Environment variables priorityLink to this anchor
When the same environment variable is injected by multiple sources, the Scaleway infrastructure follows a precedence rule to determine the value for that variable.
The order of precedence, from highest to lowest is the following.
-
Environment variables defined in your command-line environment.
-
Static variables (i.e. variables set in a Terraform/OpenTofu configuration file).
-
Variables defined in the Scaleway configuration file
