nci standalone server with web ui tutorial

In this tutorial we will setting up continuous integration server powered by leveldb (leveldown package) with web interface (classic ui plugin) which will serve all required static files by it self (static server plugin). We will use yaml (yaml reader plugin) for configure server and projects. Running app will be controlled by forever to get restarted in case of unexpected failure.

We will also use following plugins:

Installation

Please check system requirements section at main nci readme first.

All actions below should be executed from a single user. Root privileges is not required. You better to create separate user when using it on production.

When use local executor all commands running during any project build will be running from this user. This user must have access (and have them in PATH) to node, npm, git and hg commands and also to all commands which used in project build steps.

Create and go to into nci root dir (you can choose any other dir):

mkdir ~/nci && cd ~/nci

install all required packages from npm:

npm install nci nci-classic-ui nci-mail-notification nci-projects-reloader nci-rest-api-server nci-scheduler nci-static-server nci-yaml-reader leveldown forever

create data and projects dirs:

mkdir data data/projects

Configure server

create data/preload.json (to apply yaml reader for server config):

{
    "plugins": ["nci-yaml-reader"]
}

create server config data/config.yaml:

plugins:
    - nci-projects-reloader
    - nci-static-server
    - nci-rest-api-server
    - nci-mail-notification
    - nci-scheduler
    #ui better be last plugin
    - nci-classic-ui

nodes:
    - type: local
      #allow maximum 3 parallel builds
      maxExecutorsCount: 3

http:
    host: 127.0.0.1
    port: 3000
    url: http://127.0.0.1:3000

    static:
        #this settings will be consumed by static server plugin 
        locations:
            #serve static for ui plugin
            - url: /favicon.ico
              root: node_modules/nci-classic-ui/static/
            - url: !!js/regexp ^/(js|css|fonts|images)/
              root: node_modules/nci-classic-ui/static/
            #serve project workspaces via http, remove lines
            #below if don`t need/want that
            - url: !!js/regexp ^/projects/(\w|-)+/workspace/
              root: data/

storage:
    #use leveldown as db backend
    backend: leveldown


notify:
    #configure account for sending notifications
    #this settings will be consumed by mail notification plugin
    mail:
        host: smtp.gmail.com
        port: 587
        auth:
            user: [email protected]
            pass: your_sender_password

Configure projects

Now we can add some projects for building them.

Let's add nci itself as project.

Create project dir first:

mkdir data/projects/nci

then create project config data/projects/nci/config.yaml:

scm:
    type: git
    repository: https://github.com/node-ci/nci
    rev: master

buildEvery:
    #build project every 5 minutes
    time: "0 */5 * * * *"
    #but only if there is scm changes
    withScmChangesOnly: true

#notify when build fails or build status changes (according to previous status)
notify:
    on:
        - error
        - change
    to:
        mail:
            - [email protected]

steps:
    - name: sync deps
      cmd: npm install && npm prune

    - name: test
      cmd: npm test

Usage

Start the server:

node_modules/.bin/forever start -l `pwd`/app.log -a node_modules/.bin/nci

see app.log it should end with something similar to:


[Sun, 31 Jan 2016 19:54:22 GMT] [app] Load plugin "nci-mail-notification"
[Sun, 31 Jan 2016 19:54:22 GMT] [app] Load plugin "nci-scheduler"
[Sun, 31 Jan 2016 19:54:22 GMT] [app] Load plugin "nci-classic-ui"
[Sun, 31 Jan 2016 19:54:23 GMT] [app] Loaded projects:  [ 'nci' ]
[Sun, 31 Jan 2016 19:54:23 GMT] [app] Start http server on 127.0.0.1:3000

Setup completed, now you can use all functions, e.g.:

  • explore web interface by navigate to http://127.0.0.1:3000 in browser
  • trigger project build via curl, e.g. curl http://127.0.0.1:3000/api/0.1/builds -d '{"project": "nci"}'
  • edit/add projects configs in your favourite editor - they should be reloaded automatically

Notes:

  • only projects configs loaded/reloaded automatically, not server. So you should manually restart server to apply serve config changes.
  • do not remove, rename projects on disk. Currently you can do that via rest api, see rest api server plugin
  • if something went wrong please check app.log first
