- clona repo
- bygg
- amazon credential
- verifiser amazon oppsett


1. Deploy webapp
----------------
- create eb environment (single webapp?)
- eb deploy
- make a change
- deploy
- verify


2. Autoscaling
--------------
- create new environment with load balancer
- configure autoscaling (2-4?)
- deploy app
- öka load, se auto scale in action (eb health etc)
- nedetidsfri deploy ut av boxen..

3. RDS
------
- create new environment with database (single for speed?)
- evt. .ebextensions for å laga schema på förhand (göra ting mot db som inte ger så mkt mening att göra inifrån appen)
   - yum install postgresql
   - bruk env. props for RDS i .ebextensions för att targeta databasen  (via psql)
   - create schema
- init datasource i app
- ex. bruk flyway i app för migrering till sista version av schemat


Nyttiga ting
-------------
- eb health
- eb ssh
- eb logs
- hur läsa loggar annars?
