#1 about 4 min

Understanding the drawbacks of imperative infrastructure commands

Manual scripting and imperative commands lead to fragile, outdated, and complex delivery processes.

#2 about 3 min

Simplifying infrastructure state with declarative configuration models

How declaring a target state separates deployment intention from infrastructure execution details.

#3 about 3 min

Security and stability risks of manual declarative configurations

Executing configurations from local machines causes state drift and lacks automated testing workflows.

Core principles and prerequisites of robust GitOps workflows

Establishing Git as the single source of truth for immutable, automatically-reconciled infrastructure states.

#5 about 7 min

Architecting continuous reconciliation loops with Kubernetes controllers

How automated operators continuously compare and reconcile declared target states against the underlying system.

#6 about 3 min

Managing application lifecycles with the Keptn control plane

Using Keptn as a distributed control plane enables continuous delivery, testing, and automated remediation.

#7 about 4 min

Implementing declarative GitOps workflows using Keptn custom resources

Updating manual pipelines to utilize declarative custom resource definitions and Kubernetes operators.

#8 about 6 min

Demonstrating automated deployment sequences via Git repositories

Deploying and testing application changes by syncing custom resources with continuous delivery pipelines.
