Variables¶

The Variable resource¶

A Variable describes the configuration and value of a variable in a workspace.

In Scalr there are “terraform” and “environment” variables.

Terraform variables define values to be passed into the corresponding Terraform input variable that is defined in the Configuration Version to be used in a run. Scalr Terraform variables are added to the terraform.tfvars.json file in the working directory of the workspace prior to any run. The values passed in can be HCL structures if the hcl attribute is true.

Environment variables define shell variables that are added to the run time environment of a workspace using export VAR=value. These variables can pass authentication parameters to providers or any data required for local processing, such as via local-exec provisioners.

Key path

Description

type* (string)

Available values: vars

id (string)

attributes.category* (string)

Available values: terraform, env

terraform - Values to be passed to terraform input variables of the same name.

env - shell environment variables. They will be injected via export during a terraform run.

attributes.description (string)

Variable description.

attributes.final (boolean)

Indicates whether the variable can be overridden on a lower down the Scalr organizational model.

attributes.hcl (boolean)

Indicates whether the value of the variable is a string of HCL code. Not applicable to env category variables.

attributes.key* (string)

Variable name. Must correspond to the name of a Terraform input variable in the configuration if category is terraform.

attributes.sensitive (boolean)

Indicates whether the value is sensitive. When set to true then the variable is not visible after being written.

attributes.value (string)

Variable value. Not visible after writing with sensitive: true

relationships.account (object)

The account this variable belongs to

relationships.account.data.type* (string)

Available values: accounts

relationships.account.data.id* (string)

relationships.environment (object)

The environment this variable belongs to

relationships.environment.data.type* (string)

Available values: environments

relationships.environment.data.id* (string)

relationships.workspace (object)

The workspace this variable belongs to.

relationships.workspace.data.type* (string)

Available values: workspaces

relationships.workspace.data.id* (string)

links.self (string)
