This tutorial describes the steps to be installed GitLab WebUI server on CentOS 6.x edition. Before we move forward, let’s see what is this GitLab, it’s a web based code repository for management , review and issue tracking. Developers no need to worry about whatever the development methodology, is a waterfall, Agile or any traditional methods, it always streamline the collaborate development workflow up to the CI/CD pipelines.
This tool is basically opensource tool and anyone can setup the server easily for their testing or in-house development. As in git lab it comes with a visualize dashboard with monitoring as well, Further, developers could get stats for the projects as well.

When the development scope is being incremented, the complexity of development, Testing & Releases would be more complicated in Continuous Integration & Continuous Delivery pipelines. Downloading dependencies in software packages, and versioning is even more complicated of frequent releases if there is no well defined mechanism. Semantic versioning is one of the solution for reduce this complicated hassle.
Version is more important to developers to track their historical tracking, it gives a well defined versions of software releases. Therefor it adds more befits to the software development as well as CI/CD pipelines.
Benefits of Semantic Versioning
- Historical tracking of code development.
At any point developers can get the idea of code status from any historical point.
- Universal builds packages are available to anytime deployment.
Build can be triggered from any of previous tags, and it includes all the required dependency and other configurations. Therefor those tags can be easily used for build project deliverable as required from history.
- Easily identify the code changes including API, functional and bug fixes.
- Helps to manage releases and code development.
Semantic Versioning Format
There are three Major parts are in semantic versioning, Major, Minor & Patch.
- Patch : Patch is where the developers change code to bug fixes after production deployment. This part is only changed when other major & minor are remained as it is. And this change should be backward compatible Please take a look on below example.
v1.3.4 //before bugfix
v1.3.5 //after bugfix
- Minor : minor part also a backward compatible changed in functional requirements. When there is a feature development for a release, which is versioned with minor part of the version number, and this feature should be backward compatible. Below example shows the feature development versions.
v1.3.5 // before feature development
v1.4.0 //new feature development
- Major : Major version defines about a massive change with backward incompatible of code change. That may a API change, architectural change or related changes.
In such a major version is released, it cannot be revert back to a previous version since there a backward incompatible changes.
v1.4.0 // before major change
v2.0.0 // after major change
There are some several basic rules that everyone adopts in the semantic versioning.
- Initial development should start with v0.1.0
- When you want to release as first release from the project, it should be changed to v1.x.x
Best practice of versioning is very convenient way of improving software delivery cycles including CI/CD. Since most of the companies are adopting with DevOps and Agile practices, best practice of versioning is most important.
