Connecting to an existing stack

When deploying multiple stacks within the same environment, the Webscale Control Plane acts as a central dependency resolver. Instead of referencing cloud-provider resources directly, a stack may reference outputs from another stack

For example, you may wish to deploy an add-on stack into an existing network or require the database endpoint of an RDS database. To refer to these values, you can provide references to the outputs from a different stack.

Examples

  "data_subnets": "/v2/stacks/{stack-id}/outputs/data_subnets"
  "public_subnets": "/v2/stacks/<{stack-id}/outputs/public_subnets"
  "db_endpoint": "/v2/stacks/<{stack-id}/outputs/db_endpoint"
  "db_password_secret_name": "/v2/stacks/<{stack-id}/outputs/db_password_secret_name"

Note: A stack that is referenced by another stack cannot be deleted until the dependency is removed.
