The document provides an overview of GitOps and Infrastructure as Code (IaC), emphasizing their integration into the DevOps workflow to automate and manage software deployment and infrastructure. Key principles of GitOps include declaration of desired state, versioning, and continuous reconciliation via software agents. Additionally, it introduces practical hands-on labs focused on Google Cloud and Terraform, highlighting tools and methodologies for effective cloud resource management.

5. Git?
Git is a free and open source distributed version control system designed to
handle everything from small to very large projects with speed and efficiency

10. GitOpsPrinciples
Declarative
A system managed by GitOps must have
its desired state expressed declaratively.
Versionedand
Immutable
Desired state is stored in a way that
enforces immutability, versioning and
retains a complete version history.
PulledAutomatically
Software agents automatically pull the
desired state declarations from the source.
Continuously
Reconciled
Software agents continuously observe
actual system state and attempt to apply
the desired state.

11. KeyComponentsofGitOps
The Git repository is the source of truth for the application configuration and code.
1.
The CD pipeline is responsible for building, testing, and deploying the application.
2.
The deployment tool is used to manage the application resources in the target environment.
3.
The monitoring system tracks the application performance and provides feedback to the development team.

Bash Script => Imperative
Containers (Docker) orchestration => Somehow declarative
IaC => Declarative

13. IaCinaNutshell=>
DeclarativeDefinitionofInfrastructure
IaC allows you to build, change, and manage your infrastructure in a safe, consistent, and repeatable way by
defining resource configurations that you can version, reuse, and share.
Allows you to manage infrastructure with configuration files rather than through a graphical user interface.
