This is not how people finder is actually deployed but provides an environment to do development on the app.

On a Ubuntu 12.04 LTE box:

• install curl, git, postgresql, postgresql-dev-all, nodejs
• install rails through rvm. One way is:
  • gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3
  • \curl -L https://get.rvm.io | bash -s stable --ruby
• start a new shell
• rvm gemset use global
• gem install bundler
• gem install rails
• clone this repository
• cd peoplefinder
• bundle install
• sudo su postgres createuser ubuntu (or the name of the user the application will be running as)
• createdb peoplefinder_development (as the user the application will be running as)
• bin/rake db:migrate RAILS_ENV=development
• bundle exec rails s -b 0.0.0.0

Point your browser to http://0.0.0.0:3000 and you should see the application's start page.

PeopleFinder uses Ruby 2.3.7 and bundler 1.14.6

Install Ruby 2.3.7 using rbenv or rvm then install bundler using

gem install bundler:1.14.6

PeopleFinder relies on Elasticsearch for its search functionality, and ElasticSearch requires Java to be installed on your Mac. Presently we use Elastisearch 1.7 which requires Java 8.

Oracle recently changed the licensing for Java such that you need to agree to their updated licence agreement before you download it. This in turn has meant that they have broken all previous methods for obtaining older versions of Java, so most of the suggestions that previously worked no longer do. At time of writing (late 2019) the best method is to install OpenJDK using homebrew as follows.

$ brew tap homebrew/cask-versions
$ brew cask install homebrew/cask-versions/adoptopenjdk8

If you need to have other versions of Java installed, you may need to add this to your ~/.bash_profile file or find some other way of switching the active version.

export JAVA_HOME=`/usr/libexec/java_home -v 1.8`

Install Homebrew if it is not on your machine.

Regarding Elasticsearch, unfortunately the version we use is no longer available from Homebrew. The easiest thing to do is run the Elasticsearch server in Docker and keep it running in a separate terminal window for local development use:

docker run --name elasticsearch  --publish 9200:9200 bitnami/elasticsearch:6.8.6-r1

Install remaining dependencies on Mac OSX:

brew install postgresql
brew install imagemagick
brew cask install phantomjs

git clone git@github.com:ministryofjustice/peoplefinder.git
cd peoplefinder

gem install eventmachine -v 1.0.5 -- --with-cppflags=-I/usr/local/opt/openssl/include

# if you encounter issues with the bundler version
# for example if you have a later version installed in this ruby,
# add _1.14.6_ to the following commands e.g.:
# `bundle _1.14.6_`
bundle
bundle exec rake db:setup
bundle exec rake peoplefinder:db:reload # includes demo data
bundle exec rake # runs tests - make sure Elasticsearch is running
bundle exec rails s -b 0.0.0.0

In a separate terminal, run job worker for sending emails:

cd peoplefinder
bundle exec rake jobs:work

To catch emails in development, in a separate terminal, run mailcatcher and view emails at http://localhost:1080:

cd peoplefinder
mailcatcher

These should be defined in the config/application.rb or in the enviroments/environment.rb files if the settings need to be defined on a per environment basis.

config.app_title e.g. 'My New People Finder'

config.default_url_options e.g. { host: mail.peoplefinder.example.com }

config.disable_token_auth Disable the 'token-based authentication' feature

config.elastic_search_url Required for production (see Search section below)

config.ga_tracking_id Google Analytics tracking id [optional]. e.g. 'XXXX-XXX'

config.support_email e.g. '[email protected]'

config.send_reminder_emails Set to true if reminder emails are to be sent by cronjobs

The system allows logging in for emails which have domains from the whitelist. The whitelist is in the database, managed by PermittedDomain model. At least one domain has to be whitelisted before anyone can log in (that applies to development too).

In rails console:

PermittedDomain.create(domain: 'some.domain.gov.uk')

Authentication for Log in to People Finder in the various environments (dev/staging/prod) is handled by the setting of GPLUS_CLIENT_ID and GP_CLIENT_SECRET environment variables in the private People Finder Deployment repo

You can configure your local machine for authentication by obtaining an OAuth Client ID and Secret from google+ and setting them in a .env.local file (.gitignore'd).

To create your own ID and SECRET:

• visit the Google Developers Console.

• Create a project, optionally naming it PeopleFinder-local, and wait for the process to complete.

