
your pull requests :)

## Testing
Testing uses [molecule](https://molecule.readthedocs.io/en/stable-1.22/usage.html), to start the
tests, install the dependencies, I would recommend you use a virtual env for that but who am I to
tell you what to do.

```
pip install pew # install pew to manage the venvs
pew new ansible # create the venv
pip install -r requirements-travis.txt # install the requirements
molecule test # Run the actual tests
```

Note: you need Docker installed

### Known testing limitations
As of now, it is mainly validating that the playbook runs, the lint is ok and that type of things,
since it runs in Docker we have no way yet to check if the service actually is launched by systemd
and so on, this has to be worked on.
