Quick start: Multi-environment parallel promotion

Promote product apps between environments in parallel

In this quick start, we’ll learn how to configure parallel promotions across multiple environments.

Parallel promotions are ideal for scenarios like multi-region deployments, where updates must be promoted simultaneously to designated regions before proceeding to a production environment.

We’ll modify the multi-env-sequential-promotion flow to include parallel environments, saving it as a new flow called multi-env-parallel.

Before you begin

• Ensure you have an existing product deployed to more than one production environment.
  For example, the demo-trioapp product in this quick start is deployed to multiple production environments.
• If necessary, add at least two applications to two different production environments before proceeding.

Add parallel environments to Promotion Flow

We’ll enhance the Promotion Flow by adding multiple environments to execute promotions in parallel.

For this example, we’ll add prod-asia and prod-eu as additional production environments to qa.

1. Open the Promotion Flow you created, multi-env-sequential-promotion for the quick start.
2. Open the Settings panel:
   • Name: Change the name to create a new Promotion Flow, multi-env-parallel-promotion.
   • Version: Change the version to 1.00.
3. Mouse over the right of the environment node before the final one in the flow and add the new environments. For the quick start, we’ll add prod-eu and prod-asia to qa.

4. Click Save Promotion Flow.

Below are the Chart and YAML views of the Promotion Flow.

5. Continue with Trigger and view product release for parallel environment promotion.

Trigger and view product release for parallel environment promotion

Triggering a Promotion Flow with parallel environments promotes changes simultaneously across all defined parallel environments. The release is considered successful only after all environments are promoted successfully.

1. Open the multi-env-parallel-promotion Promotion Flow and click Trigger.
2. Select the product, the application to promote, and then click Trigger once again.
3. Click View Release Details.

The Release view displays the parallel structure of the Promotion Flow, with simultaneous promotions across prod, prod-eu, and prod-asia.

What’s next

The final quick start in this series will guide you through creating dependencies between environments to define the order for promotions.
