In software development, Git is used for collaboration and version control of a codebase. As a DevOps Engineer, Git is essential for various use cases:
Infrastructure as Code(IaC)
When working with a dev team deploying an application to Kubernetes, you will create various Kubernetes files that need to be managed. If the Kubernetes cluster is on AWS, you can use automation tools like Terraform and Ansible to manage AWS services instead of doing it manually.
These files, along with any Bash or Python scripts used, need to be tracked and versioned just like application code. Git provides a platform for:
Tracking Changes: Git keeps a history of all modifications made to these configuration files. This allows DevOps engineers to see how the infrastructure has evolved and revert to previous versions if necessary.
Secure Storage: Git repositories offer a secure central location to store all IaC files, enabling collaboration and access control within the DevOps team.
Collaboration: Multiple engineers can work on the same IaC files simultaneously, making changes and merging them for an optimized workflow.
CI/CD Pipeline or Build Automation tools
Continuous Integration and Continuous Delivery (CI/CD) pipelines automate the software development process.
A CI/CD pipeline checks the application code, tests it, and builds it. This requires integrating the build automation tool and the application’s Git repository. CI/CD pipelines often automatically trigger builds and tests when new code is pushed to the Git repository, optimizing the development process.
A DevOps Engineer may need to set up this integration, and the process can vary depending on the tool or Git repository.
Specific Git commands, such as retrieving commit hashes or checking for code changes, might be used during the CI/CD pipeline depending on the chosen tools and configurations.
DevOps engineers use Git for version control and collaboration to manage infrastructure (IaC) and automate workflows (CI/CD).
