Git Branching for Docker Image Promotion across Environments 🚀 - Live Coding Walkthrough
Originally I just wanted to explain why I have git shas in my docker image tags… instead watch me do live debugging and git-fu 🥷 to demo errors to explain fast-forward merges vs merge commits when it comes to promoting code from one environment to another, e.g. from dev to staging.
See real world usage of git revert vs git reset, empty commits, branch deleting, renaming and more.
