Validate Your Configurations in skaffold Workflow

This codelab introduces how to validate your app configurations before deploying them to the cluster. You are not required to know kpt or skaffold before starting the codelab.

After this session, you will have obtained more powerful tools to validate and manage your configurations.

What is kpt?

Kpt is an OSS tool for Kubernetes packaging, which uses a standard format to bundle, publish, customize, update, and apply configuration manifests.

What kpt can help you with

• You can validate each of your config changes declaratively.
• You will get an hands-on off-the-shelf experience about the GitOps CI/CD workflow in skaffold.
• You won't encounter version conflict if the config hydration (a.k.a kustomize) mismatch with the deployment tool (e.g. kubectl).
• You can prune your resources accurately with a three-way merge strategy.

What you'll learn

• How to add a validation to your config changes.
• How to define validation rules in the form of a declarative configuration.
• How to use the validation in kustomized resources.
• How to reconcile your configuration changes with the live state

You can try out this interactive codelab using Cloud Shell.
