Mastering CI/CD Workflow: A Comprehensive Guide for DevOps Success

What is the significance of pushing images to an image registry in CI/CD?

Image registries store versioned images that are essential for deploying applications in a consistent and reproducible manner.

Why is it important to keep Kubernetes manifests in a separate repository?

Separating manifests from source code simplifies deployment management and ensures version control for configuration settings.

How do feature branches contribute to parallel development?

Feature branches allow developers to work on isolated features without disrupting the main codebase, promoting collaboration and efficient testing.

What is the purpose of a hotfix branch in the CI/CD process?

Hotfix branches are dedicated to addressing critical production issues swiftly without interfering with regular development cycles.

Why is merging feature branch changes into the main branch crucial?

Integration ensures that new features are compatible with the overall project, maintaining stability and functionality.

How does the release pipeline trigger the deployment process?

The release pipeline automates the deployment workflow, initiating the deployment process based on predefined criteria such as successful testing.

What role does the pre-production environment play in the deployment process?

The pre-production environment allows for comprehensive testing of new features and updates before they are released to the production environment, minimizing the risk of deployment issues.

Why is it recommended to use different Kubernetes clusters for each environment?

Isolating environments in separate clusters ensures resource independence and reduces the risk of conflicts or disruptions between different stages of the deployment pipeline.

How do Jenkins multi-branch Pipelines streamline the code promotion workflow?

Multi-branch Pipelines automate the process of building, testing, and deploying code changes across different branches, improving efficiency and consistency in the CI/CD pipeline.

Why is using one Argo CD instance for multiple stages preferred over deploying for each stage?

Centralizing deployment management with a single Argo CD instance simplifies configuration, monitoring, and version control across multiple stages, reducing complexity and enhancing scalability.
