Build script

13. Project lifecycle
from scratch

14. INITIAL STEPS
- drush dl drupal
- copy/paste minimal -> custom
- add base set of modules
BUILD
drush site-install custom Integration
environment
Local
environment
Profile based way

15. pre install actions
- git pull
- delete content file and caches
drop db
drush site install
post install actions
- upload translations
- import content
- frontend build processes

git pull
drush updb
git pull
drush updbhook_update_N
custom_deployment.install

18. pre update actions
- git pull
drop current db
upload db from prod
drush updb
post update actions

20. Typical issues

21. Using equal environments
Prod = Stage = Integration = Local dev

22. Code review inside the team
Developers do code review for each other
- Use common approaches for features
- Knowledge exchange inside the team
- Better quality of code
- Increase responsibility for review code

23. DB manage approach
Use always latest prod db
Preparing prod db for use in development
Daily db backup script from prod
All enviroments should use sinle DB

24. Profits after using
CodeDrivenWorkflow
Fix errors on early phase
Reduce time for bugfixing
Minimizing the impact of the human factor
Simplified everyday deployment
