NAME
gcloud alpha sql blue-green-deployments - provide commands for managing Cloud SQL blue-green deployments
SYNOPSIS
gcloud alpha sql blue-green-deployments COMMAND [GCLOUD_WIDE_FLAG …]
DESCRIPTION
(ALPHA) Blue-green deployment is a strategy that minimizes database downtime when you make changes, like major version upgrades, by copying a production environment to a separate, synchronized staging environment.

With blue-green deployments, you can make changes to a staging environment-the green environment-without affecting the production environment-the blue environment. When you're ready, you can switch over with low downtime, promoting the staging environment to be the new production environment.

These commands help you manage the lifecycle of creating the green environment, testing, switching over, and cleaning up old resources in Cloud SQL.

GCLOUD WIDE FLAGS
These flags are available to all commands: --help.

Run $ gcloud help for details.
