MoJ People Finder

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 3.2.2 and bundler 2.4.19

Install Ruby 3.2.2 using rbenv or rvm then install bundler using

gem install bundler:2.4.19

Install Homebrew if it is not on your machine.

Install opensearch through brew (opensearch is an open source version of elasticsearch)

brew install opensearch

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 Opensearch 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

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.open_search_url Required for production (see Search section below)

config.support_email e.g. 'peoplefinder-support@example.com'

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).

Adding a new domain to the production database from bash/zsh etc:

1. Log into the pod kubectl get pods -n <NAMESPACE>
2. Access the live pod shell kubectl exec -it <POD> -n <NAMESPACE> ash
3. Access rails console from within the shell - rails c
4. Use the following command to create the new domain.
   • Example: PermittedDomain.create(domain: '<DOMAIN_NAME>')
5. To test the domain has worked, visit the live app url. Attempt to sign in with the new domain:
   • Example: email@<DOMAIN_NAME>
6. If successful, you should be navigated to a page which states 'Link sent - check your email'

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.

For local testing - There are a few ways you can get the token

1. Search your token from local development database

 select * from tokens where user_email = <the email you use for asking token from app> order by id desc;

http://localhost:3000/tokens/

2. you can view the server logs and copy the token from there, then paste it into the URL. See the image below:

Then use the token on this URL: http://localhost:3000/tokens/3da4f4e2-8001-4437-b3ab-7e2b3f6e768c <-- replace with your token.3

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.

To run the engine in production mode, config.open_search_url must be set in, for example, config/application.rb. The environment variable used to set it is MOJ_PF_ES_URL See 'Configurable elements' above.

Use localhost:9200 when calling OpenSearch search locally.

The following commands on kubernetes environments will call the open search proxy pod, which will then call open search on AWS to read or update data.

To check the health of the opensearch stack you can use the following, from either host instance. wget will download the information onto the pods so you can read the files using cat. Locally you can just use curl.

wget 'aws-es-proxy-service:9200/_cat/health?v'

or view ES settings and stats:

wget 'aws-es-proxy-service:9200/_cluster/stats/?pretty'
wget 'aws-es-proxy-service:9200/_cat/indices?v'
wget 'aws-es-proxy-service:9200/_cat/nodes?v'

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

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

Or, alternatively:

rake peoplefinder:es:index_people

Or you can create the index from the console if the above rake commands fail:

OpenSearch::Model.client = OpenSearch::Client.new(url: Rails.configuration.open_search_url).index(index: Person.index_name, body: {})
Person.__opensearch__.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 OpenSearch:

bundle exec rspec . --tag ~opensearch

If your shell is Zsh, you have to escape ~ by using \~.

Note: Unfortunately, at the moment there is no way to avoid having ES running locally, but you can use a docker container as mentioned above.

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 local dev environment the profile images are stored as files. For the deployed 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

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 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.

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

###Support

A support email address is set as SUPPORT_EMAIL.

There should be absolutely no secure credentials committed in this repo. Information about secret management can be found in the related confluence pages.

if you want to check/debug prometheus_exporter under local development environment, just open a separated terminial and get into this project root foler and run the following command from command line

>prometheus_exporter

and also comment out the line for checking Rails.env from puma.rb and prometheus_exporter.rb temporarily
