I'm looking to design a scalable CI/CD pipeline that can effectively support a development team growing from 2 to 13 developers. In my past experience, we often faced Git conflicts, even while using feature branches. I want to know the best ways to manage feature and hotfix releases so they reflect smoothly in production. Also, what are some strategies for making our artifacts semantic versioned? Any advice or resources would be greatly appreciated for navigating this fast-paced environment!

Three key areas to focus on for your setup:
1. **Branching Strategy:** The main issue with Git conflicts often stems from long-lived branches. The ideal approach is to have a single `main` trunk with very short-lived feature branches. Your `main` branch should always be stable and deployable. All new features and fixes should arise from short-lived branches created from `main`, and they should be merged back within a few days to minimize the chance of conflicts. Regular updates from `main` to your task branches using `git rebase main` can help prevent larger conflicts down the line.
2. **Pipeline Flow:** Your CI/CD pipeline should have a clear separation between non-production environments for testing and production environments for deployment. The flow should include:
- **Pull Request Pipeline:** Builds the code and runs tests on the task branch. This ensures nothing goes to production until it's validated.
- **Staging Pipeline:** Once a branch is merged into `main`, a proper release candidate artifact is created for QA testing.
- **Production Pipeline:** This should simply promote the tested artifact from staging, tagging it appropriately before deployment.
3. **Semantic Versioning:** Clearly define your versioning system to ensure everyone understands how versions relate to features and fixes, making it simpler to manage releases and deployments effectively without confusion.
Great breakdown! I’d add that keeping your feature branches small and focused on one task at a time can really ease the merging process. Plus, always running tests on your CI/CD can catch issues early!
