Create Application From Template

Introduction

Application templates provide a predefined configuration for creating new applications. You can create an application directly from an application template instead of setting up and repeating the app configuration steps from scratch (such as build configurations, base configurations, CI/CD workflows, and environment details).

Extras

Tags

Tags are key-value pairs. You can add one or multiple tags in your application.

Propagate Tags When tags are propagated, they are considered as labels to Kubernetes resources. Kubernetes offers integrated support for using these labels to query objects and perform bulk operations e.g., consolidated billing using labels. You can use these tags to filter/identify resources via CLI or in other Kubernetes tools.

1. Click Add tags to application.

2. Add your preferred Tags.

3. Click + icon next to KEY field to add a new tag.

4. Click the symbol on the left side of your tag to propagate a tag. Note: Dark grey colour in symbol specifies that the tags are propagated.

5. To remove the tags from propagation, click the symbol again.
