Git Workflows & Git Rebase

  • Mike's git workflow | 00:44:24
    - Branch off dev with name of the JIRA ticket (ie BRD-123)
    - Do changes in that branch
    - Create a pull request into dev once changes are done
    - Pull requests must be reviewed and merged
    - Dev is then tested on QA or preproduction
    - Once testing is done dev is merged into the main and deployment is kicked off
  • If dev is updated before your pull request goes through | 00:48:30
    - git pull origin dev
    - Merge management
  • Git rebase | 00:50:24
    - Combine commits into one making history management easier
    - This can backfire if misused
