Crafty

Crafty is a dead simple but useful for personal projects CI server.

Kritika Analysis Status

Screencast1

Features

  • event driven single threaded server
  • dynamic workers (inproc, fork or detach mode)
  • realtime updates
  • realtime log tails
  • REST API
  • integrations with GitHub, GitLab and BitBucket
  • authentication

Demo

Working demo is available at http://crafty.uptosmth.com.

Configuration (YAML)

For default configuration see data/config.yml.example in this repository.

---
access:
    mode: public
    users:
        - username: admin
          password: ab7762952be439c958a7398492a6a3706117e61a217e0e
          hashing: bcrypt
pool:
    workers: 2
    mode: detach
projects:
    - id: app
      build:
          - sleep 10

Configuration file is validated against Kwalify schema schema/config.yml.

Authentication

Two modes are available: public and private. The first one public mode means that anonymous users can browse the crafty server but cannot do any modifying operations like restarting, canceling etc. The private mode will not accept not logged in users.

Hashing passwords

A special utility util/hash-password.pl is provided to make hashing password easier. For example we want to create a user admin with password pa$$w0rd using bcrypt hashing algorithm and salt thisismysalt:

$ bin/env util/hash-password.pl --hashing bcrypt --salt thisismysalt admin pa$$w0rd
username: admin
password: 1e52bcc68f3eef5eb9c9a116a678e81dcf7ffa659454dc
hashing: bcrypt
salt: thisismysalt

Put the output into access.users section of the config file.

Installation

Docker

Using existing image

From Docker Hub.

Pull image
$ docker pull vtivti/crafty

Prepare directories
$ mkdir -p crafty/data
$ cd crafty

Prepare config file
$ curl 'https://raw.githubusercontent.com/vti/crafty/master/data/config.yml.example' > data/config.yml

Start container
$ docker run -d --restart always -v $PWD/data/:/opt/crafty/data -p 5000:5000 --name crafty crafty

Build your own image

$ git clone https://github.com/vti/crafty
$ cd crafty
$ sh util/docker-build.sh

From scratch

You have to have Perl 🐫 and SQLite3 installed.

Clone
$ git clone https://github.com/vti/crafty
$ cd crafty

Bootstrap
$ bin/bootstrap

or try fast bootstrap (this can be faster, but still experimental)
$ bin/bootstrap-fast

Run migrations (if any)
$ bin/migrate

Starting

$ bin/crafty
$ bin/crafty --listen :8888
$ bin/crafty --config data/config.yml

Integrations

Integrations are possible on both the incoming webhook and outgoing posthook. Examples can be found in examples directory.

Example GitHub Integration

We are going to integrate incoming webhooks and commit status updates.

  1. Generating personal token

Navigate to https://github.com/settings/tokens and create a personal token with repo:status permission.

  1. Configuring Crafty
---
projects:
    - id: test
      webhooks:
          - id: github
            cgi: github-webhook.sh
      build:
          - git clone http://github.com/vti/test
      post:
          - github-create-status.sh

Adjust github-create-status.sh by putting your token inside.

  1. Creating webhook

Create the webhook on GitHub with the following url pattern:

http://crafty.address/webhook/:webhook_id/:project_id

In our case:

http://crafty.address/webhook/github/test
  1. Push to your repository and check the crafty logs.

REST API

Essentials

Authentication

Basic authentication is used. The username and password are loaded from the config:

access:
    users:
       - username: api
         password: ab7762952be439c958a7398492a6a3706117e61a217e0e
         hashing: bcrypt

Example:

curl http://api:password@localhost:5000/api/builds
