Creating  a Pipeline (CI/CD)  on GitLab, using  Docker on an Ubuntu Server.

Introduction:

Continuous Integration (CI):

Continuous Integration is the practice of frequently and automatically integrating code changes from multiple contributors into a shared repository. Developers regularly submit their code changes, which are then automatically built, tested, and integrated into the main codebase. This helps identify and address integration issues early in the development process.

Continuous Delivery (CD):

Continuous Delivery is an extension of CI and focuses on automating the delivery of software to various environments, such as testing, staging, and production. The goal is to ensure that the software is always in a deployable state, allowing for reliable and efficient releases. CD includes automation of testing, deployment, and monitoring, enabling rapid and consistent software delivery.

Docker:

Docker is a technology that packages applications and all their necessary components into self-contained containers, making it easy to develop, test, and run applications consistently across different environments. It simplifies application management and promotes consistency and portability.