• Select Google+ API from the central panel "Overview", then hit the Enable button. Wait for process to complete then follow link to Go to Credentials or choose Credentials from left sidebar, then follow the steps required to create an OAuth 2.0 client ID for a Web application.

• On OAuth consent page you can optonally set the Product name to PeopleFinder-local

• On the credentials page:

  • set Application type to Web application
  • set Name to PeopleFinder-local
  • set Authorized JavaScript origins to the root (e.g. http://localhost:3000)
  • set Authorized redirect URIs to the OAuth redirect path, currently http://localhost:3000/auth/gplus/callback, but check routes.rb

Hit create/continue until process is complete and you will receive a client ID and client SECRET.

For local development purposes the ID and SECRET can be stored in your bash profile or you can create an .env.local file based on .env.example and set them, as below.

GPLUS_CLIENT_ID=your_gplus_client_id
GPLUS_CLIENT_SECRET=your_gplus_client_secret

The permitted domains are configured in config/application.rb.

An alternative 'token-based' authentication method is also supported. The token authentication method relies upon the users access to their email account to authenticate them.

Each time the user wishes to start a session, they need to generate an authentication token. This can be done by entering their email address (from a permitted domain) on the login screen. They will be sent an email message containing a link with a unique random token. Clicking on the link will allow them to login.

People Finder sends a few types of e-mail. E-mails are delivered using delayed_job adapter for activejob.

Run bundle exec rake jobs:work to activate the worker.

In production, periodic emails are sent to users that have:

• never logged in before;
• not updated their profile for a period of time; and
• not added a team description when they are a team leader.

Cron jobs are handled using Kubernetes Cron jobs. The files are located in config/kubernetes. These are responsible for Emails like the one that you received when someone updates your profile.

E-mails in development environment are setup to be delivered using mailcatcher gem. For that mailcatcher has to be started and then accessed on http://localhost:1080 to read the delivered e-mails.

To run the engine in production mode, config.elastic_search_url must be set in, for example, config/application.rb. See 'Configurable elements' above.

Heroku provides Bonsai Elasticsearch as an add-on.

You can install a development version from Elasticsearch 1.7.3 downloads or with a package manager. e.g. brew install elasticsearch17.

Elasticsearch requires jdk version 7 or greater.

To check the health of the elasticsearch (ES) stack you can use the following, from either host instance:

curl 'localhost:9200/_cat/health?v'

or view ES settings and stats:

curl 'localhost:9200/_cluster/stats/?pretty'
curl 'localhost:9200/_cat/indices?v'
curl 'localhost:9200/_cat/nodes?v'

If you get an IndexMissingException, you will need to index the Person model:

bundle exec rake environment elasticsearch:import:model CLASS='Person' FORCE=y

Or, alternatively:

rake peoplefinder:es:index_people

Or you can create the index from the console:

Person.__elasticsearch__.create_index! index: Person.index_name, force: true`

And populate it:

Person.import

You can also delete the index:

Person.delete_indexes

To run specs without Elasticsearch:

bundle exec rspec . --tag ~elastic

Manipulation

We use MiniMagick so either Imagemagick or Graphicsmagick need to be installed for image manipulation and for some of the tests.

If using brew you can use the following command:

brew install imagemagick

Storage

For the dev environment the profile images are stored as files in the container and therefore do not persist between container deploys. For the Demo, Staging and Production environments profile images are stored in their own AWS S3 bucket. The buckets do not grant any group permissions to non-AWS users (i.e. are private). Access to the images is achieved via presigned, time-limited urls generated by the app.

Images that are uploaded to the bucket by the app explicitly prevent read to the "Everyone" AWS group using CarrierWave configuration in its initializer - the default for this config is true/public.

config.fog_public = false # default: true

Profile images had originally applied the AWS Canned-ACL public-read, rendering them public, and therefore two rake tasks have been written to assist with amending the Access Control List for image objects.

To make images private (and therefore accessible only via presigned-urls):

rake peoplefinder:S3:privatise_images

To make images available to the "Everyone" AWS group:

rake peoplefinder:S3:publicise_images

You'll need to install PhantomJS in order to run the headless browser tests and the smoke_test.

On OSX:

brew install phantomjs

On a Linux box, you won't find a pre-packaged headless phantomjs as of this writing. You might need to recompile it from source (we have it in a private apt repository).

