  • I’m automatically deploying the production environment as soon as a change is pushed to master
  • I’m adding a step to be able to manually trigger a deploy to staging when develop branch is updated. This is because develop gets frequent changes and i don’t want to run out of my build minutes (free plan has 50mins/month) by triggering a deploy every time.
  • For all other branches (feature/* etc.) i’m adding the ability to manually trigger a build and not deploy anything. This is because i’m not expecting to build feature branches much as they are usually tested locally
  • The variables are all defined under Settings > Repository variables

Notes on Pipelines

You can run an after-script in your step based on BITBUCKET_EXIT_CODE (0 = success, 1 = failed)
