User Story: MVP Deploy

[DeeMcCart]

EPIC: #7

As a system owner I can deploy and re-deploy the system with MVP functionality so that the site operates as expected with MVP functionality

Assumptions or Pre-Requisites:

• Basic site setup is in place EPIC: Project, workspace and core site setup #1
• Debug mode set to FALSE (note that this is now set using an environment variable so longer-term solution)
• First Deploy has been performed and any lessons learned incorporated
• Possibly some additional configuration settings needed in Heroku for MVP deploy (vs first deploy)

Acceptance Criteria: (Must be completed before task is moved to 'Done')

• Must be able to build app inHeroku
• Must be able to run app once built

Tasks - Build ElephantSQL Database

• Start with ElephantSQL and verify database in place... YIKES not there (first deployment took different approach)
• Install psycopg2, dj_database_url - and freeze requirements
• Export data from existing database: python3 manage.py dumpdata products > products.json
• Settings.py: import dj_database_url. Commment out existing DATABASES = and replace with DATABASES= { default: dj_database_url(<my_database_url_from_elephant>)}
• python3 manage.py showmigrations - should see a list of migrations to be applied to the database I am now connected to (the elephantsql database)
• python3 manage.py migrate - to apply all the database structures to the new database
• IF USING FIXTURES to load JSON data: python3 manage.py loaddata categories; python3 manage.py loaddata products;
• create database superuser(s)
• revert database settings in settings.py, remove URL to new ElephantSQL database and save/commit

Tasks - load Data into ElephantSQL database

• Check migrations in ElephantSQL - open up the ElephantSQL console
• Browser - table queries - auth user - execute - should see superuser(s) setup in previous task
• OOPs - just realised - becuase I'm not using JSON I will need to manually key the data into my Production database

Tasks - Prepare to Deploy

• setup secret_key and retrieve it from the environment (refer to 'Deploying to Heroku')
• Add Stripe fields to config variables in Heroku
• If not already done, add a conditional statement into settings.py to link to appropriate database depending on env settings
• Ensure gunicorn is installed to act as web server & freeze
• set Heroku config DISABLE_COLLECTSTATIC to 1 to prevent Heroku from trying to collect static files when we deploy
• create Procfile in root directory to tell Heroku to treat this as a python app/ create a web dyno: web: gunicorn jeweller.wsgi --log-file -
• settings.py ALLOWED_HOSTS = ... Heroku_deployment_name
• commit changes and attempt to build from Heroku

Tasks - Build & Test (without static)

• BUILD IN HEROKU:
• Usual craic with deploy - build

Tasks - Configure AWS for Static files

• CONFIGURE AWS FOR STATIC FILES
• Create bucket,set to public access
• Properties tab - scroll to bottom - static - enable, set default index.html error.html, Save Changes (This gives a new endpoint accessible from internet)
• Permissions tab - scroll to CORS , set to below, then Save Changes
  [{"AllowedHeaders": ["Authorization"],
  "AllowedMethods": ["GET"],
  "AllowedOrigins": ["*"],
  "ExposeHeaders": []}]
• Permissions tab - Bucket Policy - Edit - Policy generator: type S3 Bucket policy; Allow all Principals *; Action: GetObject; ARN: (paste from other tab); AddStatement button; SaveChanges button; GeneratePolicy button; (copy to other tab); insert */ at end of Resource string; SaveChanges button.
• Permissions tab - ACL - Edit - Grant Public: ListAccess; override message; SaveChanges

Tasks - SET AWS IAM (Identity and Access Management)

• Create Group
• Create Access Policy, attach policy to Group,
• Create user, attach user to Group
• Generate keys

Tasks - TRANSFER STATIC FILES FROM DEV TO PROD

• Install boto and django-storages, freeze and add 'storages' to installed apps
• Configure settings.py to use AWS for static and media storage
• Create file custom_storages.py and add some content...
• Commit, build deployment
• Test app