Also, if you'd like test coverage for Javascript you'll need to have Node and Istanbul installed. The easiest way to do this is installing Node via nvm and then use npm to install Istanbul like so:

npm install -g istanbul

The application layout is set by the moj_internal_template that is installed as part of this engine.

You can override this layout in wrapper application, create your own file:

app/views/layouts/peoplefinder/peoplefinder.html.haml

A lot of the text in the views is configurable in the translations file.

You can override these in wrapper application by creating your own file:

config/locales/en.yml

The RandomGenerator is able to generate several layers of teams and people with randomly generated details in those teams.

Usage:

  group = Group.find(...)

  # initialise the generator with a parent group
  generator = RandomGenerator.new(group)

  # clean all subgroups and people within the provided parent group
  generator.clear

  # generate team structure and people with the given parameters
  groups_levels = 2 # number of levels to generate
  groups_per_level = 3 # how many teams per each level
  people_per_group = 5 # how many people should be in the bottom most teams
  domain = 'fake.gov.uk' # which e-mail address should be used for e-mails (has to be whitelisted)
  generator.generate(groups_levels, groups_per_level, people_per_group, domain)

You can also generate semi-random data using the rake task peoplefinder:data:demo which is called as part of peoplefinder:db:reload. Repeatedly running peoplefinder:demo:data will add members to the example groups it creates.

Run rake -T | grep people for latest list:

rake peoplefinder:data:demo                    # create basic demonstration data
rake peoplefinder:data:demo_csv[count,file]    # create a valid csv for load testing, [count: number of records=500], [file: path to file=spec/fixtures/]
rake peoplefinder:db:clear                     # drop all tables
rake peoplefinder:db:reload                    # drop tables, migrate, seed and populate with demonstration data for development purposes
rake peoplefinder:db:reset_column_information  # reset all column information
rake peoplefinder:import:csv_check[path]       # Check validity of CSV file before import
rake peoplefinder:import:csv_import[path]      # Import valid CSV file

Mail previews can be found at http://localhost:3000/rails/mailers, assuming the server is running locally on port 3000.

A Geckboard dashboard is used for the visualization of various metrics from Peoplefinder. These metrics take the form of either pollable endpoints locate under app/metrics/.. OR pushable/publishable geckboard datasets located under lib/geckoboardpublisher/..

The datasets are scheduled for pushing in Kubernetes Cron Jobs and cron installed on the worker instances (production environment only).

Once published, datasets are wired up on Geckboard by adding a widget, specifying "Datasets" for the connection type and selecting the published dataset from the list available.

For testing purposes you can manually publish reports as below:

GeckboardPublisher::ProfilePercentagesReport.new.publish!

which will, on staging, create a dataset called peoplefinder-staging.profile_percentages_report

and to remove the report...

GeckboardPublisher::ProfilePercentagesReport.new.unpublish!

NOTE: there is a limit of 100 datasets per geckboard account and a limit of 5000 records per dataset. Further, you can only push a maximum of 500 records per request.

A large part of the audience for Peoplefinder are, at time of writing, still reliant on Windows XP for their OS and IE7 for their browser. Consequently considerable styling and javascript needs IE7 workarounds. To assist, you can install Virtual Box VMs using the guide below

1. install virtual box - Virtualbox

2. you can download fairly reliable MS Windows VMs using this site at xdissent. The simplest method is to download the Windows 7 with IE10 VM and use the Developer tools in IE10 to change Browser mode and Document mode to IE7.

   curl -s https://raw.githubusercontent.com/xdissent/ievms/master/ievms.sh | env IEVMS_VERSIONS="10" bash
   

3. once command above has completed power on the machine in virtual box, start IE and use http://10.0.2.2:3000 (i.e. 10.0.2.2 maps to the host's localhost IP)

4. you can map the VMs localhost to 10.0.2.2 to allow GPlus OAuth login to function by amending the hosts file, C:\Windows\System32\drivers\etc\hosts, to add the line below:

10.0.2.2    localhost

• enable host to VM copy/paste

  vbox > machine > settings > General(tab) > Advanced(tab) > Shared clipboard(dropdown) > Bidirectionl
  

CI by Travis.

Software metrics by Code Climate

If the Peoplefinder is to be successful, profiles need to be populated and maintained.
