Ruby on Rails
------
sudo apt install ruby-railties

cd rubyrails-tasks
sudo apt install ruby-bundler (install the bundler package so I can call bundler command)
sudo gem update --system (update bundler version before running it)
sudo apt-get install libxslt-dev libxml2-dev zlib1g-dev (necessary required packages)
sudo apt install ruby-all-dev (necessary required packages)
sudo apt-get install libpq-dev (postgres client libs)
bundle install --path vendor/bundle (run bundler command)


Run the app locally
-------------------
rake db:create
rake db:migrate
rails server


Azure
----------
Create a resource group
--------------------------------------
az group create --name RGLabRadwan --location "East US"

Create postgres DB
--------------------------------------
az postgres server create --location "East US" --resource-group RGLabRadwan --name postgrasradwanserver --admin-user userradwan --admin-password DevOpsAKS@1234 --sku-name GP_Gen5_2

Postgres Firewall
--------------------------------------
az postgres server firewall-rule create --resource-group RGLabRadwan --server postgrasradwanserver --name AllowAllIps --start-ip-address 0.0.0.0 --end-ip-address 0.0.0.0

psql -U userradwan@postgrasradwanserver -h postgrasradwanserver.postgres.database.azure.com postgres

CREATE DATABASE sampledb;

CREATE USER radwanuserdb WITH PASSWORD 'DevOpsAKS@1234';
GRANT ALL PRIVILEGES ON DATABASE sampledb TO radwanuserdb;


Connect local app to Azure Postgres
--------------------------------------
change config/database.yml

production:
: *default
host: %= ENV['DB_HOST'] %
database: %= ENV['DB_DATABASE'] %
username: %= ENV['DB_USERNAME'] %
password: %= ENV['DB_PASSWORD'] %


Run from bash
--------------------------------------
export DB_HOST=postgrasradwanserver.postgres.database.azure.com
export DB_DATABASE=sampledb
export DB_USERNAME=userradwan@postgrasradwanserver
export DB_PASSWORD=DevOpsAKS@1234

rake db:migrate RAILS_ENV=production
rake assets:precompile
rails secret

rails server -e production
