- 4. Versioning strategy Semantic Versioning(SemVer) ● Solution for dependency versioning hell ● intuitive way to track and understand versioning ● Useful for external as well as internal dependencies ○ Microservices architecture ● Version syntax: X.Y.Z ○ X: major version number - backwards incompatible features ○ Y: minor version number - backwards compatible features ○ Z: patch number - backwards compatible bug fixes
- 5.
- 6. Development workflow Base branch ●Usually "master" ● Protected branch. No direct commits. Development branch ● Branch for a feature or fix ● Create Pull Request once changes are ready
- 7. Development workflow Github settingsfor branch protection
- 8. Development workflow Pull Request ●Notifications ○ Slack, email, etc. ○ On creation, approval and merge. ● Checks for merging ○ Approval/code review by a peer or lead ○ Jenkins CI pipeline
- 9. Development workflow Github PullRequest: pending checks and review
- 10. Development workflow Github PullRequest: CI pipeline check passed
- 11. Development workflow Github PullRequest: checks and review completed
- 12. Development workflow PR merged-> Jenkins release pipeline is triggered ● release version bumped ○ tagged in git ○ updated within files e.g. helm chart yaml, package.json, version file, etc. ● release pushed to Nexus
- 13. Version bump Version number ●Maintained in .version file ● major/minor version number bumped by developer in file ● patch number bumped in CD pipeline Project Version file

- 15. GitOps Two separate repos ●Code repo ○ Code of project ○ Built to artifact and/or docker image and/or helm chart ● Config repo ○ Defines deployment configuration ○ Which docker image or helm chart to use ○ Number of replicas ○ Deployment namespace ○ etc.
