This articles describes how to setup the Maestrano Hub component using the Nex!™ Platform as a Service.

1 - Prerequisites

This documentation is tailored to be used with Maestrano Paas Nex!™.

You need first to have a github account inside the organization allowed by the Nex!™ installation.
Generate your Nex! Api key by accessing the Nex!™ url and allowing the application.
Install Nex! Cli

# install nex_client
gem install nex_client

# Set authentication
export NEX_API_KEY= <your nex! api key>
export NEX_ENDPOINT=<URL of your next! application for example https://nex.yourdomain.io>

# Display all available commands
nex-cli --help

2 - Configuration

Create a configuration file based to set the environment variables, eg: application.mno-hub

Do not check this file into version control!

Update the value according to your configuration

application.mno-hub

3 - Nex!™ - Deploying the app

2.1 - Create the app

Create the App

# Create the app, with the correct environment variable
# Adjust the tags and description based on the environment you are deploying to
nex-cli apps:create maestrano/web-jruby --env-file <path/to/application.mno-hub>  --size 20 --tags "jruby,core,mnohub,production" --desc "MnoHub Production"
 
# Save the app name to a var to make your life easier
export app=clueless-turkey-1

# Transfer app ownership to your parent organization (e.g. maestrano)
nex-cli apps:transfer $app maestrano

# Link the application to the code package
# NOTE: the S3 credentials must have been provided to you by the Maestrano team
nex-cli apps:scm $app --link s3:mnoe-packages/mnohub/releases:v1.0.31.tar.gz --credentials somelogin:somepassword

# Add the mysql and redis add-ons
nex-cli addons:create mysql $app
nex-cli addons:create redis $app


# Review App and wait for addons to be up (MySQL and Redis env vars should be populated)
nex-cli apps:info $app


# Setup one-time option to load the database schema
nex-cli apps:vars $app --add RAILS_LOAD_SCHEMA=true
 
# Launch application
nex-cli apps:up $app
 
# Wait for containers to be up
nex-cli cubes --app $app --all
 
# Remove one-time option to load schema
nex-cli apps:vars $app -d RAILS_LOAD_SCHEMA
 
# Restart your application to ensure the above change
# is taken into account
nex-cli apps:restart $app

# Check the logs
nex-cli apps:logs $app


# Create the Active Admin Tenant and Active Admin User
nex-cli apps:ssh $app
cd /app
rails c $RAILS_ENV


t = Mnoe::Tenant.create!(name: 'Maestrano', domain: 'activeadmin.com', address: 'Active Admin', email:'active-admin@yourdomain.com', country: 'AU')
t.users.create!(name: 'Admin', surname: 'Active Admin', password: '<GENERATEME>', email: '<CHANGEME, will be used for login>', admin: true)

# Restart the app one last time to have the ActiveAdminTenant activated
nex-cli apps:restart $app

You can now go to the Nex!™ generated URL (e.g. https://clueless-turkey-1.my-nex-domain.com) and check that everything is working properly.

2.2 - Register Log Drain on SumoLogic

You first need to register a Hosted SumoLogic Collector and use the generated collector URL

Go to Manage > Collection > Add Collector
Select "Hosted Collector" (the collector will be hosted by SumoLogic)
1. For the name you should use the same name as the component E.g.: core-mnohub-uat or core-mnohub-prd
2. SumoLogic then ask the type of collector you want. Select "HTTP"
3. Use the same name as the collector for the name of the HTTP endpoint (e.g. core-mnohub-uat or core-mnohub-prd)
4. Select "UTC/Etc" for the timezone
Once created SumoLogic will display a popup showing the log drain URL. Just copy that and use it for the next step

# Make sure to use the SumoLogic collector URL
nex-cli apps:update $app --http-log-drain https://collectors.au.sumologic.com/MY_RANDOM-LOG_DRAIN-TOKEN

2.3 - Setting up a custom domain

First create a CNAME to your app using your DNS manager (e.g. AWS Route53, GoDaddy, etc.):

host api-hub.mydomain.com
# => api-hub.mydomain.com is an alias (CNAME) for enhanced-tuna-1.my-nex-domain.com

# Create a domain
nex-cli domains:create api-hub.mydomain.com $app
  
# Add the SSL certs
nex-cli certs:create api-hub.mydomain.com $app --cert path-to-the-cert.crt --bundle path-to-the-bundle.crt --privkey .path-to-the-private.key.pem
